Tmo on att lte? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a extra tmo s4 and I was wondering if I were to unlock and flash an att rom n apn'z would I still get lte speed.
And does a bad tmo imei get blocked on att too?

It will work as long as the imei isn't affected on the att side. If device was reported lost or stolen it will be blocked on both carriers I believe. If just unpaid on tmobile it sometimes works but I'm not for certain. Att Roms will work but you'll have to flash a T-Mobile or i9505 kernel I believe as most att custom Roms have loki kernels.

Thanks Febby. I'm glad u reminded me about the kernel. Probably would of bricked.
Its just an unpaid tmo phone from a family plan gone wrong.
I suppose I could use a GE rom too I hope.

Any ROM will work, such as i9505 Roms or even T-Mobile. Just add the APN for att.

Buying SG4 in VN

I'm in Vietnam for vacation, the GS4 has been released here already.Was wondering if I buy GS4 here can I later flash different modem like att or tmobile US to use on their network?
My main concerns is LTE on att and tmobile.

Most likely LTE will not work so if thats your main concern just get it in the U.S unless you dont mind being on 3g maybe H+

Sprint Galaxy s4 on Tmobile.

I never had a gsm phone so I dont know alot about world phones. On sprints community foruma there is much debate if the gs4 is a world phone. I see a sim slot my guess that it is. Anyway if I were to switch to tmobile, can this phone be used or is it completely impossible? Other countries use gsm networks only so being a world phone I would assume that it can be used with US gsm networks. Thanks.

It is a world phone but it is locked to Sprint only you can call sprint and have it unlocked for international and sprint simcards only no domestic Sims like from t-mobile and AT&T.

Okay did some research and youre correct. Invalid sim pops up when a local sim is inserted. Lets say I flash the google edition rom stock rooted. Now I know it will mess up all radio with cdma but will this bypass or does sprint have a hardware lock on the device?

Yes, it will work on tmobile for text and call when you unlocked it. For data, you need to change the apn setting to epc.tmobile.com. I am sure that you will get EDGE but not sure about 3g/4g or LTE.

That is not correct. It will work if you unlocked it. You will only get EDGE data for the time being in the US.

thanks for all but can someone put what will be the procedure in how its done and the call how it will work just fine or what? please i need to know to do it im a newbee .thanks to everyone
You can't do it, it is impossible. Sprint has US carriers blocked and there is no method to unlock to use a Sprint phone on Tmobile. So here is the steps to follow: List your Sprint phone on Ebay or Craigslist, Sell it, go buy a Tmobile S4, enjoy.

Im having difficulties rooting the S4. When I check it says its not rooted properly. Im still on MF9 and have no clue how to get it to MDC/MDL baseband. Any help? And how would you change the apn settings?

There seems to be a very dismissive attitude in this thread.
I have a Sprint HTC One and I can easily throw a T-Mobile SIM in there and get full service (sans LTE) with T-Mobile. The HSPA+ is faster than the Sprint 3G.
So while I do not have personal experience with the S4 in this fashion, I do not see why it would not be possible to get it unlocked and used on T-Mobile. (Unless Samsung/Sprint are blocking it for whatever reason)

Pisses me off free unlock method

I did the free unlock method and pop in a prepaid t- mobile micro Sim card and wile it don't prompt for an unlock code it surely don't/won't connect to internet or even show E ,4G,4G LTE at all.I have to switch to stock rooted MDL just to use the service mode *#0011# and have tried just about everything with the exception of using fastgsm.com on the account of not owning a computer. I even tried sha256 back on and inserted the T-Mobile card and enter *#0011# to repeat the process. Still no unlock code prompt either way and no real service either way.anybody can reply/pm me

Tmobile has poor coverage. Good prices, but poor coverage.
That's not the reason. OP is using an AT&T S4. Any time you use an AT&T phone on T-Mobile, all you get is 2G.

True, I'd be with them if the coverage was better.
Hmm Try to disable mobile data and reenable it . make sure your APN settings are correct. If not then you may need efs repair...
You can also try the option NV Rebuild

What?
Like I said before, any time you bring an AT&T phone to T-Mobile, all you get is 2g data. Anything you try to get better will not work. If you want better either buy a T-Mobile device or get an international version of the device. Best option in this case is to sell the AT&T phone and use that money towards a new device.

I had issues with Tmobile at my house, just sitting outside on the deck... 1 bar of EDGE. Phone calls would work 25% of the time. Data would work, but rarely.
[soapbox]
As a side note... I HATE the current state of the cell phone industry in the USA. All phones should be unlocked, penta band, and sold directly from the manufacturer. Issues like this would never come up and the prices would stay down to be competitive.

While that is very true, providers/manufacturers don't want competition. They want to own everything.

Not hardly. With AWS you can unlock all the bands so att phones can get T-Mobiles lte and att lte. Noone listens because its not true. A ton of people have reported about this. Read up on it first.

From what I can tell, it looks like the process didn't flash correctly. Restore your backup (assuming you made one) and try again. It could have been a bad download. Try re-downloading the needed files. If that still fails, try another USB port and wire if necessary. If all else fails, t-mobile sucks horribly in your area.

Different carrier besides sprint?

So my brother got a sprint s4 and wants to attempt to get service on it. Can it be flashed to metro pcs or boost?

It can be unlocked to work on Tmobile in some markets depending on what frequencies are available where you live. I am currently using my SPH-L720 on tmobile in PHX AZ . Some users have reported Net10 working and others ATT but I have never investigated this. If you want to see how it works I have compiled a guide that outlines the steps I took to make it work on Tmobile. http://forum.xda-developers.com/showthread.php?t=2530610 Also look in the International SIM unlock thread in Development and the GSM data thread in general for further tips.
Also I'm sure it can be flashed to boost you just need the PRL file to flash. Check out this thread.

Since my carrier is at&t would these roms work for me?

It's the only explanation I can come up with none of the tmobile s4 roms work for me I have the tmobile s4 but I have at&t service jw

You may have to flash your carriers kernel/modules. I don't have TMO S4, check on TMO rom thread for help/anyone running on att also. :good::good:
