EE reckon they rolled it out in Birmingham and Manchester last May.
Where is 5G?
We're leading the UK on 5G rollout. We launched with 5G coverage in London, Edinburgh, Belfast, Cardiff, Birmingham and Manchester in May 2019, and have expanded 5G on a daily basis. We've since added 5G to towns and cities including Hull, Leeds, Newcastle, Nottingham, Sheffield and Sunderland, Northampton, Stevenage and Wakefield.
As well as switching on the first 5G sites in cities and large towns, we've brought 5G to more high footfall places, including London Euston Station, Cardiff Central station, Glasgow’s Bath Street and St Enoch Square, Belfast’s Kingspan Stadium, and Coventry’s Council House and Cathedral ruins.
