Moving from T-Mobile US to AT&T - Defy General

Recently moved to a T-Mobile dead zone forcing me to switch providers. As I would like to keep my Defy, I have decided to unlock it and move to AT&T.
Sometime today or tomorrow I will be making the transistion and would like to ask those who have gone before me for some advice...
Preferred ROM for making the switch? (For Example: I'm not sure I completely understand the Bands involved...for a UK ROM, I had to install a patch to get T-Mobile to work, but I don't know how/if it would affect AT&T)
AT&T Software? I can pretty much rip out T-Mobile the software, just not sure about how to get any AT&T specific software I might want/need.
De-branding? Retaining the T-Mobile branded market will just irritate me.
Anything else I should know or prepare for?
Thanks -

Presume you are in the US.
Where I live it's a dead zone as well (for both T-Mo & AT&T) but I use the wifi calling built into the Defy (my wife uses the similar UMA on her Blackberry). The calls are so perfect we could get rid of land lines. AT&T does NOT have wifi calling.
As far as I know there is no ROM that will allow you to run the Defy on AT&T 3G, but I could be wrong. T-Mo is 1700, AT&T 1900 -- both have 2100 for Europe etc. Again, if that's changed someone here will tell you.
I believe roaming -- including data roaming -- domestically is free. That's what I was told by a T-Mo rep, and you may want to double check. But if it is, and you cannot get your phone to work on AT&T's 3G, you may want to stay with T-Mo. Or get a different phone and move to AT&T.

AT&T uses 850 and 1900 and are moving to only 850 which this (US) phone has so it should work in most areas, but I would consider the wifi calling first too as AT&T is much more expensive than Tmo, has data caps and overages unlike Tmo.
Do what you have to do, just be aware of the pitfalls of AT&T.

Thanks for the info. Unfortunately, Alltel was the major roaming provider in the area for T-Mobile, but since Alltel was bought out/merged with Verizon, there is really no roaming in this area any longer.
Wifi is what I am using now, but is extremely limiting, as I am restricted to about 15-20 yards of my living room. There is little to no public WIFI in the area (country living...) and no outside data access though pretty much defeats the purpose of having a smart phone (no Google Maps, remote email, local movie show times, business look-ups, comparison shopping, etc.).
While going with an AT&T phone is an option, I really like the water resistance of the Defy. Since I do a lot of outdoor activities (e.g. hiking) and drive a doorless/topless CJ7 most of year, water resistance is a godsend.
AT&T, while not ideal, is currently my best option.

Does anyone know for sure that an unlocked Defy will work on the 3G 850 freak for AT&T? I recall that some protocols also need to be on a phone for it to register on a specific network.

Looks like this guy got it working on androidforums. Sorry, no links for me yet.

Should I go for Verizon touch pro 2 or something else??

Hi
I'm new to the US, and I'm not familiar with the wireless companies system here..
I have some question:
1. Which service provider is better? I'll be living in Berkeley, CA?? I keep hearing that At&T has bad reception.. which one should I go for??
2. The 30$ data plan: all companies say that this plan is unlimited, but I keep reading (at least for Verizon) it's 5 GB/month.. is this true?? and are there any companies that offer real unlimited data plan...
Because I was thinking of using my phone as a modem for my PC, I don't want to pay more 30-40$ for DSL if I already have a true unlimited data plan
3. Roll over minutes: does this apply only to AT&t, or all carriers?
Thanks in advance guys

