Despite being a good 100m under the sea, the Channel Tunnel has now gained 4G coverage, which lets travellers access download speeds 10 times faster than 3G allows.
What this means is that those using the 'chunnel' will be able to download and share content and watch streamed videos on their phones, tablets and laptops, just as quickly as if they were using home broadband, Eurotunnel claims.
The arrival of superfast data speeds follows cooperation between Eurotunnel and phone networks EE, O2, Vodaphone and Bouyues Telecom, which should provide full 4G coverage for those making the 35-minute journey between Kent and France on both le Shuttle and high-speed passenger train services, reports the Press Association.
Following the announcement, chief operating officer for Eurotunnel Michel Boudoussier told the Press Association: "This new service means we can offer our customers incredible connectivity and astonishing access to mobile services, bringing better information for passengers, allowing them to remain operational and make their journey a real opportunity to relax."
Marking the arrival of 4G in the tunnel, a live performance by the French pop/rock band Archimede was broadcast from a train careering under the channel at nearly 90mph.
