Mobile coverage availability.
The data displayed on mobile coverage availability uses source data made available by Ofcom, which is based
on data from the mobile operators about how strong they think signal levels are at every location in the UK.
Each mobile operator has a slightly different approach to displaying coverage on its own map, including
assumptions on the handsets used, levels of call reliability and the expected signal loss when indoors or in
a car. Because Ofcom brings all mobile operator data together in a single place and holds it to a single,
independent standard, the mobile coverage availability information above may display different levels of
coverage than those seen on the operators' websites. We would therefore recommend you also check the mobile
provider's own coverage checker. Mobile coverage data is created by coverage modelling, and since this is
based on computer predictions is not error free. Ofcom update the source data quarterly and the mobile
network operators update theirs, but there may be times when the maps are based on slightly different data
and therefore show different coverage.
See Ofcom's own Mobile Coverage Checker for the full national map.
