If youre an EE customer, and reading this on the 12:15 from Euston International, then you can continue to do so — over 4G — once you emerge from the tunnel without it costing you un bras or une jambe. Thats because the UK network has just announced its offering 4G roaming in France and Spain. EE states that youll be able to get 100MB of 4G roaming data for £3, which is probably less than the price of a Eurostar coffee.
