Brit regulator finds mobile network service on trains is far from first class

Ofcom found that UK mobile networks on trains fail to meet performance standards, with 83% of rail segments showing poor signal and on-board Wi-Fi functioning just 1% of the time. EE had the best performance but still met 'Good Performance' thresholds less than half the time, while Three, O2, and Vodafone achieved it in 17-21% of journeys. Weak signal strength and high latency were primary issues, exacerbated by rural locations and carriage design.
