Hey Guys,
So, I bought a AT&T LG G2 phone (I had a gift card at Best Buy- they don't carry T-Mobile). I heard that AT&T had the same towers so it's easier to work with an unlocked phone through them, so I bought it there instead from T-Mobile itself.
However, now I realized I don't have some of the features I would have on a T-mobile LG G2, such as my wifi calling, etc. Now, since the phone is unlocked (and I just got it rooted), would installing a T-Mobile rom affect my phone in any way, good or bad? Should I only use AT&T roms? How would I use T-mobile app services?
I searched google for 2 days and couldn't find anything relevant to my question. I've used this site a lot in the past year-two for rooting and such. Thank you guys in advance for continuing to support open development for android.
Wondering the same, about to switch to tmobile.

Well, seems like no one has an answer to it...
Anyway, I went ahead and bought the phone. Since I do a lot of testing and rooting myself, this was the first time working on this type. I'm glad you posted, because I would have just forgotten about it now that I've solved the question I had... However, I figure it'd help in the future in case someone is also wondering the same.
Now, with that all stated... down to the answer.
If you bought an AT&T phone, and do an unlock code to use it on another carrier (such as T-mobile since they use the same towers), the rom you MUST use are the AT&T roms... NOT the T-mobile roms. The problem is, when you buy a AT&T phone, unlock it, and root your device to use another rom, it will not be compatible with T-Mobile roms because of the image files, etc. So yes- you will be losing all the features a T-Mobile rom would have such as wi-fi calling, etc...
However, a way to go about this (and it won't work with ALL the features that comes in a T-Mobile phone/rom), is to install a AT&T rom of your choice without all the crappy AT&T bloatware that you can't even use, and go to the T-Mobile section to look for an APK version of the files. Most of the time, T-Mobile roms will also remove the bloatware, however, some developers are kind enough to provide the bloatware APK files in case users would like to have certain one of them features, such as WiFi Calling.
So, that's how I did it, and it's working good.
PS- One last thing, you may have trouble going on the internet or playstore when you're unlocked to a different carrier. All you need to do is find the APN settings for your carrier. So in this case, I bought an AT&T phone, bought unlock code to use on my carrier T-Mobile, and got the T-Mobile APN settings set up, reboot, and I get all my 4G data, etc. You can get this by calling T-Mobile. Just say, you bought an unlocked phone and can't access data, internet, etc, and was told to set up a APN. Or, you can use google. :good:

So, would I be correct in stating that you will only get 4G in areas where it is offered @ 1900 MHz? What about 2100 MHz? Otherwise you will only get 3G HSPA+? As you can tell I'm a bit confused about compatibility between networks. According to wikipedia they will be doing away with 1900 MHz 4G by 2015. I'm trying to decide if it's worth buying an AT&T or Verizon phone to use on the T-Mobile pre-paid network because it seems the T-Mobile phones are not getting very much development.

hey johnny, so you were able to get wifi calling feature on at&t branded lg g2 unlocked?
AT&T phone switch to T mobile Wifi calling do not work

Bought phone from ebay, it is an AT&T phone unlocked and want to use for T-mobile./ With T-mobile network I have to use wifi calling features in order to use in the house.
Could you please explain me how and how much it cost to get wifi calling feature in LG G2 ?
Ok,... a NOOB question.. (ok.. three questions) (and yes, I have looked around, and I did not see answers to my question… or i was too dim to understand it….. :/ )
Question 1)
I switched from AT&T to T-Mobile. my Note 3 is is unlocked, and rooted.
This is probably a silly question, but When I look at “ROMS” and “MODS” for my phone, should I be looking for an “AT&T “ phone? or a T-MOBILE” ?? is there any actual HARDWARE difference?
I have a SM-N900A (branded AT&T) … does that mean I can not use ROMS that are for the T-Mobile note 3s? or do I have to only use ROMS that are for the AT&T note 3?
Should I just sell my AT&T note 3, and buy a T-Mobile Note 3 ??
I would like to get rid of the AT&T bloatware… especially since I am no longer on their network.
I am not trying to go over the top with my phone, and I would like to be able keep the s-pen features (but I have to admit, I still need to LEARN how to use it better!)
Question 2)
I just tried to use my hotspot on my Note3, and I am gettingan "invalad sim" error...
I am guessing that I do nto have enough of the AT&T stuff out of it?
Question 3)
Another “feature” that I would like, (maybe a second question/thread?) if about tethering.. I have unlimited data on my phone, but as I understand it, they will only allow 2gigs as a hotspot. I think I read somewhere that some ROMS combine the two…
Thank you for any advice…
Danny
Okay, I can help you with a few of your questions...
Q1. Since your phone (the service provider doesn't matter, the hardware does) is ATT, you will need to get your Roms and such from the ATT area.
ATT, in all their ridiculous glory, locked the bootloader on our phones, and thus we have to SafeStrap in order to use roms.
It's a little wonky, but it's almost as good. Our development is growing and more roms are getting ported over every day.
But if you want more control over your device and can afford it, I would personally recommend to switch to a TMo device.
As for removing bloatware, most of the roms are pre slimmed, and you can fix the rest by freezing apps with TiBu. And you can still do that without losing the TouchWiz and SPen functions.
Q2. The Invalid sim issue is likely because you have a TMo sim card in ATT software. There's a Tether Provisioning app that can be frozen to prevent that.
Q3. I'm not too sure how TMo handles it's Tethering monitoring. You'll have to ask that in the TMo note forum.
I hope I could help you at all. =D

