5G is here on Three, bringing you incredible data speeds, a smoother experience when gaming and video calling, and a more reliable data connection in busy places like the football and festivals. Three has launched 5G in a load of busy towns and cities up and down the UK. See our Help Centre for the full list. Note: When you leave a 5G location, your 5G mobile will automatically switch to 4G or 3G, then back to 5G when it's available.
With access to WiFi on the London Underground, you can continue using your phone on the commute, checking Facebook and replying to emails, rather than getting cut off as soon as head down the escalators.
As a Three customer, you can download the Three+ customer loyalty app and enjoy exclusive offers on huge brands like Uber Eats, Cineworld and many more. Plus, music lovers can bag themselves pre-sale tickets to the UK's biggest festivals.
