Vodafone: officially rubbish
It was found that EE have the best network for reliability, speed, internet usage, calls and text and Three and O2 are doing pretty well also.
All the networks were assessed on their coverage across the whole of the UK as well as closer looks at the way they performed in each of the four nations and 16 cities.
EE - the T-Mobile and Orange tag team - bettered last year's results by coming out on top in most of the 16 cities. Vodafone came last for mobile internet performance in England, Northern Ireland and Scotland, while 02 was the worst in Wales.
This is good news for Three who came last in 2013, but now lies second in the performance charts.
"While EE continues to dominate with strong performance at all levels across the UK-especially when it comes to speed-the other networks are on the march," said the RootMetrics report. "Three is starting to make a showing across the board, and Vodafone and O2 are building momentum."
"The good news: Better network performance across the UK means a better experience across all the points of your mobile life."
A spokesperson for Vodafone said: 'Regular independent testing of our network shows that our customers are experiencing a significantly improving network every day due to our massive ongoing investment. We are spending £1 billion on our network and services this year alone to improve mobile coverage and network quality across the UK. We are modernising the network with the very latest technology, building thousands of new outdoor sites and deploying hundreds of indoor coverage solutions."
'This investment has already delivered an improved service for customers across the country and we expect their experience to get significantly better as the momentum of our Project Spring investment, combined with our better quality spectrum, accelerates over the next year."
