Pin And Puk; Locking The Keypad - Huawei T208 User Manual

PIN and PUK

The personal identity number (PIN) protects your SIM card from
unauthorized use. The personal unlocking key (PUK) can unblock
the blocked PIN. Both PIN and PUK are delivered with the SIM card.
For details, consult your service provider.
If you enter wrong PINs for a specified number of times
consecutively, the phone asks you to enter the PUK code.
If you enter wrong PUKs for a specified number of times
consecutively, the SIM card is invalidated permanently. Contact your
service provider for a new card.
