Best 5G networks in September 2020

5G networks

Whichever network you choose, a 5G plan promises quicker downloads, smoother streaming and better online gaming. But not all networks are created equal when it comes to 5G coverage and speeds, which means you’ve got a big decision to make.

Which 5G network is best for coverage?

As of May 2020, EE’s 5G service is available in 80 towns and cities across the UK. That means it’s the widest-ranging of any UK network.

As you’d expect, you can get EE 5G in major cities such as London, Birmingham, Glasgow and Manchester. It's also in more than 50 towns, ranging from Ashton-under-Lyme to Weybridge.

Which 5G network is fastest?

A 2019 study from Oooka found that EE was the UK’s fastest 5G network, with an average speed of 205.02Mbps.

That’s well ahead of O2 and Vodafone, which came in at 159.48Mbps and 140.15Mbps respectively.

When the report was carried out, Three had yet to launch its 5G service. This went live in February 2020, with Three trumpeting plans for the UK’s fastest 5G, bar none. Whether that’s true remains to be seen.

Which 5G network is cheapest?

That largely depends on the plan and the allowance you choose. However, in general we’ve often found that some the most attractively priced, cost-effective 5G plans are on Three and O2.

Both of whom are offering 5G for the same price as 4G.

Is 5G more expensive than 4G?

In the majority of cases, you will pay more for a 5G contract than a 4G one. But given that 5G is a much faster service, that’s probably to be expected.

However, that’s not always the case. Three 5G plans, for instance, are priced in line with its 4G contracts. So it’ll cost you nothing extra to upgrade to a faster service (provided you already own at 5G-enabled phone, that is).

O2 is also offering 5G plans at the same prices as its 4G contracts. And with the same allowances and benefits too.
