EE tops mobile network performance awards in the second half of 2017 - RootMetrics
Three and Vodafone beat EE in the first half of 2017 for the reliability of calls. In the second half of 2017, EE shares voice category bragging rights with Three nationwide and in England and Scotland, while Three is a clear leader for call reliability in Wales.
Three has seen major improvements in data throughput as it continues to expand its LTE coverage. For example, it almost doubled its median upload throughput in London (to 11Mbps). Meanwhile, O2 ends up last out of four in most data examples.
RootMetrics gathers data from over 700,000 tests from outdoor, rail, and 649 indoor locations. Galaxy S8 (and S7) phones were used for testing.
- Plusnet Mobile, Virgin Mobile, BT Mobile, and ASDA Mobile use the EE network.
- Giffgaff, Tesco Mobile, Sky Mobile, and Lycamobile use the O2 network.
- TalkTalk Mobile and Lebara Mobile use the Vodafone network.
- iD Mobile uses the Three network.
SIM cards provided by MVNOs that are using Three's network will only work with 3G/4G devices, as Three does not operate 2G infrastructure in the UK.
