[Q] HTC One M8 Developer Edition on Verizon - One (M8) Q&A, Help & Troubleshooting

I have looked elsewhere and am having trouble finding a site that compares the HTC One M8 Developer Edition side-by-side with the Verizon edition. Does the developer edition support the same frequencies as the Verizon edition? I have an activated Verizon SIM card from a Galaxy S3 that I can cut to nano size, but I want to be sure that it will support voice and data frequencies.
I see on TechnoBuffalo (can't post the link because my post count is too low) that the Google Play edition supports:
The HTC One (M8) Google Play Edition will support the 850/900/1800/1900MHz GSM/GPRS/EDGE frequency bands, 850/AWS/1900/2100MHz WCDMA bands with support for HSPA+ 21Mbps networks, and the 700/850/AWS/1900 LTE bands with support for 2600/1800MHz roaming.

I'm wondering: if the developer edition supports all of these frequencies as well, is that sufficient for functionality on Verizon?

The developer edition doesn't have CDMA radios so doesn't work on Verizon or sprint. It sucks to be on CDMA carriers like Verizon or Sprint, always choose a GSM carrier like TMobile or ATT you will have more option than useless carriers dictating what phones you have to use.
Your only option is to wait for HTC/Verizon to release a CDMA developer edition model.

Damn, I was hoping it would perhaps fallback to GSM voice roaming...
Wish I could switch away from Verizon but the deal I'm getting is too good ($30/mo for unlimited data).

I wish T-Mobile or AT&T were choices for me. Where I live, only VZW gets signal..and it's strong LTE. I also have no option for high speed internet at my rural home. But I do have unlimited data. So, for $90 a month I have my home internet as well as LTE everywhere I go. Been a very long time since I've seen the 3G icon. I do have an AT&T sim in my Nexus 5. If they ever expand, I'll know. However, the valley in which I live seems to hate HSPA networks. I can't get any signal whatsoever from any other carrier.

Verizon doesn't support "falling back" on GSM in any way. Sometimes when the frequencies say "WCDMA" it can be confusing, but the only time you can get a phone to to work for voice/sms on Verizon is if it suports CDMA (you'll have to look for the correct bands). Now, that doesn't mean that you wouldn't be able to get an LTE signal if you put your Verizon SIM card in it. It would work the same way the 2013 Nexus 7 works, LTE Only.
It would have to support the following:
700 MHz Block C 13 LTE 4G
1700/2100 MHz AWS 4 LTE 4G
via Wikipedia
Oh and I'm currently getting Unlimited LTE Data on T-Mo with their $20/month data plan. It's worth looking into if you have the coverage.

Galaxy nexus and AT&T?

If we buy the Verizon version, unlocked, will it work on AT&T? Is this going to be an option, or just importing it from uk etc?
Could of swore i read somewhere that att's lte will work on a slightly different mhz that it won't be compatible with verizon's lte, someone correct me if im wrong.

The "AT&T" one, which at the moment is the same as the "world" version will NOT work on VZW.
As of now there are 2 models of the Galaxy Nexus: 1) CDMA/LTE (for Verizon in the USA) and 2) GSM/HSPA+ (for the rest of the world, yes including AT&T and T-mo in the USA).
As of now, there are no GSM/LTE versions (I'm assuming this is what you're looking for on AT&T). If you use the GN on AT&T, it will have HSPA+, but not LTE. And no, the VZW version will not be able to be unlocked and used with an AT&T LTE SIM card, because AT&T is only operating data on LTE, and you'd get no voice/text (assuming you somehow got the device unlocked to accept the SIM in the first place).
Unless Samsung/Google have some kinda curveball lined up to announce a 3rd model with GSM/LTE for AT&T, that will come in the future. As of now we're not aware of this model.

You are correct in saying the Verizon Galaxy Nexus will not work with an AT&T SIM. However, the reason you provided is incorrect. Currently, both AT&T and Verizon operate data only LTE networks. Neither provide LTE voice (Voice Over LTE aka VoLTE) but both plan to (Verizon in 2012 and AT&T in 2013). Whether or not the Galaxy Nexus can take advantage of VoLTE is another open question but it will be able to use CDMA voice either way.
The real reason your Galaxy Nexus will not work on the AT&T network is the LTE frequency bands are different as well as the obvious 2G and 3G CDMA/GSM incompatibilities. A Verizon Galaxy Nexus with the an AT&T SIM (assuming you can unlock the device) will never be able to find the AT&T network. Hopefully, future devices will offer software programmable radios that can be unlocked to interoperate on multiple bands. There are plans for some 43 LTE bands worldwide!!!
So I'm guessing that by the same token in Canada, if your with bell, getting the LTE version is pointless?

