To restore a SIM card that has been locked out

will become "PUK-locked." You need a new PUK code to restore access to the device. This code may
have been provided by your operator when you received your SIM card.
Touch
Emergency Dial
and enter the following sequence on the keypad:
* * 0 5 * [PUK code] * [new PIN] * [new PIN] #
For example, if your PUK code is 888888 and you would like to reset the PIN on your SIM card to 7777,
enter the following into Emergency Dial: **05*888888*7777*7777#