I just left AT&T due to extremely poor customer service. AT&T is the only carrier that offers rollover minutes, but their 3G coverage is spotty, and when switching from 3G to Edge or vise versa, you will experience a lot of dropped calls. If you want to use your phone as a modem with AT&T you have to get a tethering plan which will run you $60/month. Verizon has a much larger 3G coverage area, and you don't have to worry about the network being burdened by iPhone users. Sprint has rolled out 4G coverage in some areas with plans to expand. Sprint has cheaper calling plans, but their subsidized phone prices are higher. All in all, do your research, and check online for reviews of coverage, network speed, and customer service.
1. reception obviously varies by location. VZW probably has the best claim to the best nationwide coverage--their business model has very much focused on network building, and up until very recently, their phone selection sucked because they didn't invest as much in securing great smartphones. Alternatively, ATT has focused investment heavily on having great phones, and haven't focused investment as much on building any of their networks.
That said, ATT has great phone reception in a lots of metropolitan areas. There might even be some areas where they have better coverage. And while their 3G data coverage isn't nearly as broad, where it exists, it has been tested as being the fastest (especially when you're not using an iPhone).
2. No, all wireless carriers have a cap of some kind. Further most will charge an extra $30ish a month on top of the $30ish a month for smartphone data for tethering (using your phone as a modem), and they'll still have a data cap.
3. I don't know VZW's plans.
ive been with ATT for YEARS and their costumer service can kiss my ass because i never use it. why? because they offer best reception where im at. why would i want to find out how good t-mobiles costumer service is? i just want a reliable network. all carriers have crappy prices and conditions here. just find the one that works for you and dont listen to what anyone else says. why would you care if verizon has 3g in montana and att doesnt if you live in LA?? its irrelevant. find the least crappy one for you and stick with it.
Do some research on the difference between CDMA and GSM networks. One may work better than another in certain situations.
T-Mobile has cheap rate plans and free tethering.
Sprint has a WiMax network rolling out, although all of the carriers are working on LTE or some other standard of 4G- Not really a concern at this point, since few phones support it.
Verizon has the best customer satisfaction ratings, but their phones are often locked down with software.
AT&T has a history of dropping calls, but has the fastest recorded data speeds.
No matter whom you may chose, you will end up disappointed over some facet or another. You will need to get DSL or some other form of land-based internet, unless you can keep yourself constrained to the 5GB data caps that ALL of the carriers have.
I guess I'm gonna go with verizon then..
I asked a Veizon representative today about the Touch Pro 2, and he said it's only CDMA ... although on their websitethey say it's GSM Quad Band!!! Is there anything that I'm missing?
Will I be able to use out side the US if travel home?
cheers

Yeah, it's kind of misleading. The Verizon Touch Pro2 is actually a CDMA/GSM hybrid device, which works on Verizon's CDMA network or any GSM network. In theory, you should be able to use it on any GSM network in any country as long as you have a valid SIM card.
you cant trust advertising. it makes it appear that all options are shiney. verizon claims all of its wireless technologies as 3g no matter what they are, whether they have speeds slower than atts 2g or worse. the verizon touch pro will not actually work in the us or canada on gsm. you also need to pay for vodofone service separately to get international coverage. you can flash a radio that will let you use atts network but youll loose the cdma network verizon uses. sprints 4g network is not as promising as i hoped. its slower than atts 3g network and to use it you have to buy a $10 1-day pass that will let you use 4g in about 10 or so cities. its also not on any phones. in terms of data or unlimited plans, i would probably have to recommend t-mobile. even though i think they have the ugliest version of the touch pro 2. verizon does limit there unlimited plans to 4gb a month i think. and yes att is the only one with roll over. i never use my minutes so i up to about 10000 minutes rolled over. i will never be charged overage as long as i live.
I was with ATT when they were known as Cingular for three years. One day I got a call and they said I was using it off their network too much and I had to stop it or they would cancel me. Since I was not even living in their area, it was not going to happen.
So I signed up with Verizon, which did not even sell phones within a hundred miles of where I would be using it. That was in March of 2007. I went to Alaska for 16 months where it roamed constantly. Not a peep from Verizon about not being on their network. When going to a remote village for more than a month where no cell phone would work, I would just call them and they would suspend my phone for the time I was there. No bill at all and no charge for turning it off. So I have to say the customer support from Verizon is the best there is and ATT is the absolute worst.

thanks a lot for your help guys, I really appreciae that.
I have one final question: Is there a way I can buy verizon touch pro 2 without a contract, and use it with verizon prepaid service (if that is possible in te first place)?
I'm new here and I don't have many people to speak with, and since I'm a student, I could use any some extra money

