Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before [emoji3] [emoji2]

Hey guys, so I bought recently a galaxy s5 in USA (I'm not living in USA).
The Galaxy s5 I bought is a Verizon's version, I think its called CDMA.
so anyway, I wanted to boot this phone and install a different ROM on it.
Right now its unlocked and I can use my own SIM card and it works just fine but I'm worried about the fact that I don't know how is unlocking works.. I don't want to install a different ROM and then my SIM won't work..
If something like this might happen, how can I make sure about it?
Thank you.
Anyone....?
i have an AT&T s5 and am also wondering the same question!
No answer =/
Understand that AT&T has locked bootloader on S5.
Can anyone tell me which model I should buy that will work on the AT&T LTE network but has an unlocked bootloader and can be rooted ? Also understand that there seem to be several variants of S5 available like G900F G906S etc....
Anyone tell me which one to buy ? want to use AT&T but have full control on device.
Thanks
You should but the one from T-mobile it will work with AT&T but you will have to Sim unlock it and you will be able to install roms on it.

The Sgh-i337 is basically the same as the gt-i9505 EXCEPT for ATT locking the bootloader on that model.
You CAN Sim unlock it so you can insert your Sim into it. You will have to reach it a bit though. It helps if you know what firmware is installed on the phone. If it is MDB, MDL, or MF3 it would be easier to do I believe. Either way look for the threads about unlocking.
If you have NEWER firmware then there are separate threads for it, and it will more than likely need to be rooted, flash a older modem, then perform the Sim unlock from the menu. If you cannot find the correct post I can help look for it later.
Just reply back with WHAT firmware and Baseband you have installed on the phone and we should be able to help you further.
If you do have MDB or MDL firmware do NOF update it...

Thanks for reply ,I have NC1 firmware and I used Method 3 on this guide http://forum.xda-developers.com/showthread.php?t=2595457 .SUCCESS!
Could you recommend a modem I could try other than MF3 as the signal isn't that great ?

Not sure which would work best for your area. You can download and try any/all of them until you find one that works best. You can switch back and forth with no issues without worries
