I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.
No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much
no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.
One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G
I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.
let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).
when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

hmm, now I think the T-Mobile Touch Pro2 works on ATT's 3G Network.
It should also work worldwide too.
oooh, European bands, "standard" North American bands (they're not really standardized, neither in the US nor Canada and Mexico is barely getting 3G into place), and no idea what the last one is for, sounds like cdma...

Obviously this is some bull**** because it supports all of the 3G frequencies of worldwide carriers and american carriers.

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.
seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

My Xperia X1a shows UMTS (900) even when I check the settings... IN FACT only the X1i supports
It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

I'm a little green when it comes to 3G stuff, but please correct me if I am wrong...
Yes, you can put foreign SIM cards in US TP2's but not get 3G coverage in Europe. On the other hand from what I have read, European TP2's (even the unbranded ones) will not work with 3G is the US.
And if I am wrong... can someone please point me to a TP2 that will work on 3G networks in most of the world?
Or does one have to have two TP2's to enjoy 3G.. one for the US, and one for Europe, etc.?

The only limitation I'm aware of is a NA TP2 won't work w/ NA GSM 3G.

Until someone hacks it
I can't remember where I read it. But someone said if you wanted 3G in Europe, better to get a Euro unbranded model.
So perhaps this is under the assumption that it isn't hacked... not sure.
Slightly, off-topic Q but rather than start a new thread.... once a HardSPL is out for both the CDMA and GSM TP2's... will they effectively be "equal" devoces?
I really would like to pick-up a TP2 in the next few days... I like the VZ unit, but it's CDMA and since I travel quite a bit, really prefer and need more of a GSM phone, but don't like the TMO as no 3.5mm jack.

The Verizon unit already has international GSM bands unlocked, AND international (2100MHz 3G). If you've been a Verizon customer for 60 days or more you can call them up and get an unlock code for free and use any SIM card in your phone so you can get a cheap prepaid SIM and not pay the high Verizon roaming costs. There's also a small (I'd say around 25%) chance that the NA 3G bands will be found/unlocked, but at this point who really knows if they are there or not.
Actually the Telus CDMA TP2 supports the European 3G bands but not the American ones becuase technically you will be using it in North America on CDMA and outside America on GSM. So its the other way around
It seems that if you have the Sprint TP2 that it won't register at all on US GSM networks, but comes unlocked by default.
On Verizon (which I have) a simple phone call to support they'll give you the unlock code and you're good to go. I use an Orange (UK) Sim in mine just fine in the US and others in other forums have reported that using US SIM's from TMobile/AT&T work fine also in the US.

I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings.
Just have to make sure that your provider gives you a 3G SIM (most of them are these days) and that you have the 3G service enabled on your account in the respective country.
Many people say they can't pick it up yet don't have it on their account, or think that their EU provider will automatically provide it as part of the roaming service... which is not a good assumption to make.

3G in North America? I doubt that. The phone does not support North American 3G bands. Are you sure it was 3G in North America??
Man, this is all confusing... I swear somebody has to come up with an HTML table of what phones work with what and where and stickify it.
Can people just put this to bed already!!!
The Sprint (North America) TP2 is suppossed to be used on CDMA in the US and GSM worldwide, hence the GSM radio is unlocked for outside America GSM use. This is how it comes default. If that is so hard to grasp, then there is no hope for some, sadly.
As for the title, the TP2 is a world phone, it works in the US (and North Ameria) on CDMA and elsewhere unlocked on GSM. That to me is the true definition of a World phone from a U.S CDMA perspective (and especially moreso as this is the CDMA version).
To put it in perspective, a Sprint customer (in this case, moi) gets the best of CDMA in the U.S and when traveling to visit his sister in High Wycombe in the U.K (like i'll be doing this Autumm) gets to pop in a PAYG U.K sim in the same phone and use it while over there. This phone doesn't get any "worldlier" to me than this scenario!!
Is the O.P attempting to specifically define a dual mode CDMA/GSM-unlocked World phone as not world phone because it's locked by default from doing GSM in it's primary market which happens to be CDMA (and in this case Sprint)?
This is not rocket science folks, it really isn't.