I purchased my VZW off contract. Unsubsidized is probably about $500.
Different carriers have different rules for their prepaid services. With GSM carriers, TMo and ATT, it's easy to pop a prepaid sim into any phone. With CDMA (Sprint and VZW), I'm not sure. Best bet is to call and ask.
well i had sprint for ever...I switched to tmobile.. to get that tp2 free through wmdeals.com even though coverage sucks at my house im happy.. I have wifi for data when im home.. when i leave my home i have edge service everwhere.. til i start getting close to mesquite ( texas ) it goes to 3g.. but edge works great with opera mini.. and for updating certain things.. but so far tmobile rocks..

That's where you are wrong. They did cancel me and one of my brothers living in another town shortly after I got the call and letter. The explanation was they had contracts with other providers to cover you when your were roaming. And roaming was fine, as long as you did not do it too much. I roamed all the time, for about three years.
I called Verizon today, and the representative said that I can't use their prepaid service on a smart phone... although I'm not really sure about, as she sounded clueless, and I had to do lots of explanation until she got the basic idea..
anyway... I like really the verizon version of the Touch Pro 2..
If I go for month-to-month and get it for full retail (490$).. can I cancel with Verizon after that, and unlock my phone, then use it with some other network like T-mobile or At&T????
I never used CDMA before, and after reading some info, I think GSM is better for me, at least for now...

You never know with reps. I seem to recall that VZW's prepaid might have some unlimited data intended for dumbphones, which of course they wouldn't want you to use with a smartphone.
There are MVNOs, like Page Plus, that use VZW's network, but have prepaid plans where they probably wouldn't be concerned about smartphone usage (pay per kb instead of unlimited).

You can get it unlocked here and use it on ATT or TMo (minus 3g, 2g data still works), and as to whether you can cancel after the fact without penalty, it depends on exactly what you signed up for at VZW.

well then double check because att hardware can not utilize tmobile 1700 band. if you in the country you are never going to use another carriers network. and roaming only applies to out of country. even if you stand anywhere on the canadian or mexican borders, you wont be charged roaming. the system isnt that fd up.

Well, that's not entirely true. AT&T devices can use T-Mobile's network, just not HSPA (3G), and vice versa. Before I got my 8925, my main phone was an old T-Mobile Blackberry 7200 which I unlocked to use on AT&T. It could make phone calls and browse at EDGE speeds just fine. The 3G bands are f*cked up internationally since they often differ by country and carrier, but the EDGE and basic GSM bands are pretty much compatible with any GSM phone (since most GSM phones are Tri-band or Quad-band capable).
In addition, it's perfectly possible to use another network in the same country. If a company like AT&T doesn't have infrastructure in a remote area and wants to add service there, they'll often strike a deal with a local carrier who does. It's usually a seamless transition for the user, and it doesn't generally cost the user a cent. Rather, AT&T is the one paying the local cellular operator for allowing the AT&T customers use the local carrier's network as opposed to the alternative of having no coverage in that area. AT&T got mad at texascbx because he was costing AT&T money by roaming on these local carriers, which AT&T had to pay.
Lastly, I know people who live near the borders and they always are careful to see which operator they are using. One of them lives near the Mexican border, and has to make sure he's on AT&T's network before he makes a call. If he doesn't check, he might be roaming on the TelMex network and will get billed outrageous fees for a simple call, even though he's in the US.
I was at the mall today, and I talked to a T-Mobile guy, and he said I can get the T-mobile version of touch pro 2 for full retail, and I can use it with their prepaid plan without any porblems.
Then I spoke with a Verizon representative, and he said that I can't do that on their network, however I can buy the device with out a contract and without any plan...
So my Final question (and I guess fortunz answered before,but I still feel like asking coz I don't want to through 500$ away)... If I get the Verizon Touch Pro 2, and get it unlocked here

[Q] G2 on AT&T?

