So I've read thru many threads on here and found people that seemed to have flashed their tmobile ROM onto their AT&T device in order to get proper 3G+ speeds.
1) Does this actually work?
2) Is it better to flash the other way (if possible, AT&T rom onto Tmobile) in order to get maximum service from both phones? What is the best/better phone to purchase for future LTE future proofing?

I am also on the t-mobile Q&A section looking for answers... the best phone for future proof and LTE is the AT&T version... no doubt... now... I am waiting for an AT&T Stock Rooted WITH MODEM included in the same flash zip before I begin testing myself... I already ordered from ebay a dual sim card adapter for the Note 2, and the Note 2 is already unlocked... so... any news on this would be great...
I just flashed Tmobile Jedi X3 with my att note 2...all working perfectly....the steps I took was just to flash rom and one of our att kernels and youll be fine...didnt have to flash modem....just put my straight talk apn in done....Everything perfect...btw jedi X3 is super fast....:good::highfive:

Sounds like you might be in the same boat as me. Anxious to get a Note II but not sure which network to commit to with it. Your comment about needing to get a TMo ROM to get "proper 3G+ speeds" is disconcerting. It also pushes me a bit towards TMo since it's got the LTE radio promised for future update.
What exactly is wrong with the stock device's 3G+ speeds on AT&T?
Where I live and work (Los Angeles area - San Fernando & Santa Clarita valleys), LTE's not activated, and no firm date when it will come our way. AT&T's HSPA data speeds here aren't anything to write home about, but neither are TMo's when I tested one of their devices in the local shop. My AT&T phone is lucky to get 4Mb/s down, 0.2Mb/s up, and generally only about 2-3Mb/s down. The TMo Galaxy SIII I tested got 4MB/s down. Hard numbers to swallow when I've got an SIII on VZW LTE pulling down 20Mb/s in the same area.

Jedy 3 is an international rom, not T-Mobile with wifi calling... with 3.5G on T-mobile on Jedi 3? (HSPA+)

I need clarification on this. Just because the ROM flashed worked, doesn't necessarily mean the proper AWS radio's were activated to attain 4G speeds that are required on T-mobile (this is nothing to do with LTE).
Are you saying that by flashing the tmobile ROM onto your at&t note 2, you are able to attain all connections (not just Edge, but HSPA+ 4G) with your AT&T device to tmobile using AWS? I know Tmobile has begun refarming out to 4G on a different band that is compatible with more handsets, so you might just be in an area where they have already done so, which mistakes you into believing that you are actually connecting via the old school AWS Tmobile bands, when you aren't.
I really need to decide which phone I want to take the risk on - The tmobile LTE is locked apparently, doesn't seem to show as many capable bands as the AT&T version, and also, I'm not sure what to bank on in terms of there being a software vs hardware lock (Would be nice if the tmobile can be unlocked via software to fully operate on all LTE modes that the AT&T supports).
I'm actually in Canada, and would probably end up needing to purchase the Wind version in order to get what I'm looking for (since Wind operates on the same AWS frequencies as tmobile). But losing out on Bell/Rogers/Telus LTE in the process is just something I don't want to do either.
Going to have to see what can be unlocked via software on all these different phones................
I would also appreciate a response from someone if this is possible... using T-Mobile ROM and modem to work on At&t (with aws frequencies).... just like the S2 I717 mod which after flashing was working with aws frequencies....

Yes... it should... as soon as I get my dual sim card adapter for the Note 2... I will post a million results/combinations here on T-Mobile and AT&T forums... I just don't want to open the back cover 30 times a day and swap sims a bunch of times... with the adapter I just insert the 2 sim cards and done... testing all the way from that point on...

I have the SAMSUNG-SGH-I317 from AT&T, unlocked via unlock code from AT&T. No root, stock AT&T android 4.1.1. I got the t-mobile microSIM card with an unlimited talk and 2GB unlimited data plan, but I can not get tmobile 3G/4G working reliably. I get HSDPA/HSPAP/UMTS/EDGE randomly. 80% EDGE, 20% high speed between 4-8mbps down, 0.7-1.9mbps up. I am in Los Angeles, CA.
I know my SGH-I317 does not have the 1700MHz antenna needed for t-mobile 3G/4G data, but somehow I get 3G/4G 20% of the time. I have not adjusted any special settings on my phone, other than to reset the APN to default epc .tmobile .com. My guess I am getting 3G/4G via the 2100MHz antenna for download, but without the 1700MHz for fast upload, I get 0.7-1.9mbps only. But most of the time I am stuck at EDGE.
So has anyone gotten the AT&T Note II to reliably work on t-mobile 3G/4G? is there a special setting I need to enter on my phone? does flashing the t-mobile ROM on the AT&T phone solve any of the 3G/4G issue? or will I lose the unlock on my phone when I root or when I flash t-mobile ROM on my AT&T Note 2?
Any help greatly appreciated.

