Vodafone has come out top in independent mobile network testing company P3’s annual survey of call quality, outdoing its major rivals when it comes to voice connections.
P3 tested call quality, setup and success ratio on each network while driving and walking, both in major cities and smaller towns. It also tested call quality on the UK’s roads. It found that Vodafone’s calls connected marginally quicker than nearest rival O2, while EE and Three fell behind the pack.
Vodafone said the results were down to huge infrastructure investment. The network has spent £2 billion on its network and services since 2014. Over 5,000 4G sites were either upgraded or newly installed in that time, with its 4G outdoor coverage now reaching 95% of the UK population.
The company says it plans to spend a further £2 billion over the next three years, as it looks to ward off competition from BT–owned EE while undercutting the threat of Three.
Vodafone also came out top overall in London, with P3 saying its calls and data provided the best all–round service in the capital.
However, it was unable to topple EE from top spot in P3’s national data tests, instead being relegated to second place.
Vodafone UK Chief Executive Nick Jeffery said: "We're building the UK's strongest network designed, site by site, to meet all of our customers' needs, wherever they are. These results are a welcome validation that our massive investment programme is making a real difference for our customers."