Hey guys, new to Android and T-Mobile. I got a G2 last week, and I live and work in kind of a fringe area for T-Mo coverage. AT&T has good coverage out here, but the G2 doesn't roam over to ATT, I can't even register on their system when I select it in the mobile networks settings. My question is- how can I set the phone to roam onto their system when I lose T-Mo coverage? (I have heard that T-Mo can roam to ATT on EDGE). Thanks!
As far as I know, the only way to use AT&T on the G2 would be to SIM unlock the phone and use an AT&T SIM with an AT&T account. The TMO SIM won't just allow you to roam because they don't have a reciprocal billing agreement --- though I am no expert on this.
I believe, though I could be wrong, that the G2 does not have the ability for 3G (UMTS) data on AT&T. As you stated, if you could connect to the network, Edge should work.
One solution would be to switch to an AT&T SIM and use the Samsung Vibrant, which has the ability to connect to one of the two AT&T 3G bands. Of course, if you want to use AT&T regularly, getting an AT&T phone would be a better solution. So, for you, unless you want to switch to AT&T, wifi might be your only solution.
Ugh! That is exactly what I was hoping I wouldn't read lol. Well, I do really want to stick with tmo, just wish my phone would auto roam to att when I lose the tmo signal. Thanks for the reply!
Sent from my G2 using XDA app
I asked around at work a bit, and there are cases where you can roam on AT&T's network. These cases exist in areas where T-Mobile has not, cannot, or will not build out a network. In these cases, they contract with AT&T to provide their customers with network access. Some phones will show roaming, but I think the software, at this point, has made it a seamless experience, and you don't even know you are attached to AT&T's network. For billing, purposes, if you have a national plan, you are not roaming.
This doesn't help you, but I wanted to clarify my blanket statement above.
Check out the coverage map (Select NO for Are you a Rep, then go to the Data Coverage Map):
compass(DOT)t-mobile(DOT)com
Unfortunately in your area of CA, there is no roaming partner.
The only roaming in CA is in some parts of N. CA up Hwy 1 and 101, towards the Oregon border, and in the 395 corridor.
I'm thinking of upgrading from my HTC Rhodium on ATT to a Desire Z (also on ATT). Is there anything I should be looking for to make sure it will play nice with the 3G network?
Thanks

[Q] Hardware, roms, and 3G frequencies...

