It’s appalling that in such a small island we have such poor network coverage on all networks. EE has the best network coverage in wales along with Vodafone apparently yet all carriers will lie to you just to get you to sign up.
It is shocking indeed.
Back in 2011 I was travelling to work in the arctic circle, en route I stopped off at a small village in North Norway called Hasvik, it was an incredibly remote part of Norway yet the phone signal was excellent - full bars of 3G. Other parts of Norway had 4G then too.
Back home in Scotland at that time I was luck if I could get 3G on Vodafone in the town of 25,000 that I stayed in. In the sticks I had no chance.
I’m now on EE and they are by far the best for coverage and speed in general although there is still room for improvement west of Scotland.
