Trying to unlock phone


I have a Samsung Galaxy S7 that is fully paid off, and from an account in good standing. Yet I cannot unlock the device to accept other SIM cards. I have set the phone to factory defaults and when I go to UICC unlock, it errors out with an internal error 407.


Please help, this phone was unlocked before but after a factory reset, it locked it again to Sprint SIMS again.
