what is the general opinion on the best mob network for the Westbury area? I have had Virgin which wasn't that good, so, I changed to Orange and I still have some trouble. Wonder if it could be that I live in an old property with thick walls!!
Best two networks for call coverage are Orange and Vodafone by far.
Vodafone still uses the old 900 Mhz bandwidth it started its 2G service on in the early 90s. Orange and other newer networks work at 2 GigaHz +. The old lower frequency signals travel further and better between far apart masts in rural area making Vodafone a better bet across the UK overall. But in this neck of the woods, Orange has built a solid network that works better than Vodafone despite everything being at 2 GigaHz +.
O2 tends to have base stations in the centre of towns that cover town centres well but which can leave gaps between towns in rural areas.
T-mobile (and Virgin) is the weakest, though it has been catching up well. It still has only a 2G service.