Thanks for a little more information, but I said just as much. Even if you somehow got it unlocked to accept a different LTE SIM card (don't think it'd ever happen), there are several reasons why the phone wouldn't work. Even if they did have the same LTE frequencies exactly (or you hacked it on), he wouldn't get any GSM functionality out of the VZW device.
Basically what I was trying to express is that the other things could theoretically be overcome with software/firmware hacks (VZW and ATT will operate in the same spectrum, just slightly different frequencies), whereas you can't ever overcome the fact that the CDMA does you no good on the AT&T network.
Overall I think the point has been made regardless...
dont forget sprint and other cdma carriers in US

Verizon Note 2 Vs. T-Mobile Note 2

Which Note 2 supports more networks and frequencies; and therefore, which would be more suitable for international travel. Is the Verizon Note 2 even pentaband?
T mobile version because it's gsm which is going to work overseas. Verizon is a CDMA and I haven't read that it has gsm support.

Yup, the T-Mobile version will work in more places overseas -- Especially Europe. Just in case, you might want to ask this in the Verizon area also just to make sure. :good:
I'm confused because on Samsungs website, http://www.samsung.com/us/mobile/cell-phones/SCH-I605TSAVZW-specs
the Verizon Model has the GSM frequencies,
is it GSM if unlocked; i believe the Note 2 is already unlocked by verizon, will it work on GSM frequencies internationally?
correct me if I'm wrong, thanks
the verizon Galaxy Note II apparently has the GSM radios,
also has LTE; doesn't AT&T LTE work along same frequencies as verizon LTE
or is the verizon LTE exlusively to CDMA?
All Galaxy Note 2 devices seem to have all WCDMA, GSM, and LTE bands.
But what I understand is that Verizon version is considered as a "world" phone. I know that they tell me that I can use their Galaxy Note 2 on the European Networks.
I have played around with the bands on my T-Mobile Galaxy Note 2 and can get the WCDMA and LTE working. So I don't know if the Modem firmware in all Galaxy Note 2 are the same and just need to be activated by the carrier's sim card or not. Someone please educate us on the this. I know that their is talk of needing OTA update to activate the LTE within T-Mobile GN2. But if the Modem is all the same then can just updating or exchanging the sim card could do the same? Or does the nv file also needs to be updated to activate the band/s as well?
The question is not if Galaxy Note 2 (all verisons) have the bands. But how to (the actual process) activate the band, in question, and get the Galaxy Note 2 in working order with the carrier of choice? What is the method? How to do the process of this method?
Please correct me if I am getting this wrong.
^ good point, and also just to ask about the verizon note 2 again, i thought it carries carries an an additional radio for CDMA, does this mean that the verizon note 2 model has better capabilities worldwide' since it is virtually compatible with all networks in the world (simply tweaks to the frequencies to the radio can get the verizon variant working virtually anywhere) please correct me if I'm wrong here. thanks

Problem I have seen in the past with Verizon world phones is that the game frequencies only work overseas. And lte is gsm band. Which is one of the few reasons Verizon phones have a sim slot to begin with

All recent Verizon LTE phones have GSM radios built in as well as their own CDMA/LTE radio. The LTE radio is only compatible with their network.
Some of these phones are even shipped out of the box unlocked and can be used immediately on GSM networks in the U.S.
If you do get the Verizon Note II and want to use it on T-Mobile, it will not have support for their HSPA+ 42mbps network, I believe it maxes out at 21mbps, as with all other Note II's around the world except for T-Mobiles.
But doesn't Verizon use LTE on the 700 band just like AT&T and future TMobile LTE?

So the Verizon Note2 is like the AT&T Note2 & Sprint Note2 (supporting 21Mbps HSPA+ but not 42Mbps like T-Mobile) but all only with their own respective LTE?..wouldn't it be more cost effective for Samsung just to make 1 phone with all the hardware to support all (isn't the iPhone5 like that now?) or is it cost prohibitive or do carriers not want to make it easier to unlock?
Are we still confident that the T-Mobile Note2 is the best if we want the flexibility to use on all carriers? How often is >21Mbps HSPA+ seen in real world use & why is the disabled LTE not listed at http://forum.xda-developers.com/forumdisplay.php?f=1877 ?
So, which is better then, Verizon or T-Mobile? Verizon's Note 2 also includes a CDMA radio whereas the T-Mobile version does not. If you are using the Note 2 in the US, wouldn't you have more flexible options in terms of which carrier to use?

