Leave without your number 

Looking to leave Three or move to another network without your number? While we don’t want to see you go, we’re here to help. Here’s everything you need to know about cancelling your Three account.

Your options

First things first, we’d recommend checking when your contract ends. Because, if you leave us before the end of your minimum contract term, you may be charged an early termination fee. This will be equivalent to the monthly charges left during the minimum term of your agreement. You can find more information about this in our price guides. 

How to check your contract end date

Want to find out when your contract ends? Or joined us in the 30 days but changed your mind? Log into My3, or get in touch with us on 0333 338 1082 or by using Live Chat. 

Want to check for any outstanding charges on your account? You can check them by logging into My3 or texting INFO and your date of birth (DDMMYY) to 85075.  

Moving to another network without your number

If you’d like to leave us and leave your number behind, you’ll need a STAC - Service Termination Authorisation Code.  

Already requested your STAC, or are you having trouble with it? Our support page has all the information you need.

Have you got a device plan on Three Your Way with an outstanding balance?

If you cancel your Airtime plan and have an outstanding balance left on your device plan, it must still be paid in full. You can either continue paying your regular monthly payments or pay in full by bank transfer.

You can find out more in our device plan FAQs.

Looking to cancel Home Broadband? 

If you’d like to cancel your Three Home Broadband, you don’t need a STAC. You just need to give us 30 days’ notice. Or, if you want to switch to a new broadband provider, use One Touch Switch. 

Find out how to cancel Three Home Broadband.

To leave without taking your number to a new network, you can: 

  • Let us know you want to leave
  • Leave using a STAC

Letting us know you want to leave

Simply get in touch to give us 30 days’ notice. 

If you’re still within your minimum contract term, an early termination fee may be applied. You can find out more about early termination fees in our price guides. 

How to get a STAC

A STAC lets you cancel your mobile number with your current network when you change to a new one.

It’s valid for 30 days – all you need to do is give it to your new provider. They’ll do the rest.

If you don’t use your STAC, your account will stay open, and you’ll continue to be charged for your service.

You can get your STAC by:

Contacting us
Call us on 0333 338 1082 or start a Live Chat to get your STAC. 

Using My3 or the Three app

You can get your STAC on My3 or the Three app by following these steps: 

My3
  1. Log into My3
  2. Scroll to More Actions
  3. Select Leave Three
Three app
  • Log into the Three app
  • Tap Account
  • Tap Leave Three
  • Follow the on-screen instructions to get your STAC

Your STAC and its expiry date will be shown immediately. And if you’re leaving before your contract end date, your early termination fee will also be shown. 

You can check your STAC information anytime – it’ll be displayed under Manage your plan.

Sending a text

You can get your STAC by texting STAC and your date of birth (DDMMYY) to 75075.  

E.g. STAC060385

Once you’ve got your STAC, you have 30 days to give it to your new provider. They’ll arrange for your account to be switched to their network and your Three number to be closed. 

What happens if your switch fails or is delayed?

If this happens, we’d recommend contacting your new network – they’re responsible for switching your account. 

What happens if you don’t use your STAC?

If you don’t give your STAC to your new network within 30 days and haven’t asked us to close your account, it’ll stay open, and you’ll continue to be charged. 

I’ve picked a PAC but I want a STAC, what should I do?

If you’ve picked the wrong code, please get in touch with us. We’ll need to cancel the PAC before we can send a STAC to you.

If you want to cancel your Three number and move to a new network, you can. Just give us 30 days’ notice.  

If you’re still within your minimum contract term, an early termination fee may be applied. You can find out more about early termination fees in our price guides.

Your final bill

You’ll get your final bill within 38 days of closing your Three account. 

Your account will stay active until you use your STAC, and you’ll be billed for all your usage until your switch is completed. 

Find out more about your final bill.

Your outstanding charges

You can check your outstanding charges by logging into My3 or texting INFO and your date of birth (DDMMYY) to 85075. 

We’ll then send you a text with all the information you need. 

If you cancel while still within your minimum contract term, you may be charged an early termination fee. For more information, please check our price guides. 

Can I still access My3 after closing my account?

Yes, you can log into My3 to view and pay bills for up to 6 months after closing your account. 

Will my smartwatch plan still work?

If you have a smartwatch plan paired with your Airtime plan and leave us before the end of your contract, both plans will end. And if you leave before the end of your contract term, an early termination fee will be added to your final bill. 

Will I still be covered for Three Insurance?

When you leave us, any associated insurance contracts will also come to an end.
