Unblocking the PIN
If you enter your PIN incorrectly three times, your SIM card is
blocked. To unblock your SIM card, you must contact Sprint
Customer Service to get a PIN Unblock Code (PUK). Follow
their instructions for unblocking your SIM PIN
Important:
If you unsuccessfully enter the PUK code 10 times, your
SIM card is permanently blocked and must be replaced.
If this happens, you get a message to contact Sprint
Customer Service. Except for making emergency calls,
your phone does not function with a blocked SIM card.