So do we consider the Verizon Note2 even more carrier flexible than T-Mobile's Note2 (as I was about ready to buy the T-Mobile Note2 to try their $30/mo plan but now having some doubts..if I want this tomorrow I need to order soon) ?
-Thnx
Well LTE On the Verizon Note 2 is only compatible with Verizon's Network. Even if unlocked; the phone's firmware only recognizes LTE if only the Verizon 750 band is detected. Verizon has its own exclusive LTE bands compared to AT&T and Future T-Mobile LTE (sharing the same LTE bands)

I cannot speak to the CDMA radio issue, but I am positive that Verizon LTE will not work with any GSM LTE phone. The frequencies are similar, but Verizon is using a different LTE protocol. I asked that question a long time ago, thinking that LTE would finally allow roaming between Verizon and AT&T, but they are too clever to allow such a democratic system to function. They will remain fundamentally incompatible, not because they need to be, but because they want it that way to keep you locked to your carrier by your choice of device. Nice, eh?

The Verizon NoteII will (in theory) connect to any gsm carrier. How to do so, I don't know.

^^^ Well, the Verizon Note 2 will not be able to work with another carrier's LTE than itself.
my experience
Hey folks,
I've got the Verizon Note 2 and I love it. If you're willing to unlock the bootloader and then install a hack onto your device, you'll easily be able to swap the SIM card out and use it just about anywhere. Yes, the phone is carrier unlocked (not the same as bootloader unlocked). The issue is that in the settings, they won't let you add the specific APNs for the carriers you need. I"m not sure how else to get around that without installing some of the hacks. I managed to do it and it works beautifully on Canada's Bell Mobility, HSPA+ is screamingly fast and the LTE on VErizon in the States is just insanely fast. My recommendation: get the Verizon version because they've built out their LTE much more than their rivals at this point.
On anantech the reviewer stated that the tmobile version would be the most compatible. If you get vzw note2 and switch you wont get lte on tmob or att. Quite frankly vzw is too expensive and the coverage from tmobile is getting better by the month. Not to mention their business pricing is better than any of the other carriers.

[Q] Why AT&T has support for more LTE bands?

I was looking at the tech specs for the new HTC One and T-Mobile has less support for LTE bands.
Is it just a matter of HTC referring only to the bands that matter to each carrier or is it actually a question of different radios.
I ask because apparently the Google Play edition follows T-Mobile's hardware (possibly to provide support for both US GSM carriers), and makes it a no deal for international customers that need support to other bands.

In the review on Engadget they say there are 6 different versions of the phone. It seems the everyone who got it early for review received the international version without US LTE support. These are the radios for the AT&T and T-Mobile versions.
http://www.engadget.com/2014/03/25/htc-one-2014-review/
GSM/EDGE (850/900/1800/1900) (All)
HSPA+
AT&T: (850/1900/2100) with HSPA+ up to 21 Mbps
T-Mobile: (850/AWS/1900/2100) with HSPA+ up to 42 Mbps
LTE
AT&T: (700/850/AWS/1800/1900/2600)
T-Mobile: (700/AWS)
I've been looking into it myself because I'd like to get the T-Mobile version and flash the GPE rom and it does look like the GPE is the same hardware as T-Mobile's copy.
I really hate how these companies make a bunch of different hardware configurations. They're obviously capable of putting all the radios in one device, LG did it for AT&T, T-Mobile, and Sprint with the Nexus 5. N5 on T-Mobile is my current phone, I'm still trying to decide if the M8 is a worthy upgrade.
Yes the lack of compatibility between the two carriers is extremely annoying. I have the Dev Edition of M7 right now and it irks me to no end that I am stuck with AT&T with it. I'd totally buy the M8 if it supports all the frequencies of the AT&T version PLUS AWS for HSPA+.
I travel overseas a lot and I am very disappointed that I get more usage out of my old Samsung Galaxy S2 than the M7.
So how does this translate for M8 bought from somewhere else but used on T-Mobile network. I have ordered the M8 from Amazon (Prime shipping FTW), but it does not mention LTE bands.
http://www.amazon.com/HTC-One-M8-Unlocked-Warranty/dp/tech-data/B00J3554KE/ref=de_a_smtd
If I assume all non carrier branded M8 are the same, would the Play store description be accurate?
https://play.google.com/store/devices/details?id=htc_m8
Play store description mentions "700 MHz, AWS", which is a match with the engadget article "T-Mobile: (700/AWS)".
Would flashing a different radio software allow getting past incompatibilities, or the hardware itself is set to specific bands.
EDIT:
Just noticed this note at the bottom of Play Store page:
Compatible with AT&T and T-Mobile in the US. Check with your carrier for details about coverage.