Point taken. It's just that with that same Sprint phone (correct me if I am wrong), you can't travel to Canada pop in a Rogers SIM card and get Rogers 3G.
Wouldn't the phone want to swing towards it's CDMA cousin, Telus or Bell?

AT&T 3G runs on 850/1900 GSM, the TP2 supports both of those bands, how would it not work with 3G on AT&T in the US?
T-Mobile runs 3G on 1700/2100 GSM bands, both of which aren't included on the TP2, as far as my research has lead me to believe.
Basically while it may be a quad band GSM phone, it is only a dual band 3G device. It comes in two flavours - UMTS 900+2100 or UMTS 1900+850
The 900/2100 version is far more common than 850/1900

"it Depends"
The US CDMA phone operates in 3 modes.
1 CDMA Only
2 GSM Only
3 'Global' (whatever it can find).
If you have it in Global it will generally take the CDMA local carrier over anything else. However, not always. I've had mine switch to GSM for a bit then go back to CDMA. But mine is Verizon and unlocked so it works everywhere in the US and I also have a UK sim card in it. So I'm a little 'different'.
But, in any case, you can tell the phone which mode to use if you want. All upto you.

(verizon TP2)
here we go again... (tp2 3g na)
"I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings."
So, maybe he's wrong. But either way...
You wanna know why this keeps coming up again and again?
(not because we're all dumb and thick headed, which we may very well be)
But,
Because we just have trouble imagining them hardware "band amplifier" hobbling the hardware when it's so much easier to do it somewhere in firmware.
We all know that the less you fiddle with the hardware for multi-region functionality the less you have to fiddle with the production line and fiddling with the production line is the Last Thing a manufacturer wants to do.
Someone even once said that there wasn't room in the Rhodium platform for quad band data support. But now we're expecting the tilt 2 to do just that.
So, all protestations aside, those of us who paid ~700 us clams for this beauty, and who like the kbd layout.
And who have like me (as quite the Early Adopter), forked out for an sx56, sx66, 8135, x7510((quad band data)
Just feel a leetle wee bit of a sense, dare I say it, of Entitlement for the TP2 to be enabled into a fully world wide phone.
So we keep hunting, and digging, and dreaming, and .... posting.....
well here is my two cents i have the original unlocked euro version of the tp2 and all i get in the us it edge. it is really impossible to get 3g in the US (2100) because this version of the phone literally does not have the attena for it. and so that you can see all the different types of tp2s and the technical and physical differences between them here is a link: http://pdadb.net/index.php?m=pdacom...&id3=1792&id4=1829&id5=1766&id6=1989&id7=1751

3g in the USA must be on the 1700 band then, as thats the only gsm band that the euro version doesn't support.

TMOUS version

Anyone know of a good site to order a prepaid SIM card? I plan on using my VZW TP2 in Spain and France. I was also wondering if I should or could disable data and use my TP2 with Garmin XT so I don't get nailed for data usage. Your thoughts would be appreciated...

Well, it's just as the title of this thread says... I have a Tmobile's G2 (A.K.A. HTC Vision), which its 3g default bands are under 1700 / 2100. Here on my country, all the providers have their 3g services on 900 / 2100.... soo... Is it possible to Flash T-mobile G2's Radio, an set it to work on 3g 900/2100 mhz, so I can use the phone on 3G, instead of that annoying and extremely slow EDGE??
Or, is there a Custom ROM that has these settings on it? (I mean, a rom that automatically turns the 3g band to 900 instead of 1700)
Thanx.
No you can't, the radio bands are set in hardware (e.g. the physical antennae in the phone), not just in the radio software.
Why would you need to, the phone would use the 2100 band for it's 3G in your country? I took mine to Russia and it worked fine.
I don't think it's that simple. I only get edge on my T-mobile G2 using the Rogers network.

