Why Three for Unlimited Data?
Three was the UK's first network to launch unlimited data and still offers some of the most competitive unlimited plans on the market. 5G is included as standard on unlimited contracts — no separate upgrade or extra charge.
For heavy users — people who stream video, game on mobile, or work remotely from their phone — Three unlimited plans frequently come out cheaper per GB than any other major network when 5G is included.
Go Roam also applies to unlimited plans, meaning you can use your unlimited UK data in 160+ destinations worldwide. Most other networks cap international data even on unlimited domestic plans.
Three+ Rewards: What Is Included
- Cineworld cinema discounts, 2 for 1 on selected tickets
- Caffe Nero free drinks and food offers
- Uber Eats cashback and discount codes
- Regular prize draws, holidays, tech and experiences
- Partner discounts refreshed monthly via the Three app

Looking for the right Three deal?
