How do I unlock my Telstra Mobile?

What's in this article?

You can unlock your Telstra Pre-Paid mobile, iPhone or mobile broadband devices so they work on another network - but if you’ve had it activated on the Telstra network for less than two years, we charge:

  • $80 for devices that have never activated, or active for six months or less
  • $25 for devices activate for six months to two years

Good to know

After two years, we don’t charge an unlocking fee.

To unlock your Pre-Paid device, you’ll need to find your phone’s IMEI number.
There are four ways to locate the IMEI number for your Android device:

  • Dial *#06#.
  • In the Settings menu, select About Device > Status.
  • Look under the battery.
  • Find it printed on the original box your device came in.

There are three ways to locate the IMEI number for your iPhone:

  • Dial *#06#.
  • From the Settings menu, select General > About > IMEI.
  • On the SIM card tray or back of the phone, depending on your phone model.

Once you’ve located your phone’s IMEI number, give us a call at the Telstra Pre-Paid Unlocking Centre:

  • Dial 125 88 80 if calling from a Telstra phone.
  • Dial 13 22 00 if calling from a non-Telstra phone.
  • Dial +61 439 125 888 if calling from overseas (please note: international charges will apply).

The team will ask for your phone’s IMEI number, so they can provide instructions on how to unlock your device, and if an unlocking fee will apply.

Remember to back up your phone before you unlock it or you may lose your data.


If you’re on a post-paid plan, you can use our online iPhone unlocking tool.

You can still use the tool if you’re not a Telstra customer, but it can only unlock iPhone and iPad2 devices purchased from Telstra. The unlock tool isn’t available for Pre-Paid customers.

Your unlock request will take up to 72 hours to be processed. After 72 hours, follow the Apple unlock instructions, and update your settings to the new network.

Wait - backup before you unlock.

Back up your iPhone before you unlock it or you may lose the data on it.

  • All iPhone 5 models and above, and other iPad models on a plan, are already unlocked.
