Easiest way to cancel your mobile phone contract

Here's a step-by-step guide to getting out of your existing contract and moving to a cheaper deal.

Cancelling your phone contract is just a text away

If you want to cancel your UK phone contract, the good news is you don't have to phone your network provider and listen to their hard sell before leaving.

Instead, you can cancel phone contracts with a free text message.

This guide will take you through all things you should consider before ditching your current deal, but if you've already done your homework and want to leave now simply scroll down to the section titled 'Cancel phone contract by text.'

If you're unsure of what to do next, let's start by looking at why there's a good chance you are paying too much and when the best time to switch is.

Most of us on the wrong phone deal

The fact is, most of us are paying for more than we need in the first place.

Research from Citizens Advice in 2019 estimated the average person was paying for 2GB of data every month that they didn't use – and that's before unused texts and minutes were considered. 

While some mobile phone providers do allow you to roll over the data you don't use at the end of each month (for a limited time), such as Sky and EE, most of us are simply wasting money on the wrong deal (you can search for cheaper ones here).

Are you actually using too much data? Here's how to cut your usage and avoid hefty charges

If you're out of contract soon – and remember networks are required to inform you when you're nearing the end of one – then it's vital you move to the right deal for you.

Given this will often involve changing networks (because most networks still offer better deals to new customers), the rest of this guide will take you through the steps for switching mobile phone providers as painlessly as possible.

Can you cancel without paying?

The first thing to do is to confirm you're definitely able to switch penalty-free. 

Here are the contact numbers for some of the major providers (although as we'll explain in the section 'Cancel phone contract by text' you can also get this info with a single message).

  • Three: 0333 338 1001
  • O2: 0344 809 0202
  • EE: 0800 079 8586
  • Vodafone: 0333 304 0191

Pay-monthly contracts typically last between 12 and 24 months, while SIM-only deals usually last 30 days or 12 months. If you are on pay-as-you-go (PAYG) you won’t be locked into a contract.

Also, take a look at your current Pay TV supplier: Sky, for example, has mobile phone deals reserved for existing TV customers.

How to switch or cancel mobile phone deals

Check if your handset is locked

If you have a mobile phone that you took out as part of a contract, check if you can take it with you when you move.

You are entitled to keep a handset after your minimum term ends or when you pay to cancel the contract, though there could be a minimum term stipulation.

You should check if the handset is ‘locked’ to your network although the regulator, Ofcom, has banned mobile phone companies from selling locked phones from December 2021.

If your handset is locked, your phone provider may be able to unlock it so you can use it with any network, but some may charge a fee or only do it after a certain period.

Unlocking a phone can take 10-28 days, so make sure you factor this in when switching to avoid losing service.

Find a cheaper deal before cancelling

Once you’ve figured out where you stand on your current deal, it’s time to think about the network and tariff you want to move to next.

If you’re struggling with service make sure you research which provider can offer you better coverage and take a look at which companies attract the most and least complaints in our guide to the UK's best and worst mobile phone providers.

To make sure you pick the right plan for you, work out how many texts and minutes you will likely need. You might want to look at old bills to see what your usage is like.

If you don't have any to hand, some smartphones will also allow you to check your monthly minutes, texts and estimated data usage.

Next, you should work out what sort of deal could work for you: PAYG, pay monthly or SIM-only. Here’s a quick refresher on what they offer and who they are good for:


With a PAYG deal, you don’t get a phone, inclusive calls/texts/data and there’s no credit check, contract or monthly bills. You just top up your account manually and pay for calls/texts/data at your network’s rates.

This type of deal is good if you have a phone that you don’t use that often or only really need for emergencies, or if your credit history isn’t great and you don’t want to commit to a long contract.

Pay-monthly contracts

With a pay-monthly contract, you usually get a handset and an allowance of inclusive calls, texts and data for a monthly fee. Contracts can last between 12-24 months and require that you undergo a credit check before taking one out.

This type of deal is best if you are likely to make a lot of calls, send many texts or use a lot of data on the go. It’s also good if you want the latest top of the range handset but can’t afford to pay for it outright.


A SIM-only deal can offer a happy medium between a contract and PAYG.

