Does the West Country have poor 4G Connectivity?

Generally when we tour the country we find that we can use our 4G data to use the internet. Obviously speed varies  but I don't recall having issues this year in the North East, Sothern Scotland (Solway) North West, Midlands. However since we have been south of Bristol in Somerset and Devon we have really struggled using the EE and O2 networks. We have not exactly been in the middle of nowhere either. Be interested to hear from those that live here. Hopefully this post actually gets through. It does speed up a bit in the late evening.
