Is it possible to convert galaxy s4 I337 (att) to I337M(Bell). I used to live in US and recently moved to Canada and got Bell Mobility as my carrier. My phone is unlocked. At&t gave me unlock code, tried it and worked fine in T-mobile and other GSM carriers in India.
Now after switching I can receive calls, internet is working fine. But for some reason I can't make calls. If I dial a Canadian number it goes to some random number in USA, even though I put in correct Canadian area code.
Is Bell using different bandwidth than at&t that is causing this issue? I am wondering the possible solution would be to flash Baseband and Bootloader, to ensure it uses correct bandwidths. I want to be sure whether this is even possible.
Appreciate any suggestions.
It's not possible to flash i337m stock images on the i337. But have you checked your apn to make sure it's correct for bell?

Greetings all
Is there a way to get an unlocked SGH M919V from Videotron to work with TELUS , the phone works but not LTE and if I enable it using the enable all LTE in the phone console I lose the capability to make or receive phone calls .
Do I need to install a different firmware and if so which one.
Thanks in advance.

Hi there..
All of you masters out there. I just jumped from an iphone to s4. And got this S4-SGH M919V from WIND Canada.
I am a newbee to Android. Now I have been searching if there is a way to enable LTE in my S4. I am facing the exact same problem as my friend posted above. I have tried enabling LTE through ×#2263# command. It does show an esterik infront of LTE bands once selected butttttt I cant make calls.
Now I think this is happening because Wind model of S4 which I have does not support the LTE band frequencies...
My question is if there anyway I can flash the modem firmware from T-mobile which apparently has all the LTE bands in it????
Will that enable LTE in my S4??
P.S I have not rooted or done anything yet with the phone. Just got it unlocked through Wind mobile.
Phone details are as folows..
Wind S4.
Device name : SGH M919V
Baseband : M919VVLUAMG1.
I am currently using wind mobile sim card with 4g speed on it.
I really need this LTE enabled. Because when I put a Bell sim in my phone. It connects data with 3g. Its not showing LTE at all. And when I tried forcing LTE with bell sim inserted, the LTE works fine but I lose the calls.
I would greately appreciate any guidence here. Thank you.

the answer...
Not sure if anyone still needs the answer to this but i just figured it out WITHOUT having to flash anything to the phone... phone is 100% stock except that its unlocked... Its the SGH-M919V from WIND mobile in Canada.. I switched over to Koodo mobile and LTE wasnt working... So open the dialer and type in *#2263# and hit AUTOMATIC and make sure theres a star beside it... before this only 3G would come up... Now LTE works!!! Good luck!
I cant find a clear answer if an ATT galaxy s5 will work on tmobile ( phone is unlocked) or will it be missing some features
and also if I install a tmobile stock rom on att phone will it have the wifi calling and all the features of a t mobile phone?
im trying to buy a phone today and cant find any solid info on the internet its a bit confusing
There are lots of existing threads that ask and answer this, so your search missed those (or you didn't search).
Anyway, you can use a TMB phone on ATT without any issues. It doesn't work as well in the reverse as you want to do. The ATT model is missing several frequency bands that the TMB phone has. And ATT, unlike most carriers, also locks the bootloader.
So a (SIM unlocked) 900A phone will work on TMB but will have some gaps in coverage. In a large city with lots of redundant bands that may not be much of a problem. But you will be subject to more congestion, dropped calls and outside of large, urban centers you may even have no coverage i.e. if an area is only served by the bands your phone doesn't have.
And the locked bootloader means that you can't install a custom kernel or recovery. Although you can emulate them with the Safestrap program on an ATT handset. The best way to get the TMB apps, wifi calling, etc is to root and install a custom ROM that is 900T based or 900F based, with the TMB apps added.

I'm using an unlocked Verizon S4 on AT&T everything seems to work but mms, already called AT&T and added the correct IMEI to my number, still will not work... only small mms will send/receive.
Thanks.
Update
Installing GoldFinger worked perfectly
The phone is CDMA, AT&T uses GSM. Different bands and all that. I would think that's the problem.

Check your APN to see if it is correct for ATT, do a google search for ATT APN and you should be able to find it. If not I can post up some screenshots for you.
If the APN is correct then it "may" be that the Verizon phone cannot receive due to wrong frequency bands?
Hi I was wondering if anyone had tried to activate a T-Mobile S4 variant on Sprint networks . I read where one will need a valid ESn Number . I realize that Sprint uses different bands for their voice text and LTE data then T-Mobile does . Would I need to install a Sprint variant S4 rom to solve this issue with the cellular modem radio . Any help appreciated
Late reply here. You have issues that will make it very difficult for you to accomplish what you're trying to do.
1. You can't install a Sprint ROM on a T-Mobile device. Odin will check to determine whether the ROM is correct for the device, and if it isn't, will refuse to install it.
2. Installing a Sprint baseband on a T-Mobile device, if it were possible, would render the wireless capabilities of the device useless until the T-Mobile baseband were restored.
3. You'd need to convert the IMEI to an ESN. This is perhaps the easiest thing to do since the ESN is the IMEI, but ignoring the very last digit in the IMEI (the check digit).
4. Sprint is extremely reluctant to activate non-Sprint phones on their network, to the point of outright refusal in some cases.
I personally recommend switching from Sprint to T-Mobile or an MVNO using T-Mobile if you really want to use this device. Not only is the service better than Sprint, you don't have any hoops to jump through in order to get the S4 working on the network. If you insist upon using Sprint, find a different device.
I recently bought used Sprint Samsung Galaxy S7. It turned out the phone is locked to Sprint and is on bootloader v5. I called Sprint but they refused to unlock it even though it is paid in full because I am not the owner of the account that phone is associated with. I bought it from an electronics recycling company, so they cannot help with this. I would like to use it with a gsm carrier, like ATT or T-Mobile. What are my options here? Can the phone be unlocked by third-party? Even if unlocked, can the necessary bands and other settings be made available? Any hacks that trip KNOX are unfortunately not acceptable in my case (it seems putting U firmware with BL5 will trip KNOX).
IMEIGURUS.COM should have a carrier unlock for you. not saying its free.
That is fine but after it is unlocked would I be able to use it with t-mobile or att without issues? I read a lot about LTE frequencies locked, missing menus to set APNs, etc.
It is fine if the answer to my original question is to simply get rid of the phone. I am already considering this, as I naively thought that all it would need is a call to Sprint to unlock it and then flashing the U firmware.

There is a thread here about unlocking additional LTE bands.
