The vast majority of the Northern, Bakerloo and Metropolitan lines are expected to have coverage in the tunnels by the end of summer this year.
All four major mobile network operators (Three UK, EE, Vodafone, and Virgin Media O2 (VMO2)) are taking part in the rollout, which is delivered to TfL at no cost under a concession agreement with Boldyn Networks.
The expanding coverage will also support the new Emergency Services Network (ESN), which, when fully operational, will give first responders immediate access to life-saving data, images, and information in real time during emergencies on the frontline.
In addition to delivering coverage on the Tube, TfL and Boldyn are working to introduce coverage to sections of the Docklands Light Railway (DLR) that are underground, as well as the Windrush line between Highbury & Islington and New Cross.