Rogers doesnt use 1700 or 2100 so that is to be expected. The original posters country has a 2100 3G, I would suspect he just isn't in a coverage area.

I don't think it works like that, I think it needs both bands to work. If it was that simple then surely they wouldn't bother making different phones for different markets (e.g. T-Mobile US vs Europe/Asia)
That may be...I'm only speaking of my experience in Russia, they have 2100 only 3G and mine worked without the second band.
Just to add, T-Mobile US use the 1700 MHz band for the uplink, and 2100 MHz for the downlink. So presumably the phones (i.e. G2, as opposed to the Desire Z) are physically setup like that too.
Oh I thought Rogers uses 2100. Either way, no worky.... sad.

Ah, I think I'm following you, because Russia exclusively uses 2100 for up and down my phone worked, but since his county has a seperate uplink and a downlink band it won't?

Yeah I think that's it. I don't know *that* much about this myself, just picked up on a few discussions about the G2/DZ on here over time.
Have a look at this - http://en.wikipedia.org/wiki/UMTS_frequency_bands
I think the "problem" is that the G2 uses exclusively "Band IV" for 3G (i.e. 1700/2100 split), but somewhere like the OP's Dominican Republic uses Band VIII (900).
What the OP needs is a Desire Z, which operates on Band I (2100) and Band VIII (900).
Russia appears to use Band I (2100) as well. Maybe a G2 can partially work there then ?
Rogers uses something else, Band II (1900) and Band V (850).
As I say, I'm don't know that much about this myself, so if anyone else can help clarify/confirm/deny, then that'd be great.
Much appreciated.
Sent from my HTC Vision using XDA app.
Via Google, I dug up another interesting piece of info.
Although it's not on HTC's official spec list on their site, on T-Mobile's support pages it says that the G2 does Band I as well. Which would explain how it would have worked in Russia. That's not going to help the OP's problem though.

Wow mega confusing, but you helped clear it up, thanks!!
Mine worked very well in Moscow, I was pleasantly suprised, it was kind of a bonus to be able to get on the web, I wasn't expecting much.
I don't understand why the manufactures don't provide phones with penta-band 3G support like the Nokia N8. Maximize profit when producing 2-3 same phones with different frequencies maybe? I mean quad-band GSM has been supported for pretty much all of the current phones, why not 3G bands as well?
Has anyone tried this option?
bring up the dial pad and dial
*#*#info#*#* (aka *#*#4636#*#*)
press "Phone Info"
you'll get the screen with the imei, phone no, network and a button that says "Run Ping Test" at the top
press your "menu" button
when the menu pops up, it'll have 6 options, select radio band, view sim address book, view fixed dialling numbers, view service dialling numbers, get PDP list, and More.
Choose the first one "Select Radio Band" then select the appropriate band.
Not sure if it helps in this situation, but I found it in a thread about gaining 3G in Europe on the N1
hey bro.. I read from one topic in TMo's official G2 forum that the G2 will work on a country with only a UMTS band of 2100 both for up and down (the answer is from TMo employee, an engineer)... hope you'll be enlightened. I bought an unlocked G2 and I researched extensively before purchase. Im from the Philippines which only supports the 2100 band for 3G. I Know and Im 100% positive that the phone will support the 3G band here in my country. cant wait for my G2 (arriving tomorrow)
btw... coverage is vital. if the 3G signal is weak or non-existent in your area, you'll be switched to edge for data on your phone (naturally).. good luck
sorry.. cant post the link. would've loved to have posted it.

That's the Band I thing that I was talking about, that T-Mo shows on their spec sheets (but HTC doesn't seem to list, for some reason).
I think the G2 will do 3G if any one of the two bands are supported by the country. Correct me if Im wrong

There is nowhere in the world that uses 2100 in both directions. Band 1 is 1900 UP, 2100 DOWN.
In all cases, your phone must be able to upload on the frequencies that the towers listen on, and download on the frequencies that the towers transmit on.
I.e., north america vision transmits on 1700 or 1900, receives on 2100.

