Uswitch services are provided at no cost to you, but we may receive a commission from the companies we refer you to. If a deal is "promoted" on Uswitch's tables, then it has been lent additional visibility as a result of us securing exclusivity on a great deal, or a commercial agreement to showcase what we believe to be market-leading value to consumers.

Until 2024, many mobile networks have increased contract prices in line with inflation. Starting in January 2025, Ofcom will introduce a ban on inflation-linked price hikes for new contracts. Future price changes will need to be set and fully disclosed in pounds and pence.
There are no speed limits and no data caps with Three - just endless streaming, browsing, gaming and sharing in the UK.
All Three SIMs are set up to give customers access to their super-fast 5G network. This now covers 54% of the UK outdoor population with average speeds of 204Mbps.
A loyalty app for all customers that gives money off big brands - #1 coffees at Cafe Nero and £3 Cineworld tickets.
Three’s range of benefits include:
Three’s customer app is available for iPhone and Android. It allows Pay As You Go customers to buy extra add-ons, top-ups and data packs. Customers can also see their usage and change their plan.
Pay Monthly customers can buy add-ons, view all recent bills, track their usage, set spending caps and change their plan via the Three app.
Download the Three app for iPhone.
Download the Three app for Android.
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.
Three allows customers to use their monthly data allowance for tethering. So, customers can use their phone as a portable Wi-Fi hotspot to get online with other internet-enabled devices.
Three’s inTouch Wi-Fi calling service is on offer to all customers and allows them to call and text in the UK in locations where there’s no mobile signal.
Calls made using inTouch come out of customers’ pay monthly customers’ monthly calls allowance.
