Pin And Puk; Locking The Keypad - Huawei G6620 User Manual

PIN and PUK

The personal identification number (PIN) protects your SIM card from
unauthorized use. The PIN unblocking key (PUK) is used to unlock
the blocked PIN. Both the PIN and the PUK are provided with the
SIM card. For details, contact your service provider.
For your phone, SIM1 and SIM2 PIN codes are configured separately.
To enable the PIN lock function, do as follows:
In standby mode, select Menu > Settings, press
1.
(Options), select Go to to access the menu, then select Security
settings > SIM1/SIM2 security settings > SIM1/SIM2 lock.
Input the PIN code, and then press
2.
If you enter wrong PINs for a specified number of times consecutively,
the phone asks you to enter the PUK.
If you enter wrong PUKs for a specified number of times
consecutively, the SIM card becomes permanently invalid. In that
case, contact your service provider for a new SIM card.
