Although Root Metrics have already established themselves and their work in the US. Hull is the only location which has been completely mapped across all the major UK carriers. The interactive map itself allows the user to select which network’s coverage they want to see overlaid and although it’s early days, the accuracy and coverage of the current UK map is only likely to get better with time.

The key advantage to checking coverage in your area with an independent map such as that of Root Metrics’ is that, according to The Register, unlike the UK networks who create their maps using a mixture of topology and cell tower placement without taking into account heavy usage and overload risk on a tower-by-tower basis, the American company also base their coverage data on actual speed tests for the various frequency bands and voice or data usage.
