Sorry about that!
I'm in Sheffield S25. According to Google Earth I'm 506 metres from the cell tower.
They recently did work on the local tower here in S14, website still claims no 5G.
I guess I can pull 40Mbit from it on 4G (though right after I got the e-mail saying the work was done I was only getting 7Mbit), but its a little sad when I can pull 90Mbit off O2.
I've ordered a Voxi SIM as I believe that will be the same mast as O2 as its O2/Vodafone so should be interesting. Getting a 24 month contract on Three was a huge mistake, but as is always the case it was performing better on my PAYG SIM before I got the contract than it was almost immediately afterwards I got the contract.
