Transport for London confirmed to the Guardian that 4G mobile phone technology would go live in tunnels on most of the Jubilee line from March 2020 and on other lines in the coming years. The move raises the prospect of commuters making and receiving phone calls while packed into typically largely chat-free tube carriages. Mobile phone coverage has been standard in many subway systems around the world for several years, with some cities such as Moscow offering commuters both wifi and mobile phone connections. Mobile phone networks will then pay the private operator for access to the network, with the transport authority receiving a cut of profits. Merseyrail is installing a wifi network in its Liverpool tunnels, and the Glasgow Subway is experimenting with 5G services.
