Every time I either turn my phone off or it dies from a dead battery, once I turn my phone back on. It keeps asking me for the my sim PUK passcode. I've already spoke with tec support and they were able to give me the code yesterday. Today I'm locked out. does anyone know where I'd find that code without having to call or drive over to the wireless store? At least this time I'll right it down and keep it on hand.