From quick research, T-Mobile will get LTE in 1900MHZ by "end of 2014". I think I need to ask around a bit on Amazon/T-mobile and research some more...

Someone with more knowledge of radios can probably give a better answer than me but, as I said earlier, at first glance it looks like the Play Store (GPE) version has the same radios as the T-Mobile version. There's also a YouTube video of someone using a T-Mobile sim in their Verizon copy and it worked although, according to the data in the Engadget review, I don't think data speeds are as fast as they would be with the T-Mobile specific phone, at least on HSPA+.

I just looked at the one Amazon is selling and it seems to me to be a Sprint version, although I don't know that the radios listed are actually correct since the Engadget article said all versions will support GSM/EDGE (850/900/1800/1900) and there's no mention of those on the Amazon product page.

Not sure, but maybe the data over there is not accurate? Even the Amazon M8 page for ATT version shows the same information.

This thread over on the M8 forum does not have much concrete info either:
http://forum.xda-developers.com/showthread.php?t=2694630
The radio situation is indeed a veritable mess. I wonder if there are any real tech/cost challenges which limit the radio compatibility or is it just the carriers being evil. I assume a standard hardware chip across all devices will be easier and cheaper to put in, so it must be the evil carriers forcing HTC then.
I am somewhat banking on the fact that unlocked phones (the one on Amazon) are most likely to be GSM compatible. Must get in touch with Amazon customer care I suppose rather than ranting here.
The Anandtech review actually shows that the GPe version combines the best of AT&T and T-Mobile!
http://www.anandtech.com/show/7893/the-htc-one-m8-review
It should work for both carriers.
It is instead missing WCDMA 900 so not optimal if you want to use it in Asia/Europe.

I did see somewhere that the DE has AT&T radios and the GPE has T-Mobile but that really doesn't make a lot of sense. I trust Anand so I think they're probably the most accurate.

No, T-mobile version will work for AT&T but not for Verizon.
What a ridiculous mess! Carriers shouldn't dictate what bands the phone comes in and they should all just be released in ONE model for GSM and all carriers get it.
I understand needing special models for Sprint and Verizon but for GSM its getting ridiculous.
Even the tmobile version doesn't show the 1700 frequency. Isn't that a requirement to be fully compatible with tmobile??

2G = YES
T-mobile version loses spectrum for LTE due to spectrum deals and HSPA+ spectrum support.
Qualcomm charges to license spectrum for their radio chips. Also it requires more hardware to support more frequencies. There has to be give and take, and would you pay $900 for the HTC One if it supported more frequencies?

Really? Apple has all the bands in one model. $350 Nexus 5 has all the necessary bands. So it is bull that it costs more, they just screw up every time. By the way I use the unlocked model and enjoying the M8 but no excuse for not having a single gsm model.

Sorry I firmly believe Google subsidizes a bit of the cost for their phones. They are using the console model to generate revenue.
Apple devices have a premium cost compared to majority of the items out there and doesn't include how much they make from iTunes.
The T-Mobile version is cheaper than the other GSM models.

Ok I will give you one more example...Sony unlocked devices in Sony store cost same as HTC One and they have all the necessary radios to work perfectly on r T-Mobile and AT&T. It's not that hard you know if you want to do a single gsm model.
And no Google is not subsidizing $500 or something, may be little bit they take a hit on profits from selling hardware but in no way they are fools to subsidize huge dollars. Like T-Mobile was selling Nexus 5 for $500 or something? Which might be the actual price.

Yes and No.
The HTC website quotes:
Networks: LTE Quad Band (Bands 17/4/2/5); LTE MIMO; GSM/EDGE: Quad-band (850/900/1800/1900 Hz), Class 12; UMTS: Tri-band (UMTS 850/1900/2100MHz), HSPA+Category 14xx (HSDPA 21Mbps/ EDCH 5.7 Mbps)
Without AWS (1700) for UMTS...you would be limited to T-mobile's LTE area only (Band 4). You will not get 3G connections.

what is the difference between unlocked version, gpe, and developer edition?
Unlocked - can use on any compatible network, locked bootloader, Sense 6.0
GPe - can use on any compatible network, locked bootloader, stock Android
Dev Edition - can use on any compatible network, unlocked bootloader, Sense 6.0

This would be good news for me, but the HTC.com support person (would they be from Let's Talk, which seems to be the the HTC.com e-commerce provider) was saying that T-Mobile LTE is not supported for the Developer edition. I have been considering canceling that order and wait for T-Mobile version to come out, but would hate any bloatware etc.
I hope the HTC support lady was wrong. How can one confirm?

