My galaxy s7 had been working fine for almost a year and suddenly I am getting a popup saying the simcard is locked then several minutes later it says simcard invalid in the notification drawer. Not sure what happened, my device is still with a sprint plan and nothing happened between it working and not. Tried turning it on/off, cleaning the simcard, but all to no avail. Anybody have any ideas?
