The PIN code
The PIN code protects the SIM card from unauthorized access. The PIN code
can be 4 to 8 digits in length. After three successive incorrect entries the
PIN code is blocked and you’ll be asked to enter the personal unblocking
key (PUK) code.
Note: Get the original PIN code from your wireless provider.
PIN CODE REQUEST
Enable your phone to request the PIN code upon power-up. This provides
extra security in case your phone is lost or stolen.
