Unlocking an O2 mobile to use on a different network

Unlocking an O2 mobile to use on a different network

Pay Monthly customers

If you’re on a Pay Monthly tariff, you can ask us to unlock your phone or tablet at any time, for free.  

This doesn’t affect your contract though – you’ll still need to see out the rest of it, depending on your device and tariff.

The only way to unlock your phone or tablet is by using My O2 online or via the main menu of the My O2 app. Once it’s unlocked, we’ll text you to let you know.

If you’ve got an iPhone or an iPad, you’ll need to connect it to iTunes once you’ve put a non-O2 sim into the device. iTunes will then tell you the phone or tablet is unlocked.

For all other phones and tablets, you’ll get a text from us with an unlocking code. Simply enter this into your device and follow the instructions.

Pay As You Go customers

If you’re on Pay As You Go, your O2 phone or tablet can be unlocked at any time, for free.

The quickest and easiest way to unlock your phone is by using My O2 online or via the main menu of the My O2 app. Not registered for My O2? Sign up now. We’ll text you to let you know when we’ve unlocked your phone.

If you’ve got an iPhone or iPad, you’ll need to connect it to iTunes once you’ve put a non-O2 sim into the device. iTunes will then tell you the phone is unlocked.

For all other phones and tablets, you’ll get a text from us with an unlocking code. Simply enter this into your device and follow the instructions.

Business customers

If you’re the main account holder you can ask for your devices to be unlocked at any time, on us.

Don’t forget you’ll still need to see out the minimum term of your contract, even if you place a non-O2 sim into your phone.

To ask for your phone to be unlocked, you’ll need to complete our online form.

If we accept your request, we’ll email you within seven days with the details on how to unlock your phone.

If you’ve asked us to unlock an iPhone or iPad, you’ll need to put a non-O2 sim into the device and connect it to iTunes. iTunes will then tell you the phone or tablet is unlocked.
