Three’s 4G is hugely popular – and for good reason, since it covers 99.8% of the UK. The key difference between Three’s 4G and 5G is speed. 5G offers you what you need, at super-fast speeds of up to 140MHz – that’s 50MHz more than any other UK network operator!
All deals on the Three network come with 5G at no extra cost, so you don’t have to worry about deciding between the two. As long as your mobile supports 5G, you can enjoy super-fast data speeds wherever there's coverage.
To take advantage of 5G data speeds, you have to have a device with the relevant 5G technology, so a 4G mobile won't be able to use 5G.
You can easily manage your Three account using the Three app, known as My3. It's a quick and easy way to check your allowances and bills, and access information about Three’s offers and discounts.
