Compare Three phone deals

Three is one of the UK's four main licensed mobile networks, owned by CK Hutchison. It built its reputation on unlimited data and was one of the first UK networks to take data allowances seriously — making it a natural choice for heavy data users who want a phone contract rather than just a SIM.

On our feeds, Three stocks Samsung Galaxy and Google Pixel devices. The Samsung range covers Galaxy S-series flagships and selected mid-range models, while the Pixel range includes Google's current lineup. If you're looking for iPhone on Three, you'll need to go direct to Three's own website as those deals aren't captured in our current data.

Three includes Go Roam on all plans — letting you use your UK data, calls and texts in 71 countries at no extra cost. This is one of the most generous roaming inclusions of any UK network and makes Three particularly strong for frequent travellers. Unlimited data plans are available across the device range, which is unusual for network-bundled phone contracts where most providers cap data at 30–100GB.

Three's 5G rollout is concentrated in major cities, with strong coverage in urban areas. Rural coverage can be patchier than Vodafone or EE, so it's worth checking the Three coverage map for your area before committing.
