Unblock the SIM Card PIN Code
If you enter an incorrect SIM card PIN code three times in a row,
your SIM card is disabled and your phone displays the message
SIM Blocked. You need to enter a PIN unblocking key (PUK)
code, which you can obtain from your service provider.
Note: In the following key sequence, each key press must occur
within two seconds of the previous keypress.
Caution: If the unblocking attempt is tried unsuccessfully 10
times, the SIM card is permanently disabled and your phone
displays the message SIM Disabled.
