Unlocking a Three device to use with another network.

If you have a phone or Mobile Broadband device that you've bought from us, you might want to get it unlocked so you can use it with a SIM from any network. We can unlock it for you if you pay a one-off fee of £15.32.

To unlock your Three device you'll need to get an unlock code by filling in the form below. You’ll need your device’s unique 15 digit number, called an IMEI number, to do this. See how to find your device’s IMEI number.

When filling in the form, please make sure that your personal details like your name and address match up exactly to the ones you see on your bill. If they don’t, we may not be able to unlock your device.

After filling in the form, depending on your account, we’ll either call you to take payment or add the cost to your next bill. See below for more details.

Once you’ve paid, we can often give you your unlock code straight away, but it can take up to seven days. If we can’t give it to you straight away, we'll send you an email or text with your unlock code and what to do next.

Pay Monthly.
You can unlock your device when you’re 30 days or more into your contract and once you’ve paid your first bill, or straight away if you’ve upgraded your contract.

If you’re:

in the last 110 days of your contract, we’ll just add the unlocking fee to your next bill, so we won’t call you
not yet in the last 110 days of your contract, we’ll give you a call within two working days to take the £15.32 fee using a credit or debit card. We can only take payments on cards that are registered to the account owner. You’ll see a confirmation of this payment on your next bill.
Pay As You Go.
You can unlock your device as soon as you’ve bought it from us. Once you’ve filled in the form, we’ll call you within two working days to take the £15.32 fee using a credit or debit card. We can only take payments on cards that are registered to the account owner.

Note:

Before you fill in this form, you should try another network’s SIM in your phone or Mobile Broadband device to check that it isn’t already unlocked.
If you didn’t buy your device from three.co.uk, a 3Store or by calling us, for security reasons you‘ll need to call us to send us a copy of the receipt you got when you bought your device. To talk to us about your phone, call 333 free from a Three phone or             0843 373 3333       from any other phone*. To talk to us about your Mobile Broadband device, call 500 free from a Three phone or             0843 373 0500       from any phone*.
If you want to unlock an iPhone or iPad and you have iOS 5 or above, you’ll just need to insert your new SIM once we’ve texted or emailed you. If you haven’t yet updated to iOS 5 or above, you'll need to connect your device to iTunes to get your unlock code. After we’ve called you, we'll send you a text or email to let you know when you can do this.
You should check your device and its features will work on other networks before filling in the form, as we can’t guarantee this.
Your device might still show our logo, even when you’re using a SIM card from another network. This is normal, and won’t prevent you from using the device on another network as usual.
*Calls cost 5p per minute from a BT landline, other networks may vary.
