Important info

We’ll be doing some system updates between Saturday 18th and Sunday 19th May to improve the service we provide. We expect these updates to commence at 6pm on Saturday and complete at 12pm on Sunday.

You’ll still be able to call, text and use your data as usual, but you won’t be able to request a PAC, STAC or Switching Information during this time. Please try again after 12pm on Sunday.

We’re sorry for any inconvenience.

More information about leaving Three

Why Three?

If you want to leave, don't forget that there's some great reasons to stay with us. It's not too late to change your mind.

Ready to move on from Three?

Leaving us doesn't have to be painful, and we've got all the info you need right here. You can do everything easily online, through a text message or by giving us a call.

Your outstanding charges

Whatever you choose to do with your Three number, you'll still have to make sure you pay any final charges or settle an outstanding balance with us.

Your outstanding amount includes any discounts or charges. And just so you know, if you're a Pay Monthly customer, you'll also receive a final bill from us once you've left, which acts as a confirmation of the cancellation.

If you decide to leave us within your minimum contract period, you may be charged a cancellation fee to cancel your contract early.

This will be equivalent to the total of the monthly charges remaining during the minimum term of your agreement, minus a variable discount. From 14 December 2020, the discount will decrease from 20% to 3%. This is due to a change in the VAT payable by Three on cancellation fees.

If you’ve got a device plan on Three Your Way and cancel your Airtime plan, you'll need to continue paying off your device until the outstanding balance is paid.

You can settle your outstanding balance at any time via bank transfer. You’ll also no longer be able to log into your account once you’ve cancelled your Airtime plan. For more info, see our Device plan FAQs.

How to see your outstanding charges

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

Once you've requested your outstanding charges, we'll send you a text immediately with all the info you need, including the code.

Pay As You Go customers

If you’re a Pay As You Go customer, any remaining credit will be confirmed when you request a PAC or STAC code, or when you ask for your balance.

Once the transfer to your new provider is complete, contact us to get a refund for any remaining credit balance and unused Data Packs or Add-ons.

Leaving Three with your number

If you want to take your number with you when you leave Three, you'll need a PAC code. Give this to your new provider and they'll transfer your Three number over to their network.

A PAC code (Porting Authorisation Code) allows you to take your old number with you when you change service providers.

If you don't use your PAC code, your Three account will remain open, and you'll continue to be charged for your service.

There's a few different ways you can request your PAC from us.

Contact us

You can get your PAC by getting in touch with us on 0333 338 1082 or by using Live Chat.

We’ll guide you through the process, giving you the key information, and answering your questions.


Alternatively, you can get your PAC by logging into My3.

  1. Log into My3
  2. Scroll down the home page, select More Actions
  3. Select Leave Three

We'll provide a PAC immediately along with important information. If you're leaving before your contract ends, you'll be able to view any early termination charges. 

Text message

If you’ve only one number with us you can get your PAC via text. If you’ve 2 or more numbers, you’ll need to contact us or request your PAC via My3.

To get your PAC, text PAC and your date of birth (DDMMYY) to 65075.

For example: PAC06031985

We’ll reply with your PAC and important information. If you’re leaving before your contract ends, the text will include any early termination charges. 

Closing down your Three number

If you’re leaving Three and don’t want to keep your number, you'll need a STAC code instead.  
A STAC code (Service Termination Authorisation code) allows you to cancel your mobile number with your previous supplier when you change networks. 
Once you've got your STAC it's valid for 30 days. All you need to do is give this to your new provider and they'll handle everything for you.

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

How to get a STAC

You’ll need a STAC code to close down your number with us. Text ‘STAC’ and your date of birth (DDMMYY) to 75075 and we’ll send this to you. 
For example: STAC 071281

If you’d prefer, you can also get your STAC and view outstanding charges by logging into your My3 account, using the Three app, or by contacting us. 

Please note that you won’t be able to upgrade online for 30 days once you’ve requested this code. If you don’t use your STAC code within 30 days, your contract with us will carry on as normal.

How to cancel my contract 

If you want to leave Three and you aren’t moving to another provider, you don't need PAC or STAC code. Simply give us a call.

You'll need to give us 30 days' notice, and at the end of it we'll cancel your number and stop billing you. 
Remember though, if you do this, you'll lose your number forever and we won’t be able to get it back. If you want to keep it, you'll need to get a PAC code and take that to a new provider.


The following information is applicable from 3rd April 2023.

If your PAC or STAC information hasn’t arrived within one minute of submitting a request either via SMS, through our Three app or your My3 account or one minute from the end of your phone call where it was agreed this would be sent, you could be entitled to compensation.

To discuss your compensation rights or make a claim, please contact us.

Business customers may be entitled to compensation if a PAC or STAC code hasn’t arrived within 2 hours of asking for it via the phone, or within 2 working days from an online request.

For businesses with 24 mobile numbers or less, you may also be entitled to compensation if your PAC or STAC code hasn’t arrived within 2 working days from requesting it by SMS.

To discuss your compensation rights on a Business account, please contact us.

Yes, your account will remain active until you share your PAC or STAC with your service provider, your account will remain active. 

There are two key steps in both the PAC and STAC processes. You first request a PAC or STAC code and then you share this code with either, your future provider (PAC), or with your existing provider (STAC). 

If you requested a PAC or STAC on a Pay As You Go account, you’ll be given an up-to-date balance of any remaining credit you have at the time of the request. Once the transfer has completed, you can request a refund of any remaining credit that was still on the account when it was closed, and any entirely unused Add-ons and Data Packs, where the product hasn’t been used since purchasing.

To request a refund of this, please get in touch. We can arrange for this to be refunded to the card it was purchased from (where possible) or transferred to your bank account.

Note: refunds on remaining Pay As You Go credit balances are only available when leaving Three through the switching process (i.e. obtaining a PAC or STAC and giving this to your new provider).

You’ll receive your final bill within 38 days of you cancelling your account with us.  

We’ll send this final bill to your registered billing address. If you need to update your registered billing address either using your My3 account or contact us here.

To ensure everything runs smoothly, please do not cancel your direct debit with Three until you receive your final bill, and your final payments are settled.

If you’ve been abroad recently, you may receive an additional future bill. Some international roaming charges can take up to 3 months to register on your bill.

If your account is in credit when your account closes, you may be entitled to a refund.  

Any refund owed to you that’s over 50p in value will be sent directly to your registered bank account within 14 days of your receiving your final bill. 

If your refund is less than 50p, you can call 0333 338 1001 to arrange a refund, otherwise we will donate this credit to our charity partner. 

Please note, not all types of credit are eligible for a refund. To find out more about our terms and conditions on refunds, please visit

Please get in touch and we will support you with this change.

When you close your contract with Three, any associated insurance contract will also be closed.

If you’re a business customer and you’re thinking of leaving Three, you’ll find more information in our business help section. If you’re not the actual Three account owner, please speak to them first.

Alternatively, please get in touch and we can arrange this for you.  

If you’d like to move your current Three number to another Three account, please get in touch.   

Please note, due to system constraints, this can be a complicated process and may take some time to complete. We are looking to improve this process as soon as we can.  

If your account was closed less than 90 days ago, you can still request a PAC to switch your number from Three to another provider. To request a PAC on a closed account, contact us.