Hey I got a unlocked & Rooted At&t Note 2 on T-mobile running CleanRom with perfect 4g. Before I rooted my phone I changed my phones modem to T-mobiles because I only had edge. After that I have flashed several different At&t Roms and still have 4g. On speed test I get about 7-9mbs download and 2-3 mbs on upload not the best but way better than edge

I dont know...LTE for t-mobile isn't in Jacksonville FL yet. I am suppose to be going to California in a month or two and from what i heard , there is LTE in the biigger cities Im excited to find out and i'll keep you updated if i do.
I have att note 2 running clean rom with ublocked carrier on t mo. Here in la I have not see lte but we are aleay quite late getting upgrade. Most likely you will need to go to san francisco or techie area to test it

Yea your right...hey i know this has nothing to do with this thread but i want to ask you something. You have the exact set up that i am currently using.I also have an unlocked At&t Note 2 SGH-i317 on T-mobile running CleanRom SE1.5. I absoulutely love it. I like the stock look with better performance. Are you using another Kernel? And im also thinking about flashing a new Rom what would you recommend? Im kinda looking for something Similar to Clean but better battery life. Any Suggestions???

I am actually using the CleanROM 4.5 (haven't flashed 4.6.1 as I do not see much new on that ROM). I am actually using it on the stock kernel because I am not a huge flasher like many of the members here. Since Note 2 is my daily driver, I don't want to keep updating it and customize it after each ROM flashing. I like the CleanROM 4.5 since it was the way I got it and I just updated to the new version. The battery life is pretty good as I can last a day or more with moderate use.

Yea im the same way. You have an At&t note 2 too?
yep using ATT Note 2 on TMo's network.
Hey all, atm I use the stock rom, rooted for tmobile. (Stock rom isnt that bad for JB tbh.. to my surprise) However I just switched to ATT, waiting on my nano to micro adapter to come in so I can switch back to use it. Now as far as I read, I should have the 3g and 4g bands just fine, I just wont have LTE on ATT, correct? Next up, aside from using titanium backup to force uninstall TMOs software, was wondering, should I change out my rom too or is stock still cool to use for ATT?
That or what is everyone else doing if they took their S3 to ATT or tweaks that could help for network speed etc. That or apps that are good for ATT on it. Thanks.
Anyone? Or is there no tweaks or more ideal rom builds. Atm I mange to get 3-4 Mbps download speeds. Not sure how fast Iphone 5 gets.. Didnt test and dont feel like taking the sim out again tonight lol.
As suggested by the ATT S3 section of the forums, Ill put my post here too with more details on what I could be looking for.
Hello, Just changed from Tmobile to ATT. I already unlocked it, and am running it on 4G. Sad part is, download is only like 1-3 Mbps it seems. While my Iphone 5 can get close to 7 Mbps (Now this is just 4G band, NOT LTE)
So I am wondering if there are some tweaks I need to adjust in the build.prop or anything else. Atm I just use the stock rom thats rooted. (Since it seems nice enough for JB and honestly, I havent figured out which custom rom beats the stock rom 100% without losing any features.
Also noticed I cant install the ATT Visual voicemail as it claims device isnt compatible. (Which that I am sure I can use a build.prop edit for the model. Question is, which model and items do I need to adjust and to what value?)
Anyways, if anyone has some good advice about using the tmobile S3 on ATT and getting it tweaked to be the best it can be, or a rom that is perfect for switching between ATT and Tmobile (should I use my prepay tmo sim in it again) and provide high data speed. Would be great.
Oh also.. just so I know. Can I use the ROMs posted in this ATT section of XDA for the t999 tmo s3 or do I need to still only use roms from the tmo s3 section of xda? Thanks. =)

Not sure about the other stuff, but with regard to this, your phone is still a t999 no matter what carrier you are with. Hardware doesnt change, so I would recommend you stick around in the tmo section.
Some att ROMs may work, but not sure which, so if you DO want to use an att rom, I would suggest asking the dev if it will work for the t999.
Sorry I couldnt answer about the rest, im too noobish for all that
Sent from my SGH-T999 using xda app-developers app
Yea thats the trick, Seems its hard to even find that advice lol. I mean long as I dont use the international s3 roms. Just between Tmobiles and ATT. I dont know. I dont even know if its considered the same model and could use the same rom. Perk of using an ATT rom, may increase my network speed some along with being able to use their apps. Atm I cant use the ATT Visual voicemail since it says my phone isnt compatible. Which I know I could prob bypass that with the build.prop provided I knew which model to make my phone.
First of all i wanna say, you all do an amazing job with all of this. So ive been looking around the forums and i cant find an answer to my question, so i will post and wait for replay. i have the at&t version (i747) of the gs3 and had updated to 4.1.1 via kies. early march i found a post on your forums about sim/carrier unlocking and tried it out. it worked w/o any problems, so i headed to t-mobile to jump on their monthly unlimited 4g plan. installed sim and had no problems. all functions work: calls, im, sms, mms, data (edge, 3g, and HSPA+), everything. on march 17th, i decided to try out a custom rom. i odin rooted my phone with cwm then tried out [ROM][4.2.2][STABLE] LiquidSmooth v2.1 - d2att - 3|16|13. works absolutely fine. sorry for the long wind but i just want to make sure i give all info before posting my question as i may prevent unness replies. having an at&t phone using tmobile as the carrier, can i use roms intended for t-mobile only, or do i have to stick to at&t/multi-carrier roms only?
Honestly making sure you have a T-Mobile put in is all that matters. Other than that they are fairly interchangeable.

