Big areas come and go form the predicted coverage map all the time around these parts, some have been predicted on the 2g map, the 3g map and the 4g map at different times, but nothing seems to actually ben happening sadly, in fact I don't think a single mast has been upgraded outside of a large town or motorway link in over 6 or 8 months
also when you look in many large towns at some of the roof top mast infrastructure its clear many have not been touched as its easy to spot the old V/O2 panels, There dragging there feet for some reason in quite a few areas I've been,not just where I live and work too. at this rate they will be nowhere near by the end of 2017 unless the use some very creative software on the coverage maps..
