If you have a positive balance in your account. you could try the lost/stolen phone trick. It seems to reset or restart plans. Or if that does not work, manually load $1 to your account. Again, another trick that resets account.
To report your phone stolen. Login to your account. Choose Plans and Add-ons tab. Then choose Lost/Stolen Phone tab. The choose Suspend Service tab. Logout. Wait few minutes. Login in and report your phone found.
