Can somebody please help me? I am essentially having the same problem as most other posters. I had two phones on my account both Galaxy S7s that were unlocked. Problem is one worked with the new carrier and mine (after putting in the new sim) reads invalid sim and under the UICC Unlock setting states that the phone is locked to Sprint Sims only. I have spoken to customer service in the neighborhood of 6-7 times and no one has been of any use. I this point I am extremely upset and unable to use the phone I paid for.
i told them i do not have the original sim. they said ok. s7 has been connected to wifi for 2 days. still says locked to sprint only. it reads my sim as an at&t sim but wont let me access their network. why? i have spent another 2 hours on the phone today just for some guy to say, "hey i will call you monday".