Thank you for the help!!
I have decided to buy myself a T-Mobile Note 3, and sell my AT&T version...
I had rooted my (using Kingo) about a month ago, to fix the GPS driver problem... But that was ALL I did, after rooting it... and I think this week, AT&T sent out an update (mandatory... cause I never saw it!)... which not only broke my "root" ... but broke my GPS again as well.
So now I say good bye to my brand new, with the EXTRA insuarance plan from Best Buy phone, and start looking for a used Note 3 that is not bootloader locked
AVOID AT&T

Hi folks,
Sorry for the somewhat cryptic title. My question is simple:
Can I just buy a non-ATT/Verizon S4 without locked bootloader, ROM it up with any ROM I like without having to stick to safestrap-compatible ones, then apply the I337 build.prop APN flash, and have it work on ATT and identify itself to the Google Play store as an I337?
The reason I ask is I'm getting tired of the limitations on my I337 for use with various ROMs, and it might be worth it for me to buy an unlocked variant of the S4 on Swappa, then sell mine off. Sure, it would cost a few bucks, but then I could play with any ROM I want.
I just want to make sure that I'll be able to download the specific Apps I use from ATT etc. that seem to require the I337 model...
Am I missing anything?
Marc
I haven't even researched that. But, Verizon is CDMA. Maybe an unlocked TMobile phone would work. I know you can run their roms on att S4.
Right. I was looking at a T-Mobile device most likely, or an international unlocked version.
I understand the challenges working with Verizon devices... I just returned to ATT from Verizon and had to give up my RAZR MAXX HD due to poor compatibility between the networks.
But, if I understand correctly, I can get a T-Mobile or pretty much any other carrier phone with bootloader unlocked (other than Verizon, which wouldn't be unlocked and is CDMA-specific), and it should work on ATT once the APN info is entered. I'm just looking for explicit confirmation it works, and that the phone can pretend to be an I337 so my software will install properly...
Thanks all!
Marc
not sure on specifics as i haven't tried. i know some here have and will reply--:good:

The rom of 337 might work on other variants; however, if you ever want to flash an rom, the pure samsung rom of I9505 might be a better choice; And also, if you buy a non-att variant s4, you might loose 4G data connection, even 3G, because they are simply not compatible with att network (hardware limitation), so please be careful before you make the buy; The other question, by now, I couldn't find a way to 'cheat' google play to identify a phone to att i337. If you really like those apps from att, you can always download them from other app sources other from google play.
Godd luck!

Thanks Wzhao.
My intent would be to be able to flash non-Samsung ROMS (like AOSP etc.), non-touchwiz ROMs.
And definitely I would have to buy a phone with ATT-style hardware in terms of antennas/frequency. I believe the T-Mobile ones meet this requirement but it's unclear whether I would need to get the phone SIM-unlocked to use it on ATT.
As for identifying a phone as the ATT I337: My experience using Hyperdrive (briefly) was that it identified the phone as a Verizon phone... Google play wouldn't let me install apps that were ATT specific. I believe that flashing the ATT build.prop settings fix this, but doing so messed up Hyperdrive because it interfered with the Hyperdrive Tweaks utility. There are several build.prop settings that identify the phone... the simplest of them SHG-I337 in some particular location isn't enough, but there's a hidden identifier and several others that can be set.
If you are interested in testing it, you can flash the ATT build.prop found here:
http://forum.xda-developers.com/showpost.php?p=51112381&postcount=9
which links to here: http://d-h.st/6tN
I believe it sets all the right things, because flashing it over GoldenEye makes the phone recognized by Google Play for ATT apps. I'd be interested to hear experiences of someone using a T-Mobile or other variant S4, and if it works as well on that hardware...
Marc
Hey guys. I have and Unlocked and rooted i9505 S4 (at&t branded), currently running the Goldeneye rom. I recently switched to T-mobile and wanted to make use of their wifi-calling feature but even after installing the t-mobile sim card, I dont see an option for wifi calling anywhere.
can anyone suggest a way I can get wifi-calling on my unlocked/rooted at&t branded s4? thanks!
I think you might need to take it to T-Mobile store. From my understanding, it is only for SGH-M919. AT&T phones are not compatible, even if you switch carriers. You may have to flash a T-Mobile Touchwiz rom, not sure. If anyone thinks I'm wrong, feel free to correct me. :cyclops:

