How about the carrier where the phone came from or where you have your contract?

Last time I check this site give phone carrier network, then base on it you can guess lock status: Check samsung carrier

How to use AT&T S4 on International Network??

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]

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

Flashing a T-Mobile ROM is your only option, we can't flash other ODIN packages or else we would have used that to unlock the bootloader.

Strange boot sequence and unlock problem

I have a second hand note 3 n9005 it is verry Co fusing as on boot before rom. Use to flash up o2 however it's locked to ee I recently paid for aim unlock and have to return to store as been a problem
Why would it show o2 bloat Ware but be locked to ee?
A friend said flashing new modem may help is this possible or no reply way to network unlock in UK?
Any help is much appreciated thank you

What is the model number on download mode?

The model is showing as sm-n9005
Thanks

Carriers will use a custom csc file on a stock rom which means there could be multiple carriers with the same phone and different csc files. For instance, I have a bell phone and loaded Rogers firmware on the phone but the phone remains locked to bell.
