EE on top in mobile network reliability tests - but who was worst?

EE continues to fill its trophy cabinet with performance-related silverware, but which network received the wooden spoon in the latest tests by mobile analytics firm RootMetrics?

Hot on the heels of claiming top spot in Ofcom's mobile phone reliability tests last week, EE has once again received plaudits for the performance of its network.

EE, Three, O2 and Vodafone were put to the test by mobile analytics firm RootMetrics - whose data UK communications overseer Ofcom used for its own research - to determine the quality of calls, texts and mobile internet on each of the UK's major networks.

The research which took place during the first six months of 2014 was based on more than 920,000 tests.

Unfortunately, but maybe unsurprisingly, if you're on Vodafone, it was your network which came in last, although O2 was not far ahead.

However, there is a silver lining if you're on Vodafone - RootMetrics said that all four networks had shown signs of improvement over the last year.

If you're on Three you can feel pretty pleased with your choice of network, as it came a close second across the range of categories, scoring 84.3 out of a possible 100 points compared to EE's 88.1.

Tests looked at overall performance, call performance, mobile internet performance, text performance, network reliability and network speed, and, when it came to network reliability, there was less than one point between Three and EE.

"Today's results, along with last week's report from Ofcom, show that EE is providing the best mobile experience to businesses and consumers across the UK," said Olaf Swantee, EE's chief executive.

"We continue to invest in getting even better, and setting new standards for performance and reliability."

However, while network performance may be EE's yin, yesterday's news that it is introducing a chargeable customer service queue-jumping option, was the yang, and customers aren't impressed.

The biggest difference in the RootMetrics' results came in mobile internet performance, where EE's score of 85.5 put it a whopping 18.5 points ahead of Vodafone's mediocre 67, with O2 not doing much better, scoring 68.1. This significantly lowered Vodafone and O2's overall performance.

Vodafone said its spending £1billion on improving the quality of its network and mobile coverage this year.

A Vodafone spokeswoman 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."

The good news if you're on O2 and Vodafone is that when it comes to good ol' fashioned calls and texting, which is after all pretty critical for a mobile network, both networks performed well.

The ongoing roll-out of superfast 4G mobile internet by O2 and Vodafone is also expected to narrow the gap in performance following EE's head start, so things may start to look up in the coming months if you're on either network.
