Hey, I just picked up a old Panasonic EB-G520 and a Nokia 5110 at a garage sale. and they both had sim cards, charge cords and covers. I turned both of them on, and they had a PIN code on them, so I went down to the guy I got them off, and asked if he knew the PIN codes for them, he said no. I put in '1234' '0000' and '1111' but then the SIM card got locked and asks me for my PUK code. I have no idea what phone number they. The sim cards are from Telstra. (I have one working Virgin Mobile SIM card, in my Nokia 3200)
