How to unlock my phone with a PUK code

Jump to:

What’s a PUK code?

Your PUK is an 8-digit code unique to your SIM card. You can use it to reset your SIM PIN and to unlock your mobile.

How to find my PUK code?

Sign in to Your Telstra Tools.
Hover over Services and select Mobile and mobile broadband.
Select the number for the device that’s currently locked. You’ll find your PUK code under your mobile number on the right hand side.

If you enter your PUK code incorrectly eight times, your SIM will become permanently blocked, and you'll need to get a new one.

What’s a SIM PIN?

Your SIM PIN is different to your PUK and your phone passcode. It’s a 4-digit number that lets you lock your SIM card to one device.

By default, your SIM PIN is the last four digits of your PUK. You can change your SIM PIN through your device settings. So if you've forgotten your SIM PIN, enter a random 4-digit number, like 0000, until you’re asked for your PUK code.
