October 2017

Over the summer our results showed that the best overall performing 4G mobile network in Wales was provided by Vodafone while the company also delivered the best performing 3G network in England and Scotland for the same period.

Best Overall 4G Operators (Tutela ranking)

These findings follow the collation and analysis of over 92 million data records gathered between July 1 and September 30, 2017.  Performance criteria were based on a formula using a combination of throughput, latency, packet-loss and jitter values to determine an overall performance ranking.

The same results showed  that the best performing 4G network in England and Scotland over the summer was delivered by EE.

About our testing

Tutela tests mobile networks by crowdsourcing anonymous sensor data from hundreds of millions of Android and iOS mobile users across the world. This enables us to collect billions of measurements every day and gain a real-world understanding of the mobile experience that mobile users are getting - not just in major towns & cities, but in all parts of the world.

Our testing methodology is designed to simulate typical user mobile behaviour, such as downloading a photograph or web page, rather than measuring the maximum performance, such as the peak download speed during a very large file transfer (which very few users will achieve) so that we can understand a typical user's experience.