Hi - I'm looking for some good answers - I think I know the basics...
After much shopping, I bought 2 of these...
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170623785892&ssPageName=STRK:MEWAX:IT
(HTC Touch Pro 2 s - the wife likes for our phones to match so I can teach, set up, etc...)
I think they are called T7373 SEA's South East Asia Versions, and I flashed to 2.07.707/4.49.25.91 radio just fine to get current at WM6.5. (I like factory ROM's - the books work, etc - despite my appreciation for the effort to cook.)
Now - I'm currently ATT, and when they go to Data Plan me, I'm going to T-Mobile prepaid.
So - I get to looking at 3g frequencies - of course!
The book for the device says 900/2100 HSPA/WCDMA.
The sellers' ad says
3G Network HSDPA 900 / 2100
HSDPA 850 / 1900 / 2100 or HSDPA 1700 / 2100
(It's not really clear what the 'or' means)
Now, I'm not *****ing at the seller, I want to really understand, and they knew I was US and they asked ATT or Tmobile.
Would they like have reached into one of three bins, to sell me one of three truly different hardware phones - OR - picked a phone up and flashed it (Radio or full ROM) to my provider, or did they just configure the existing system so it picked Tmobile and its freqs for instance? (When the phone boots, it asks T-Mobile or 2 other Asian-sounding systems) How else could the phones do as advertised? (9/21, 8.5/19, or 17/21)
If the frequencies are not a settings, but a ROM/Radio issue, can I load the 'other US guys' flash and have it work?
If not, does anyone know what really is changed in the hardwares (I imagine the antennas' length might vary by X%, but then here that's % of mms.)
Thanks - great answers and experience really appreciated!!
The device in the picture of the ad is a European unbranded model (RHOD100). It's 3G frequencies are on the 2100MHz band. If they sent you the one pictures, you will not get 3G with any US provider. AT&T uses 850MHz and 1900MHz for their 3G service, while T-Mobile uses 1700/2100MHz. 3G radios are hardware dependent, not software dependent. This means that you must purchase the device that contains the radio for the 3G service you wish to use. They will work on 2G networks anywhere in the world. 3G is really the only difference between carriers.
The AT&T device is the RHOD300 model, also known as the Tilt 2. The T-Mobile version is the RHOD210.
The short answer is that if they send you the exact device in the picture from the ad, you will only be able to get 3G in some parts of Asia and Europe.
The description on the eBay listing is just cut and paste from somewhere (like HTC's website), so that is why it says "or" for the 3G bands. One is for the Euro model, the other is for the Asia model. Either way, neither have the correct bands to give you 3G on AT&T or T-Mobile. And as cajun mentioned, bands are hardware dependent, and there is no way to change it.
If you want 3G on AT&T, you need to buy the AT&T branded Tilt2. But since they will be able to read the IMEI number of the phone (since its ATT branded), they will probably add a smartphone data plan very quickly. So its probably not even worth getting a Tilt2, if you don't want a smartphone data plan. If you want 3G on T-Mobile, you need to buy a T-Mobile branded TP2.
Bottom line, if the phones you bought are unbranded, then they don't have the correct hardware to get 3G on either AT&T or T-Mob.
THX
Hey guys(?) thanks, I think I understand.
So - basically the ad HAS to be a lie, at least for 3G.
So I'm still wondering... What does HTC actually change in the phones - a crystal (I doubt this in modern times), a chip, a pack, an antenna length? There is a small area in the phone that looks 'potted' we used to call it.
They are way too pretty, and way too functional 'as is' to mess with (so I'm not gonna go module or whatever shopping), and we are pretty much 'emergency only' web people (for maps, pizza places, etc) and 2G will be fast enough. The value of a keyboard for texting, the Windows interoperability, and no damn contract is good enough.
We are deciding which ROM level we want before we try ATT to see if they know the numbers... T-Mobile prepaid is the backup plan.

A lie in that it looks like a lazy cut and paste, with either no proof-reading to catch the error, or a seller that does not fully understand what he is selling. They are a high volume seller, and also just used stock photos (not photos of the actual item), so its just a rushed auction posting. I don't think it was an intentional lie meant to mislead you. But if you want to dispute the sale, I think you have very good grounds, since the information in the auction is incorrect, and its actually impossible to tell what exact model (Euro or Asian) they are selling from the description.
AT&T most likely won't be able to correlate the IMEI with the right phone brand/model. But I've seen cases where they think its a smartphone, but the wrong one, and try to add a smartphone plan. I read a post where a guy was using a Nexus One, and their system was reading it as a Blackberry. I think he just told them it was an unlocked dumbphone, and they removed the smartphone plan.
Please Correct me if I'm wrong...
presently I'm using Sprint Touch Pro 2, and I have read on the internet that it is possible to work with AT&T or T-Mobile (which uses different technology other than Sprint's CDMA) after proper unlocking. Is it possible?
Regards.

Yes, but you will not be able to use any other network's 3G service. The best you will get is EDGE on another network.
To follow up...
ATT stuck me on $25 Smartphone within 24 hours. (We went to $15 later, and they dropped us to a $10 cheaper talk plan.) For this particular set of phones, apparently the first 8 or so digits of the IMEI is phone type (which they clearly knew from Tilt 2's) and the rest is item serial number. Couldn't argue there...
Speeds, freqs... I don't get a clear definition of G's anywhere, but I show a H before I long on, and another H with bars as I use data. I have used cellular data at up to 1.1mbs per speed sites - I don't know if that's over E, or G, or H but it seems pretty fast to me. All that's on ATT, when I went to the T-Mobile store and tried their card, the best I got was 200kbs on about 5 tries.
Love the phones, added HTC task manager pulldown, and 1.6 VC from here - THX

