1. Contact your carrier's customer support for your PUK code


2. Once the message "SIM card is PUK-Locked. Please contact Customer Care" appears on the screen, tap "Emergency Call"


3. Type in the following string: "**05*PUK*New PIN*New PIN#" (Without the quotes, and where "PUK" is the PUK code obtained by calling customer support, and where "New PIN" is your SIM card's new PIN)


4. Tap "OK" and follow any additional on-screen prompts