It is supported, the developer edition is nothing but a ATT SKU. It has all the radios except AWS for T-Mobile HSPA in non refarmed markets. See the first page of anandtech review which has the different models along with the radios.

Thanks, The anandtech review is indeed quite comprehensive, quite impressed. I am convinced that the Dev Edition will work with T-Mobile HSPA+ at least as I am in one of the refarmed areas. Hope LTE will work fine as well though the experiences of people over on the M7 forums worries me. Even if LTE remains locked on T-Mobile, it would be great if a software/radio flash would work to enable T-mobile LTE on the Dev-edition, though I could not find a mention of anyone successfully doing that in M7 forums

Well if you are in a refarmed area then you will have hspa+ or 3G on the 1900 band. You don't have to flash anything to enable LTE since the dev edition has both tmobile and AT&T LTE bands. Only thing missing in the dev edition is the AWS 1700 for HSPA and since you are in refarmed area you will get HSPA on 1900.
Personally, I will wait for the tmobile version on 11th and as soon as we get S-Off I'm going to fully convert it to a dev edition. In that way I have the full tmobile radio as well as HTC sense minus carrier crap.
Would getting the google play version now be just as good as the t mobile radio, if not better because it has better resale-ability to AT&T users as well?

Yep the Google play edition is the one with max hspa and LTE radios. Basically full compatibility with T-Mobile and ATT. ATT and Dev edition are same as Google play edition minus one band ( AWS 1700 HSPA band). T-Mobile edition has very less radio and not fully compatible with ATT LTE.
There should have only been one gsm model, that is the Google play edition model. Then they could put whatever ROM they want based on ATT, T-Mobile or stock android.
Morons at HTC just make life tough for us.

I think the blame rests on the carriers, AT&T in particular as they wanted to discourage people moving to T-Mobile with the crippled hardware (or software, I hope it is this one). AnandTech page suggested as much: "As far as I can tell only the AT&T and Google Play Edition SKUs support carrier aggregation. The two SKUs are quite similar from a cellular standpoint, with the AT&T model locking out UMTS band 4 to discourage movement to T-Mobile."
I understand that Band 4 is AWS 1700MHz (like you mentioned).
HTC are probably not in a great bargaining position with the carriers because of its own financial situation. I think Apple has been able to override carrier requests because of its superior position and carriers not being able to remove iPhones from their roster.
BTW I think I am fine with getting the Dev edition from HTC as it is cheaper than GPE(and has no tax) and arrives sooner than the T-Mobile one, with potentially more resale value having AT&T bands.
Can u flash any carriers roms with the gpe?
Does anyone know if there is any difference frequency/band-wise between the dev and att versions?

Yes you can, at least with M7 it was possible. And once you get S-off you can fully convert one model to another including model Id, cid etc.

Yeah makes sense man. Forget the carrier versions which they don't have control. At least the Dev and unlocked editions should have been based on gpe model instead of the ATT. That was totally with HTC control, but may be financially just made sense for them to use ATT model. Whatever it is hopefully they fix this next year.

Yes M8 Developer Edition supports T-Mobile HSPA (1900MHz) and LTE. The refarmed areas with LTE cover over 200 million users now according to T-Mobile. The M8 GPe includes AWS HSPA (1700MHz) for T-Mobile.
I'm using M8 Developer Edition on T-Mobile LTE right now with zero issues.

[Q] Moving S4 from Verizon to iwireless/t-mobile

Hi,
I am thinking about moving my Galaxy S4 and moto RAZR from Verizon wireless to iwireless (a t-mobile affiliate). I understand that I need to unlock my phone but I am unable to find out if I move it to iwireless if I will still have 4G data. The iwireless sales rep said that I will still have voice and 2.5G service but couldn't tell me if I would still have 4G.
I was looking at this table I found on a site explaining how to unlock the phone but I don't know enough about the subject to make an informed decision.
Samsung Galaxy S4
Can someone confirm whether or not my Verizon S4 or RAZR can be unlocked to work with the iwireless/t-mobile 4G network?