I have been making roms, from Canada claro i747m, and tmobile t999 and att 747 and they all work as they should. no problems at all, using stock att modem i747ucdlk3 without any issues...
all I did was change the build prop to represent d2att..
I have simplemobile which is a tmobile company.. except for now I just used up my 4g.. I usually get 3g, but for some reason im getting an E which speed is like 2g edge.. slow at the moment.. never seen that in 3 months..
check my signature, for my roms... they r all stock original roms..
I'm in the same situation as the op. I have at&t i747 unlocked to use with tmobile. My question is, if I flash a multi-rom What carrier do I choose during the aroma install? do I pick tmobile because thats what network im using now or do I pick at&t because its originally an at&t device? any help or advice would be greatly aprecciated.
during the install of liquidsmooth i chose att since i do have the branded phone. i cant use the lte settings for network cause tmob doesnt have their lte out yet (soon to drop), but i am wanting to try the tmobile install and see if i get any difference in data speeds. other than that, liquidsmooth is a pretty solid build. this is the only rom i have tried on my gs3 so far. id like to try others to maybe help give feedback for builders, i just wasnt sure if i could use tmobile or had to stick to att roms. thanks for the info.
on a side note, the rom unlocked a 1080p video record and i like showing ppl the OC ability. 1.9Ghz. YAY!!!
when I first made my Canada Claro rom d2can everything worked out the box. the only thing was it was showing me info of I747m, everything was still working, same when I made my tmobile rom, it was showing d2tmo, everything worked out the box, just that it showed me info of T999, so both of the roms worked, all I did was change the build prop to represent d2att ATT info..
So the answer is yes, u can use other roms... just be careful not to install the modem. I never changed that. I remove them from the rom.
Danger,, I tried making the international GT I9300 and removed the modem, changed the build prop.. almost bricked my phone, played with it to try to make it work, It would hang and sometimes not boot up... so stay away from international one.
so if u try Canada or tmobile u should be safe, its the same phones... or if someone post roms that are ported to att i747.
I am using i747 for T-Mobile.
Can somebody tell me what ROM i should use in order to get WIFI Calling on it ?
Thank you.
I've switched from ATT to T-Mobile.
I've been running the nightly build on my ATT SGH-i747, I've unlocked the phone and can receive calls etc on the device with the new T-Mobile sim. At the moment I'm not getting any 4g, but I've yet to confirm that is a build issue as I saw this once before in previous updates.
Looking at the get.cm page there are builds for the T-Mobile S3, at this point should I use that build on my device or are they close enough that no issues will arise if I continue updating the ATT builds? Just don't want to nuke the device, because then I would be stuck with the z10 that I plan on returning tomorrow

I have simplemobile which is a tmobile company.. for the past 4 or 5 days, I was stuck on E which stands for Edge which is 2g.. but when I went downtown tampa, fl I had 4g..
same problem with my wifes S2 stuck on E..
I tried several roms I made with the same problem. the last rom I did was a tmobile rom which u will see on my signature..
so on my phone the S3 using the tmobile rom, and my wifes S2 phone I did the following, which wasn't on the stock ATT rom.
settings/wireless and network/more settings/mobile networks/network mode/ use WCDMA ONLY.. stays on 4g for me all the time...

Thanks! I thought that was going to be a settings option, just couldn't remember where it was.
Also I answered my own question by backing up and attempting to load the d2tmo ROM, it wouldn't load due to device type error. So I guess that's that

I have the S3 ATT version.. I tried the d2tmo on my phone 1st, it worked just fine... I then changed the build prop and changed everything that said d2tmo to d2att so my phone thinks it a ATT phone..
both worked just the same...
but remember the ATT original build from 11 2012 doesn't have the setting for WCDMA... that's how I got it to work from tmobile ver...
Restoring a nandroid from my T999 did the trick for me, works just like it. Wifi calling even works perfectly.

Recently picked up an I747 second-hand, and have since unlocked it to put a T-Mobile SIM in it, rooted it, and flashed a number of ROMS - but what I'm looking for is a ROM with support for T-Mobile wifi calling. Is there such a beast? I've heard TouchWiz roms are my best bet, so I blindly installed S3RX from over there on the Development forum - no such luck; it works, but I see no Wi-Fi calling option.
Am I out of luck? I live out on the coast where T-Mobile has next to no coverage, and wi-fi calling seems like my best bet at home. I've done some searching, but no dice thus far. Since S3 roms seem to be being homogenized into a universal "d2lte" device, should I be looking over on the T-Mobile dev forums for roms based on T-Mobile stock?
