Three has confirmed that it will soon provide free Wi-Fi services to customers using the London Underground.

Speaking yesterday, the operator’s director of customer strategy, Danny Dixon, said that the new networks would be launching by the end of July. Customers will be able to enjoy access at 137 London Underground stations, with ticket halls, corridors and platforms, all covered free of charge.

The service comes courtesy of Virgin Media who originally installed the Wi-Fi network ahead of the London 2012 Olympics.

Three is the latest major UK operator to announce a Wi-Fi network on the Underground – O2 revealed last April that any of its customers who subscribed to its services would automatically be registered for free access without requiring a sign-up above ground or needing to remember a password, and EE and Vodafone also offer access across the Tube network.

"Our customers will also have the added benefit of being able to use our newThree InTouch app, which means they will be able to surf the web and also make and receive calls and texts whilst travelling underground," Dixon added in a statement to CBR.

There is no news on whether Three’s coverage will extend to the London Overground network, whose free Wi-Fi services are provided by BSkyB-owned TheCloud.
