Unlocking a Three device to use with another network

Unlocking a Three device to use on another network

Just joined Three? Check out our top tips for your first 30 days in our Welcome guide.

Select your device below to find out whether it's locked.

Note: If you bought your phone from us after 1 January 2014, it will already be unlocked.

Link to the form to unlock your device.


After you’ve requested an unlock code

We’ll send a code within 72 hours of your request, along with instructions on what to do next. If we have to get your code from a manufacturer, it can take longer. This takes a further 72 hours for Apple devices, or a further 5-7 days for non-Apple devices. This means that the process can take up to 10 days for a non-Apple device. Don’t worry if you don’t receive your code instantly. We’re working hard to get it to you as quickly as we can!


Apple devices

If you have a Three iPad you'll need to fill in the above unlock form. Any Apple phones will be unlocked if you bought them after January 2014. Or, if you’re running an older version of iOS or using an old Apple phone, fill out the form above.


Non-Apple devices

You’ll need to use our unlock form on the top of the page to unlock a Mobile Broadband device from Three. There’s a few things to know before you do:

  • If you don’t have a Three account, you’ll need to get a Three SIM to get your device unlocked. You can order a free Pay As You Go SIM online, or buy one from a Three store for £1.99. You can then use those account details to fill in the form above.
  • When filling in the form, make sure that your personal details match up exactly to the ones you see on your bill. They have to be the details of the account owner. If they don’t match, we may not be able to unlock your device.