Thx for the reply rootnerd! yea thats the problem i'm having... I read that some people got it working with a flashed a T-mobile rom while others said they couldn't. So I was trying to see if anyone could shed some light as to which T-mobile roms with the wifi calling feature could be flashed via safestrap on an at&t phone, because I don't really want to buy a new phone from t-mo just yet

Yeah this is where AT&T users would know the answer. I currently have a T-Mobile S4 but I really don't think it's worth keeping Touchwiz just for WiFi calling. But everyone has there own perspective.
I'm kind of newb at this S7 stuff, I'm more of an HTC guy. Yesterday, I bought an unlocked G930P (sprint) and am not sure, but think I learned that normally, people don't change out the ROMs to use a different carrier, they simply unlock the phone and live with the old carrier's bloatware. I started reading up, and first learned that TWRP apparently isn't available on a Snapdragon processor, so the G930A, G930P, etc, aren't candidates for TWRP. At first, I was kind of dismayed. Then, I found the G930U ROM and on a whim, I tried punting the G930U ROM to the G930P. I bought the phone off craigslist, and he said he didn't know where HE got it from, but it was unlocked. Anyhow, the phone took the rom without a hitch and now it looks like a U model...
My goal: Go with T-Mobile. Use Wi-Fi calling. Eventually have Nougat. Remove bloatware, but possibly keep some nice T-Mobile add-ons, if any, because I don't have their service yet (I hated ATT's crapload of stuff). Note this isn't specifically a "TMobile" question, substitute your carrier of choice for the questions...
Get to the damned question, you say? Ok, here goes:
1. I'm not going to ask any "do these bands work" when moving from a P model to T mobile. You guys seem to fight about that stuff until you can't type any longer. I'm going to assume what whatever bands work, that's what I get. Unless I get a T-Mobile specific phone.
2. But I will ask this: do the over the air bands it uses depend on the baseband ROM that is on the device? This is something I can't figure out.
3. I heard T-Mobile uses an updated boot kernel (3.0?) and ATT & others use an older boot kernel, and that if I move to T-Mobile boot kernel, I can't go back to any of the older ones. This process I seriously don't understand. Can I run a T-Mobile OS (or any OS) while using an older boot kernel ROM? I would think NO, right?
4. I don't like all of Carrier X's bloatware. I'd rather use a stripped down, cleaner ROM. I guess there are apps for that, but is it cleaner to do it with a stripped down generic ROM that I see floating around?
6. Speaking of ROM's - I saw a lot of Xetheros or whatever ROM's floating around, but it seems like there aren't any for the snapdragon-based ones. Is this true? The posts on this site don't really talk much about the snapdragon-based phones and why there aren't any ROMs for them, and why it won't work, and what, if anything, is being done to get around this. I guess the G930U is Samsung's answer to that, and allows fooling around with roms, but will the other phones ever be actually rom-able, or should I ditch this G930P and actually buy a G930U? Now that my phone THINKS it's a G930U, did that get me around some weird barrier and NOW I can update other funky roms intended for a G930U?
I'm considering selling the G7 I just got and going from a G930F (now that I'm a bit wiser). Any common sense why not to do that? I already HAVE an ATT G7 (not the sprint one I just bought), but it has a "bad signal". It gets only about 1 bar indoors, on a good day. I took it to a repair facility and they said, "nothing wrong with the antenna, it's your mainboard, don't bother just buy a new phone". Anybody have any advice on that?
thanks

All U.S. models are built the exact same and will all accept each others firmware if done right , so any unlocked s7 you put the U firmware will essentially be a g930u other than the number stamped on the back , I dont believe the U firmware supports wifi calling or VOLTE , There is a t-mobile nougat firmware floating around if you want to try that , your att g7 if it has a hardware issue should be under warranty but if your using it with a different carrier I would flash the appropriate firmware to it and see if that fixes you signal issue and if not put it back to stock and call Samsung , as far as switching from the international model , Well i bought a international edge as soon as they release and it took a crap on me within 4 months and I was unable to warranty it , that was my only issue with using a international model but also i dont think you can get wifi calling on those either . hope that helps
edit* and yes the bands are dictated by the rom , U firmware opens all of them otherwise carrier roms unlock specific , and T-mobile nougat dowgrade back to MM will be dictated by the baseband , I know the Sprint nougat can be downgraded but not T-mobile for sure

I don't believe those features are supported on AT&T (probably at AT&T's own request). Perhaps that might change in the Nougat version but I wouldn't bet on it.
