Ofcom Says UK Train Mobile Signal Meets Basic Streaming Standard Only 42% of the Time

Summary
EE, the best-performing network in Ofcom’s rail tests, met the regulator’s minimum “good performance” standard only 42% of the time; Vodafone managed 17%, Three 21% and O2 20%.
Ofcom set that bar at 5 Mbps download, 1.5 Mbps upload and 50 milliseconds latency—enough for video calls, social media and streaming—but said passengers still lose usable service most of the time.
24 rail sections across England, Scotland and Wales were tested, with weak mast coverage along tracks and train carriages blocking signals identified as the main causes.
Train wi-fi performed well just 1% of the time, which Ofcom linked to outdated onboard technology and heavy throttling by operators.
More than 9 in 10 mast applications were rejected in some local authorities over five years, as Mobile UK and Ofcom pressed for planning reform and wider investment; the government is also preparing a £57 million satellite-backed train wi-fi upgrade.
