Fixed Dialing - Zte Altair User Manual

Note: If you change the PIN code, please remember the new number. If you
enter the wrong PIN code 10 times in a row, the phone will lock the SIM card
and prompt you to enter a PUK code to unlock it.
PIN2 and PUK codes
PIN2 codes are used for some settings. To change the PIN2 code, use the
same procedure as outlined above for the PIN code.
A PUK code is the unlock code for the SIM card. This code can be used to
unlock a SIM card when you have entered the wrong PIN code 10 times.
When you enter the correct PUK code, you will be able to re-assign a new PIN
code, after which the SIM card can be used normally. Contact your service
provider for more information.
A PUK code can only be entered 10 times in a row. If you enter the wrong PUK
code more than 10 times, the SIM card will be locked indefinitely. Contact Aio
Customer Care at 1-855-246-2461 for more information.
Note: If a PUK code is supplied with your SIM card, store it securely.
