Virgin Media - who are an MVNO on EE’s network. I only just got the SIM update a few days ago to say I’d been enabled to be 5G ready. I didn’t do anything to get that so guessing not all providers have switched on yet.
I did see engineers unpacking and fitting equipment at the local mast a couple of months or so ago, and the mast went down every day for a week or two for “maintenance”.
I assume there are products that go on the outside of your house to act as the antenna to improve reception?
I just went for a little driving recon (because I’m THAT exciting on a Sunday morning!), seems just about all of fair oak is covered, bits of bishopstoke, and even less of Eastleigh- most of Eastleigh didn’t get it at all.
If I was needing a broadband provider in fair oak now I’d strongly be considering 5g over Virgin Media / BT / alternatives. Clear benefit is you’d be able to pick up your router and take it on holiday with you!
