Everything you need to know about Three

Three was first launched back in 2003, at which point it was heralded as the first 3G only UK network.

Fast forward to the present and Three now has around 9.5 million customers using its mobile phone services. Three’s network spans 99% of the country, which is a big reason to its success among UK consumers.


Three offers extensive 3G and 4G coverage across the UK, with 99% of the UK outdoor population covered. Three’s award-winning 5G network now covers 54% of the UK outdoor population, across 400 towns and cities. The network is rolling out 5G to more areas each day.


Three’s 4G network has an average connection speed of 25.2Mbps, according to OpenSignal in April 2021.

Three's average 5G speeds were measured at 204Mbps in April 2022, according to OpenSignal's 5G download speed report.


Three doesn’t offer a mid-contract early upgrade scheme that’s comparable to O2 Refresh or Tesco Mobile’s Anytime Upgrade.

However, customers on Three Pay Monthly plans are offered an upgrade within 30 days remaining on their contract.


You have 30 days to change your mind when you sign up for a Three deal. Within that period, if you decide you’re not keen to stick around, you can cancel for no charge by getting in touch with Three’s customer service.

If you choose to leave after the 30 day period and before the end of your contract, you may have to pay an early cancellation fee that will be equivalent to how much you had left to pay on your contract.

Customer Service

Three’s customer support team is available Monday-Friday, and 9am-6pm at weekends.

Three customers on Pay Monthly plans can get in touch with the company’s customer service team by calling 333, free from their mobile phone. Alternatively, customers can call 0333 338 1001 from any other phone and will be charged at their standard rate.

Three also offers the option to get in touch via live chat on its site.

The site is also home to a range of customer guides. Sample topics include: setting up your mobile phone, turning off data roaming, and the correct procedures to follow if your mobile phone is lost or stolen.


Three’s Essential and Advanced phone-and-SIM and SIM only deals are competitively priced. The latter are available as one-month, rolling contracts that offer flexibility, or as 12-month contracts.

Essential plans are cheaper than Advanced plans and typically start at less than £10 per month. That'll typically get you an allowance of 500MB of data per month and limited call minutes and texts.

The cheapest Advanced plans start at around £13 per month, with data allowances usually pegged at around 3GB-4GB per month. Expect unlimited calls and texts.

The chief difference between Essentials and Advanced plans is the range of benefits they offer. The best Three benefits, such as zero-data streaming with Go Binge and a wide-ranging inclusive roaming scheme, are reserved for Advanced plans.

Moving to Three and want to keep your phone number from another network?

Keeping your old phone number when you move to Three is easy. All you need is your PAC code, which you can get by sending a text to 65075 thanks to the text-to-switch initiative. Give your code to Three when you’re joining and they’ll be able to port over your number.
