Forgotten PIN or Need Your PUK Code?

Summary

If you enter your mobile PIN incorrectly three times, your SIM card will lock and you’ll be asked to enter a PUK code.

Your PUK (Personal Unlocking Key) is an 8-digit security code used to unlock your SIM card and regain access to your mobile service.

What Is a PUK Code?

A PUK code is a unique 8-digit code linked to your SIM card.

You may need it if:

• Your SIM becomes locked
• Your PIN has been entered incorrectly multiple times
• Your phone displays messages such as:
  • “SIM blocked”
  • “Enter PUK code”
  • “PIN blocked”
