I unlocked my galaxy S7 awhile ago ad connected it to T-mobile fine (It was previously locked to sprint). I was able to access apn settings and connect fine. I recently switched to Metro-PCS and factory reset my S7 and now whenever I try to access the apn settigs to create a metro PCS APN settings but it says "Unable to view the access point name settings. Access is restricted for the current user profile." So I cant call, text, have data, etc the SIM wont work. Why cant I change the AP settings? I was able to access them before. Any help is appreciated.
