Quite simply, the best 4G network is the one where you can get a signal. Some providers claim 99% coverage of the UK; however, this 99% figure is for populated areas and not the entire UK. Whatever the claim is, it is pointless when a 4G signal doesn’t cover the area where you need it.
Some construction sites are in underpopulated areas, and coverage can be patchy at best. For this reason, we use the best network for the area to achieve reliable 4G broadband. If we are not happy with the performance of 4G in a particular area we can even install satellite based broadband, so we can supply and install broadband with 100% coverage of the UK.
