Hi,
I have an AT&T S4 that I got unlocked from AT&T and I have been using it for a few months on UK's Three network with no problems. However, I am on a trip to Portugal for a couple weeks and was hoping to get a SIM card with data for use while here. However, with both Vodafone and NOS I was unable to have the phone connect to the mobile network and get data. I tried changing/checking the APN but nothing has worked. Any advice for me? My phone isn't rooted but I can root it if needed. Thanks for the help.

I bought a galaxy s4 from china that was supposedly sim unlocked, however when I put in the sim, the network provider shows up but either there's no service or I can't register on the network. I've googled for days on how to unlock this phone from rooting or flashing to i9505 to no avail.

Hi Guys and Girls..lol.
I have AT&T Note3 that is under contract and I want to be able to use it in India during my month long visit.
I have the phone rooted, with safetrap (Latest version) and ROM from here.
I also installed the Region Lock Away app (got it from here) and it sucessfully did its job and rebooted.
I still dont know if this phone is ready to be used in India.
I do not have any other SIIM to test it.
Would anyone have any idea as to how I can test the phone without SIM CARD to know if its unlocked to take any other SIM cARD?
What would I do to make it ready for use in INDIA.
Thanks for your time and help.

Bump!!..anyone?
Hi, friend of mine gave me a Note 3 which was locked to Wind mobile before.
The phone is now unlocked and can work with Rogers, Fido, Telus, Bell and T-mobile.
The problem I have now is whenever I put back the Wind card in, I can't have it to register to wind network.
I even tried to update it to the latest stock firmware OTA to 4.42 now and it still doing the same thing.
Is there anything I can do to make it work on Wind network again?
I suspect the phone is not running on 1700mhz.
Is there a way to find out?
Hello,i'm new at that forum.Few weeks ago i bought s7 (sprint) from ebay and the firmware model is G930PVPU6BRD2 which has bootloader 6 and no other firmware is installing at that phone,otherwise it is bricked (i tried 4 or 5 firmware and root methods but no good result) and if i install correct (G930PVPU6BRD2) software it is working.I live in Georgia and there are 3 mobile operator which provides LTE bands and my phone refuses sim (it says "Invalid Sim").

P.S. my friend also bought s7 edge (sprint) from ebay and give it to technical,which what i think unlock LTE bans and firmware is still G935PVPU6BRD2 with sprint built in apps but system message is still activation required,but phone works great with calling and LTE.He told me that technical firstly downgrade phone and than upgrade it (he is noob at phones and actually don't know which steps technical done to unlock sim and cann't tell me whole process).
Please help if anyone tried some working method for that problem!
