Hello, I was recently gifted a galaxy s6 from a friend who has sprint. We requested an unlock three times and its been 2 weeks and the phone is still not unlocked. I am trying to get the phone unlocked for att use
i do have the sim and tried updating the profile and doing the sim unlock but it always fails and says failed to initialize network or something along those lines. Ive looked it up online and this model is compatible with att
Weird things happen when the phone is off the network and especially if you do a factory reset when off the network.
It will loose the provisioning of the phone that includes the UICC unlock, and since it is not linked to a line or maybe when the SIM is not in, it will not provision itself again.
As I stated before, I had a phone that was already unlocked and it was off the network, not used for about 3 years and it lost the unlock. I had to call Sprint again to push the unlock again. Once they pushed it, it took maybe a 1-2 hrs and when I did the PRL update, it took the unlock and the phone restarted.
Again, UICC never showed that it was unlocked, but I was able to get inside the APN settings and update the APN.