I am using a sim card I received from SK Telecom when I got my Samsung A... but really, who would use a Samsung A if you have a G2 on hand?
Thank you
The T-Mobile G2 and HTC Desire Z have different radio hardware if I have done my research correctly. The G2 has been customized for the NA (USA) cell networks and frequencies, not sure if this would line up with the Korean networks as the G2 cannot get 3G on any USA network other than T-Mobile.
You'd get better luck with the Desire Z (European or Canadian version) as these radios are true world phones. Correct me if I'm wrong =/

I think you're wrong, but its not clear. The G2 appears to have both Band IV (1700/2100 MHz AWS) that T-Mob uses for data, and Band I (2100 MHz UMTS). The 2100 MHz for Band I is not the same as the 2100 MHz for Band IV. So that is where the confusion lies. Specs listed online (even on T-Mobs website) are not completely clear on this band compatibility (whether the G2 has Band I), and you will find web discussions about this if you search around, that raise more questions than answers.
Band I is what Korea uses for everything (voice and data), so an unlocked G2 should work, if in fact the phone has Band I. In searching around the internet, I haven't found any references to Korea specifically (or Japan, which also uses Band I for voice and data). But I've found some post by people that have used unlocked G2's in Europe, and 3G appears to work fine. So in theory, the hardware should work in Korea.
So either there is something else going on, that is preventing the OP from connecting. Or the G2 in fact lacks Band I.

I'm travelling to Korea tomorrow for a wedding and I'm in the same boat. I think this may have something to do with it

Do you have any other info on your resolution to this problem?
You can. They partially opened their network, so if it is just individually being used (not commercial sale or anything), then you can register your G2 to your account only, so you can use your phone in Korea. Visit any cooperate stores ( both SKT, and KT will do).
I am using G2 in Korea as well. So good luck!
OK...the Desire Z only supports 900 and 2100 MHz which is European and Asian 3G bands. Is there any way that it can be made to operate on any North American 3G bands (like 850, 1700/2100, or 1900) or the issue is entirely hardware related, in which case nothing can be done. I should note that the phone has already been upgraded to 2.3.3 so the rooting options are rather limited.
Any contribution will be highly appreciated!!!
Its hardware limited to the bands you have. My understanding (correct me if I'm wrong) is that with that device (if it is unlocked) you will be able to use a T-mobile SIM to get 3G in the US. I'm not 100% sure with this though, as I don't think the DZ has 1700mhz which is needed for T-mobile.
You don't have the correct bands for AT&T 3G. There is a Canadian version of the DZ that will work on AT&T in the US on 850/1900, however.
The device is completely unlocked and unbranded but its specifications clearly state that its 3G frequencies are 900 and 2100.T-Mobile's 3G is 1700/2100 (together) and it's different from the European 2100. Unless the North American bands can be activated via a secret menu, or by flashing a different radio (impossible with 2.3.4), the phone, as is, can't connect to American 3G networks...only GSM 850 and 1900.
So, a miraculous secret menu appears to be my only hope, which, of course, is impossible to implement if the hardware doesn't support it!
Thanks for your concern!
Well, with you phone, you can use only half of tmo's 3g service since they reserve one band for uploads and the other band for downloads. So technically you kinda get 3g, but just 1 way.

I'm afraid that i can't do that either because the TMO's 2100 3G frequency spectrum is not the same as the European one!
I think I'll exchange it with a friend's European Nexus S which is tri-band 3G and, besides 900 and 2100, it supports TMO's 1700/2100 band! It is an excellent phone but I slightly prefer the metal and the weight of the Desire Z despite the fact that I do not particularly care about the physical keyboard!
Thanks anyway guys!

yea. i think mputtr brought up the correct point. The way T-mo uses 3G is 1700 and 2100 separately for down/up, so like you said its different than the Euro 2100 spectrum.
Sorry it didn't work out.