G stands for GPRS, and it is a 2G service. It stands for General Packet Radio Service. It is the slowest data service you can get with speeds normally under 50Kbps. It is occasionally known as 2.5G service.
E stands for EDGE. It stands for Enhanced Data Rates for GSM Evolution. It was a revision to the 2G service implementation and features speeds from about 100Kbps to 250Kbps depending on location, service provider, and signal. It is occasionally referred to as a pre-3G technology. It fits in the ITU's definition of 3G, but few people refer to it as such. It is normally marketed as 2.9G.
UMTS (Universal Mobile Telecommunications System) was a revision to the voice service, and did not address much data-wise. This was the first widespread usage of the term and use of 3G. It is normally the service that your device is using when it shows the 3G icon. 3G speeds are normally 350Kbps - 500Kbps.
H stands for HSPA. It stands for High Speed Packet Access. It is one step higher than what is commonly known as 3G.It is also known as 3.5G. It features speeds closer to 1.5Mbps. HSPA is normally grouped in with 3G service when it is being discussed.
As for your test with T-Mobile, that wasn't really a fair comparison since you can't get 3G speeds on a Tilt2 on T-Mobile's network. You can only ever get EDGE service. Therefore, you were comparing AT&T's 3G service to T-Mobile's EDGE service. This is like trying to race a Mustang with a Moped. If you get the Rhod210 model, you will get the faster connection with T-Mobile. There isn't much to compare between AT&T and T-Mobile. AT&T 3G speeds are slower than T-Mobile. The services are also much cheaper on T-Mobile.
THX for reply, I generally understood all the abbreviations, but like you said - the marketing hype really seems to very from the technology.
If I saw, regularly, over 1 mbs and the H bars to the right of the H block, do ya' think I was H/HSPA over 8.5/9/19/21 freqs?

On AT&T it would be HSPA on the 850MHz and/or 1900MHz frequencies. T-Mobile uses 1700MHz for HSDPA and 2100MHz for HSUPA. The frequencies for 2G services are all the same for everyone. This is why you will get up to EDGE service with any GSM carrier, but never 3G service unless you buy a device that explicitly supports that carrier's 3G service.

[Q] GT-N7100 incorrectly shows roaming on T-Mobile USA

Hi,
I just received an unlocked International Galaxy Note II in the US. Ordered from Handtec in the UK, and the phone appears to be the French model. I have observed what I think is a problem when trying to use the phone on T-Mobile USA.
I put my T-Mobile USA SIM card in the phone, and the phone thinks I am roaming. Uhhhh no. It's a T-Mobile USA SIM card on the T-Mobile USA network. It is NOT roaming. Now, it probably doesn't have any impact beyond the "R" notifier, and a "Roaming" page which shows up on TouchWiz, but it DOES make me feel very uneasy. I have to enable "Data use while roaming" to be able to use data while on my home network!! It's crazy!
To those who will point out, yes, I know that T-Mobile USA has their 3G currently on the AWS 1700/2100 band, which the Note II does not support. I am therefore using EDGE with this phone. (Yes the data speeds suck, but T-Mobile's refarming will make this problem go away in the next few months). Even though I am on EDGE, I am not "roaming" unless the Note II's definition of roaming is different from mine. I am still on the home network, regardless of whether I am on 2G or 3G.
Has anyone else seen a problem like this?
If I can't figure this out in the next day or two, I may return the Note II and just wait another month or so for the T-Mobile US version. (Probably that's what I should do anyway, but I figured the GT-N7100 would get more developer support).
Hope someone can help!
Thanks!
Edit: I forgot to add - I also have and unlocked international Note 1 GT-N7000 and an unlocked iPhone 4. Neither possess the T-Mobile USA 3G band, and neither of which show roaming when I'm using T-Mobile USA. So, either T-Mobile did some funky network work today which changed something, or there is something different (and possibly a bug) about how the Galaxy Note II determines if it's roaming.
Unfortunately I cannot be of any assistance to your issue, just wanted to comment however. I find it very odd that ALL Note II's don't work on every frequency. Bear with me, I'm under the impression that they are identical hardware wise, every version. So, maybe it's a simple matter of flashing a different radio.img? Not that there are any available currently, but there will be shortly. I hope (think) it will be similar to the ATT Note on Tmo. Hopefully it works out better though. We still don't know if the Tmo Note II will be HSPA+42 or not, but it will support next years Tmo LTE.
So, as of now, this is a little bit of a disappointment for Tmo customers looking for the N7100. Hope you can find a workaround for at least HSPA+21 soon :good:

That happened to me as well using my International Galaxy S3, I dug into it for about a month and trust me, it's something with the phone detecting that it can't connect to the HSPA+ bands it supports, and when it "defaults" down to EDGE it considers it "Roaming". Stop digging for answers, I was at it for weeks, this is the reason.
You wont get charged for roaming or anything though, so use EDGE until T-Mobile's refarming finally happens; I waited for 2 months and nothing, so I jumped ship and got Straight Talk. I use over 15 GB of data a month, no throttling, $45 bucks. :good:
Hope this helps, because NO ONE gave me a straight answer, Dont even bother calling T-Mobile, they're of absolutely no help. I flashed all sorts of custom ROMs, Kernels, Network Tools, Diagnostics, etc. trying to figure it out. It's just the way these Samsung phones (GT-I9300 and N7100 by the looks of it) work when their 3G/HSPA+ bands are not supported.
Cheers!

farfromovin,
I agree it's a complete pain why one model can't work worldwide - or even between carriers in one country, the US!! I'm not sure that all the revisions are the exact same hardware though. Certainly the different revisions will support different LTE bands from one another, different 3G bands (ie T-Mobile USA) and even different technologies (VZW, Sprint, US Cellular CDMA). Whether there is one uber radio chip that's the same in all versions, with different bits enabled here and there, I don't know. I would doubt that a chip currently exists to support all GSM, UMTS, LTE and CDMA bands in the one, but you never know.
I really cannot wait (getting super sick of it) until T-Mobile's 1900MHz refarming, and finally all UMTS/HSPA phones will work on pretty much any UMTS/HSPA network worldwide. But just as we finally get 3G harmony, LTE comes along with a zillion different bands, and we're back to where we were at the start of GSM, and the start of UMTS - all over again.
As far as getting the GT-N7100 to work on T-Mobile AWS bands - unless the radio supports that band somewhere, and can be enabled by some hacky flashing, I don't think there's much chance. I followed a thread for a while which was trying to do that for the original GT-N7000 and it ended up nowhere unfortunately.
I'd be very, very surprised if the T-Mobile US official Note II did not support DC-HSPA +42. Given how TMO pushes that, I don't think they'd sell a phone without it these days. I'm kind of surprised the GT-N7100 doesn't have it, to be honest, but I guess it's not yet that widespread, and most carriers will bypass it to go to LTE.
Cheers!

Hey Ars-Hexis,
Thanks so much for the reply. I googled about the same issue on the i9300 as you mentioned - and sure enough a couple of threads on androidcentral, and tmobile support - and all with pretty much a bunch of people going "what?" I think you're right, and this is either some crazy change which Samsung has made to the "S3" generation of phones, or it's an unintended bug which was introduced. I contacted Samsung support on twitter but I'm sure they'll tell me to go away since this is an international model and not sold or supported in the US.
I would love to have this properly reported to Samsung though because it is NOT correct behaviour, and I'm sure it does not meet the 3GPP standard behaviour. These phones' definition of "roaming" is frankly wrong. It's possible they know about the bug but don't care about it too much, because it only affects the minority of importers or travelers, and then only on the very few networks which use AWS band for 3G.
The phone and data works fine of course, so it's really a cosmetic annoyance. However, if I was actually outside TMO's network without knowing it (maybe camping on to some network on the Canadian border or something) then I'd never know if I was actually roaming or not. So the phone's roaming indicator, by being permanently false, is useless in the times when I'm actually roaming. Since this is not a likely scenario for me to be on the Canadian border and roaming onto an AWS-only network any time soon, I'll not worry too much about it.
Yes, I'm really sick waiting on this refarming. It's a huge undertaking of course, so I understand why. I do have a Straight Talk AT&T SIM which I got for my Galaxy Note 1, however I don't use it often for several reasons: haven't ported my number to it, am wary about data throttling or cut-off, and I find the data hit or miss on Straight Talk anyway. I heard stories about people being warned or cut off after 100MB in any day, but if you're saying 15GB and no throttling, it may be something I want to put to the test!
Thanks a lot for your reply! It's nice to know I'm not crazy!
Cheers!