It seems as though your grasp of the subject is strong enough to know that it might work as you'd like - and it might not. You need to call back and ask to speak to a CSR that actually knows what bands their service works on so they can give you accurate information. That's kind of their job...
Also -
Verizon LTE operates on Band 13 while T-Mob operates on Band 17, both of which carry completely different spectrums; this means no LTE on either of your unlocked phones.There's a slim possibility that you will get intermittent 3G but the most likely scenario is that you will get talk, text and 2G / 2.5G only.
Band 17? My Verizon branded S4 is getting T-Mobile LTE. I'm fairly sure its on band 4.
T-mobile is band 4 which is 1700/2100 mhz. The Verizon s4 is not capable of 1700mhz. But if you are getting 4G it may be because your area is using 2100 mhz. I am specifically moving to iwireless and I was told they use the 1700 mhz band.

Yes, I think all Verizon LTE capable phones are unlocked.
The I545 (Verizon S4) can receive LTE on band 4. T-Mobile serves LTE on band 4. The coincidence works well.

My RAZR MAXX HD definitely wasn't SIM unlocked... For the life of me I couldn't get it to work when I moved to ATT from Verizon... Not even GSM would work.
I just need to get some clarification from you guys. Are your VZW phones bought in the US and being in the US on t-mobile's or iwireless's 4g network. Because after I made the first post I went to the phone unlocking place in my local mall and talked to there techs, they said that the VZW S4 will not get 4g. I have also been doing extensive searches online and keep finding half saying it will work and half saying it won't. I have a feeling that the ones that work are working outside of the US as I found posts saying as such.
I read some where that the razr you had to flash the radio FW to get GSM to work properly.

I got my vzw S4 off craigslist but 99% sure it was purchased in the USA. I'm on T-Mobile's $50/mo plan.
Verizon's LTE phones are sim unlocked due to an agreement with the FCC when vzw purchased some bandwidth.
I think there was an update around 03/2014 that enabled band 4 on the I545. Then had to make some apn changes and tell the modem to use gsm/lte on band 4.
The one quirk I have is it will say "no service" after a reboot and until I make or receive a voice call. Then I get the "T-Mobile" instead of "no service" and things work as they should.

I'll have to go to iwireless and have one of the tech put a SIM card in my s4 and razr to give it a try.
The only options I have for the network mode on my s4 is
Global, LTE/CDMA, and GSM/UMTS. Can you post you settings?

I was just at iwireless today and tested my phone with their network and was unable to get it to work. iwireless is a t-mobile affiliate but they do not use 4G LTE in my area. Their system runs on a 3.8G 1700MHz which the VZW S4 does not have. I am told that they will be starting to switch all the 2G radios in the area to 4G LTE later this year, which should work with my VZW S4. So I am just going to have to wait till the end of the year and go back and test it again.

That phone was before VZW bought the band 4 spectrum and cut the deal with the FCC. All VZW LTE phones are SIM unlocked. Any AWS capable VZW phone is SIM unlocked and can use LTE on band 4. The S4 got it with an update last year.
I am probably going to do the $30 plan soon and plan to use my VZW S4. I am not going to port my number right away in case the service in my area sucks (doubtful, live in DFW in dense surburbia).
I went out off town this weekend and went to a t-mobile store and was able to get 4g service after adding the correct APN. But it is too bad that iwireless that is in my area does not use that band yet, they are staring to upgrade to that band later this year. Until then my s4 will only get edge service.

With the announcement of the T Mobile $100 2 line unlimited everything, I'm also interested in bringing my Verizon S4 MDK boot loader phone to T Mobile, but want to do my research first-- is it as simple as signing up for T Mobile and getting one of their SIMs and then-- would I be able to flash any of the ROMs in the S4 T Mobile Dev forum or is the T Mobile S4 a completely different device? Any caveats? Would I have to LokiDoki after the flash? Would I need to flash a T Mobile specific radio too (currently on i545vrufnk1)? Or is that all just overcomplicating things? Would i be able to just adjust the APNs on my current ROM after inserting a T Mobile SIM?

Quick reply to my post and for anyone else interested-- there's a post here that talks about using a 4.4.2 T-Mobile ROM by Fenny on the a Verizon S4: http://forum.xda-developers.com/showthread.php?p=57453019 I've tried it and LTE works great, MMS works properly, phone calls work as well. I'm on the Verizon i545vruamdk bootloader and Verizon i545vrufnk1 radio. The ROM is a T-Mobile m919uvufnb4 by Fenny.
