Buy Three.

Three is one of the best networks for UK population coverage, but if you prefer to double-check you’ll be getting the best service with Three, you can use their coverage checker. This gives you easy-to-read colour-coded data to determine how good the coverage is where you are.

Three coverage is outstanding, covering 99.8% of the UK outdoor population. Their 5G network is growing every day and with aseveral5G zones around the country, getting online has never been quicker. You can look at Three’s postcode checker to find the 5G zones, then get yourself a 5G device to access it.

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.
