Rejoice/commiserate: from Friday people will be able to make phone calls while on the Underground.
Network provider EE is launching a service which will mean phone signals will switch over to wifi without interruption allowing people to continue talking even when at Hampstead station (the deepest station below street level).
Initially it will only be available to people with Lumia 640 phones and the new Samsung Galaxy S6 and S6 Edge, but it's expected to be rolled out to iPhone users by summer.
With wifi only available on the platforms of the 150 stations equipped with the service, expect an explosion of "I'm just going into a tunnel" to erupt on carriages. We're wondering if it'll engender a new addition to the Londoner's vocabulary.
