Mobile broadband provided by O2 loads webpages quicker than any other UK network, research by Ofcom has found.
The regulator carried out 4.2 million speed tests across the country.
It found the average download speed across all networks was 1.5 megabits per second (Mbps), rising to 2.1Mbps in better coverage areas.
Claudio Pollack is Group Director at Ofcom and he ran through the results with the BBC's Simon Jack.
