If you can’t remember your PIN and want to unlock your SIM card, you’ll need an 8-digit Personal Unlocking Key (PUK) code.
How do I find my PUK code?
There are two ways to find your PUK code:
- Sign in to My Telstra app
- Go to Services then select your mobile service
- Select the More menu on the top right corner of the screen and View your PUK.