Hey there! Sorry I hadn't answered in such a long time. We'll actually I've found that the S3 (sold it) and the Note 2 (own it) some how cannot be tracked for data usage correctly by straight talk. It's quite interesting... I ported my number over from T-Mobile, so if you have an S3 with a T-mobile prepaid sim... I think you have nothing to lose! I'm in Dallas and regularly get around 3-4Mbits/S during high usage hours and 6-7Mbits/S after 7 pm when network usage goes down.
There have been 2 occasions over the past 2 months where I'm throttled for like an hour and suddenly it gets uncapped on its own (?!?!?) lol. Last month I used about 25 GB... It's insane. Btw, if you if get throttled for real (happened to me once), you can just call them and say your "Internets is slow" (act technologically challenged) and they'll reset it.
Ah 1 last thing: I got the at&T ST sim card when I switched.
Cheers!

I just got my International Note 2 today, and I am using it on the T-Mobile network also. I am seeing that I am roaming but my data is off and I am just using wifi. I have turned off my phone and back on again and its still showing. But after reading this whole thread I am getting that is a bug or something along those lines is that correct? Thanks.
I really need to know

roaming
I am on prepaid tmobile and I have Roaming sign only in areas where I used to loose signal with my old phone . Basically when I go in Garage underground my signal starts getting weaker and weaker and then roaming kiks in and signal is up all the way . T-mobile does not charges for local roaming . If you use USA tmobile and you are in usa you are fine . My texts and voice are still the same rate for me . When I had Chinese rom it was showing all the time , now I flashed German t-mobile and R shows only sometime , but it does not bother me .
Hope this helps .
I too have a Note II (GT-N7100) I purchased in Thailand in December. I use it on the T-Mobile network and have the same issues with the "R" symbol. I am located in Tampa Bay area, Florida.
T-Mobile was indicating to me in January that this was an issue in weaker signal areas for their data network as they prepare to refarm it. Don't know if this explanation is entirely accurate, but I find in my local area that the R symbol goes away in certain areas and it behaves "normally". This includes the area where my T-Mobile office is located. It seems to be somewhat of a patchwork network, and for some reasons certain areas cause it to go into the Roaming mode.
I was just on a trip with stops in Los Amgeles, San Francisco, and Philadelphia and noted the same behavior in some of those cities: Getting normal signal indications in some places, and Roaming in others.

[Q] International Note...confused

...as in "I'm so confused" ala Vinnie Barbarino!
I bought my GT-N7100 and thought that since it supported the same bands as my old phone (Huawei U9000), that I would have the same capabilities from my carrier (Cincinnati Bell). After 4 days, 3 visits to my CinBell store, calls to their tech support and to Samsung; I'm resigned to 2G for the remainder of my contract.
I'm really not looking to try and do any major (to me) surgery to software/firmware...I'm just trying to get my head wrapped around this crazy patchwork quilt of cellular bands and figure out what options I have to get 3G at least, once my contract is up in June.
From reading threads here and elsewhere...it seems like AT&T is one...that would not require modifying the phone. Am I correct? Are there better options? I can live without 4G. I'm certainly not a heavy mobile data user...I just like the ability to browse a bit when no wifi is handy!
Thanks!
Yes, it will work with AT&T 3G post paid contract, AT&T pre-paid GoPhone service, Or Straight Talk 3G which uses ATdT network as well.
