When is 5G coming to my area?

The 5G era is well under way, most major 5G networks up and running throughout the UK, so let's see how they all stack up.

EE

EE's 5G network launched in the UK on 30 May 2019 in six just cities - Belfast, London, Cardiff, Edinburgh, Manchester and Birmingham. It’s now available in 188 UK locations including major cities like Bristol, Coventry, Glasgow, Hull, Leeds, Leicester, Liverpool, Newcastle, Nottingham and Sheffield.

Vodafone

Vodafone's 5G launched on 3 July 2019, with its service available at first in Birmingham, Bristol, Cardiff, Glasgow, Manchester, Liverpool and London. It’s now available in around 138UK locations including places like Birkenhead, Blackpool, Bournemouth, Guildford, Newbury, Portsmouth, Plymouth, Reading, Southampton, Stoke-on-Trent, Warrington and Wolverhampton. It's also available in 240 different EU roaming locations.

Vodafone has made a big statement with its 5G offering by shaking up the traditional 'data allowance' system and instead offering unlimited data in a tiered speed system, similar to what you might get your broadband 

Vodafone has also now launched 5G and unlimited data for all its PAYG customers too. This enables people to benefit from the blistering speeds of 5G without the confines of a monthly contract.

Three

After a bit of a delay, Three's 5G was launched in February 2020, with the rollout initially covering 66 UK locations including London, Leeds, Glasgow, Bristol, Manchester, Liverpool, Aberdeen and many more.  It’s now extended to 303 locations at the time of writing so that’s great coverage. 

Three has dubbed its 5G as the ‘real 5G’ because it has up to twice the 5G spectrum of other networks. In theory, that means downloading movies and music and gaming online will be far faster on Three than on its competitors.

Three’s 5G also comes at no extra cost, all of Three’s SIMs are 5G ready as standard so all you’ll need is a 5G smartphone and you’re be good to go.

The company has also launched a 5G home broadband service in London. EE and Vodafone are offering home routers utilising 5G, as the need for traditional landline connections looks set to dissipate in the next few years.
