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 indenitely. 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.
