Network Unlock Samsung Galaxy S4 GT19505 T-mobile UK
Few days back I took a contract from T-mobile UK and want to unlock it. I thought from the forums easily I can follow the procedure and unlock my phone but it is not happening. I'm not getting the screen of service mode where i can see UMTS so that I can follow the other steps. Can anybody please tell the code to enter the service mode window so that i can try myself. It will be a real help if you can help me otherwise I'm totally screwed up.
