Restoring a SIM card that has been locked out
If you enter the wrong PIN more times than the maximum number of
attempts allowed, your SIM card will become "PUK-locked."
You need a PUK code to restore access to your SIM card. You can
get this code by calling Verizon Wireless customer service.
1. On the Phone dialer screen, enter the PUK code, and then tap enter.
