    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?

    Important

    If you’ve got a Pre-Paid or an Upfront plan, you won’t be able to find your PUK in the My Telstra app. Contact us for help.

    If you have a post-paid mobile, you can find your PUK code in the My Telstra app.

    2. Go to Services then select your mobile service
    3. Select the More menu (three vertical dots) at the top right corner of the screen
    4. Go to View your PUK.
