Re: > "selling point of 4G was greater range/capacity" - not around here
I live in a Southend-on-Sea suburb; O2's 4G here (Tesco Mobile) does not provide any data service whatsoever, not in the house, not in the gardens nor in the local high street or train station. Nada, nix, efokoli (Fanagalo for nothing).
There is a good signal, calls and texts are fine but data just wont work (no internet connection) and O2 said everything is working fine! 3G on the other hand works for the data apps, but only at 7-8Mb/s.
Around Southend there seems to be several O2 4G no-data areas. Really useful when you need mobile banking in a shop or business or want to Skype/FaceTime people.
If they can't make 4G work properly then I hold no hope that a 5G upgrade would be of any use. Maybe including Huawei kit would make the 4G work.
