Each network has its own network coverage checker and they give a good indication of the actual coverage you can expect. Ofcom has recently checked these online tools and finds them broadly accurate. However, do bear in mind that local geographic features, your handset, the number of network subscribers in your area, the distance from your local mobile mast, time of day and, if you’re inside, the building materials of your office or home will all have an impact on your reception – so these maps can only ever be indicative, rather than 100% accurate.
