• PUK CODES
The PUK and PUK2 codes are 4-digit to 8-digit codes that usually come from your 
service provider along with the SIM card. The PUK code unblocks a blocked PIN 
code, and the PUK2 code unblocks a blocked PIN2 code.
If you block your phone, contact your service provider. When you enter the PUK 
code given by your service provider, the phone prompts you to enter and then 
confirm a new PIN code.
