To unblock the SIM card, dial the following sequence:
* <PUK> * <new PIN> * <new PIN> #
If the PUK is correct and the new PIN codes agree, you will hear the normal
dial tone, which indicates that the voice service is activated and that it is
possible to make phone calls. Remember the new PIN for future use.
If the PUK is incorrect or the new PIN codes do not agree, you will hear the
“PUK required” tone again. Repeat the “unblock SIM card” sequence
above.
Note: If ten attempts have been made with an incorrect PUK, the SIM
card is permanently blocked and a new SIM card is required.
Contact your service provider.