They don’t come with a handset, but you get inclusive calls, texts and data for a monthly fee.

A SIM-only deal makes sense if you make a lot of calls or text and use data, might not have the best credit history (30-day rolling contracts don’t normally require a credit check), don’t want to be locked into a long contract and have a handset you can use.

You can compare PAYG, pay-monthly and SIM-only tariffs using most price comparison sites or a dedicated service like Carphone Warehouse. It's generally a good ideally to compare prices on at least a couple of sites to get a better idea of how much you should be paying.

Once you’ve found a new network and deal that suits you and are ready to move, you can initiate a switch.

Cancel phone contract by text

Up until a few years ago, if you wanted to cancel a contract, you'd have to phone your provider to explain that you wanted to leave, which was usually followed by a hard sell.

In July 2019, a new ‘text to switch’ automated system was introduced, making it much easier to move to a new mobile provider.

Under the system, you just need to send a free text message to your provider stating you wish to leave.

The provider will then send a text back with a unique code and any other related information to closing your account like termination charges and outstanding handset costs.

If you’re happy with these costs, you then pass on the unique code to the new network, which will switch you over within one working day.

See the diagram below from Ofcom for more information on how it works.

To be clear, you can still cancel over the phone if you wish – the text to switch service is merely an alternative way to cancel.

How to cancel your mobile phone contract by text

Whether you're looking to cancel with Virgin, Tesco, Three or anyone else, the number you'll need to text is the same (although it does vary based on whether you want to keep your number, as we'll explain in a bit). 

The annoying thing is each provider has a slightly different process: for example, Vodafone asks you to text the word 'PAC' plus your PIN to cancel, while Virgin wants 'PAC' plus your date of birth.

It can be confusing so it's often best to simply text the word 'PAC', which will kick start the process (although it might require you to provide some extra info).

So, what number do you text to cancel your mobile phone contract? That depends on what you want to do with your existing number.

Text the number that best describes what you want from the three scenarios below.

I want to cancel and keep my number

For this, you'll need to text 'PAC' to 65075 to begin the process.

I want to cancel and get a new number

If you're keen on changing your mobile phone number, you should text 'STAC' to 75075 to kick things off.

I want more info before I cancel

If you're unsure of your current contract situation and want to know about any fees you might face, text INFO to 85075 and make a decision from there.

Keeping your number or choosing a new one

When switching to a new provider, the process varies slightly depending on whether you want to keep your existing number or whether you're happy to be given another by your new provider.

We'll talk you through the steps for each below, looking at how it works if you want to sort it over the phone or by text.

Keeping your existing number

By phone

To keep your existing mobile number when switching networks, you can phone and ask your current provider for your Porting Authorisation Code or PAC.

Your existing provider should give this immediately to you over the phone or within two hours by text.

Your PAC is normally made up of nine digits and is valid for 30 days. If not used within this time it will expire and you will need to request a new one.

Once you have provided your PAC to your new provider, they will contact your old provider to port your number. This should take one working day.

By text

Simply text 'PAC' to 65075 and your existing provider will respond by text within a minute.

You'll be sent your PAC, which will be valid for 30 days. Your provider’s reply must also include important information about any early termination charges or pay-as-you-go credit balances.

You then give the code to your new provider, which must arrange for the switch to complete within one working day.

If you don't want to keep your number

By phone

If you are happy to be given a different number, you just need to contact your new provider to apply for a new service and contact your current provider to end your existing contract.

By text

Sent the word 'STAC' to 75075, and you'll receive a service termination authorisation code, which you can use to ditch your provider.

The text that you'll receive in response must include any important information about early termination charges or pay-as-you-go credit balances.

How long will it take and will I lose service?

It’s a good idea to time the end date of your old contract with the start date of your new one to prevent overlap.

You shouldn’t lose service while your number is switching networks. Your number will stay active on your old SIM up until it becomes active on your new SIM.

When the number switch is completed, you just need to swap your old SIM for your new one with your new network.

Check the SIM you have works in your new phone and that the number has been transferred across.

Your rights if you’re not happy

You have 14 calendar days from the date you enter a new contract with a new provider to cancel your request to switch without being charged.
