Hi, I was wondering if it was possible if there was a way to find an old phone number that isn’t in use. I need to pay an outstanding bill but have no idea what the number is to pay it . Apparently I need it . I have an account number that I set the sim card up with but that’s no help and I can not sign in to the app !
