5G in my area renders phone connectivity useless

[jaykayhk]

I have an iPhone and also an Android phone, both 5G compatible. In London 5G works superbly. In Milton Keynes, where I live, 5G connectivity means no online connectivity whatsoever. This means online parking payments, dropping parcels off, etc is next to impossible. Why is the 5G so bad? I'm now employing an old 4G Samsung Android phone with a Giff-gaff card just to be able to function

Hmm,  no replies. Guess will just have to try and call someone at Sky and find out why there is such an issue.
