Whenever I try to enable call barring to prevent international calls (turns out I made an accidental call to Canada thinking it was just another state) I get the error message in the title. It asks for a password (and uses that word, not PIN or PIN2) and restricts entry to numbers only, and only four digits long. No generic PINs or specific PINs I've set work. I've even locked my PIN2 and unlocked it with a PUK2 code from T-Mobile so I could reset it to a PIN of my own and that number doesn't work, either, even after giving it a few hours to settle in because the rep online said it could take an hour or two.
Anyone know how to enable call barring so I can enable or disable international calls whenever I want? I don't want to have to call T-Mobile each time.
