Does anyone know how to unblock it?

Answer 1

The PUK  (pin unlock key) code is usually printed on the Back of the SIM pack check it out and if it isn't there then u need to call your carrier and they will give to to you after verification. Make sure not to enter the PUK code your self after 10 incorrect attempts the Sim will be permanently blocked and then u'll need to get a new one! http://en.wikipedia.org/wiki/Personal_Un...

you need to call at&t... tell them what you need, theyll ask for some info... then theyll give you the puk code... maybe save the code, just in case...
