BBC reports that the EU cap for downloading data doesn’t come into effect until the 1st July.

The consumers’ association Which? is warning that people going abroad with smartphones can still face huge bills if they connect to the internet.

By 1 July, new rules will come into force in the European Union which will cap bills for downloading data.

But, until then, people travelling in Europe could face unlimited bills.

So beware the big mobile data bill if you travel to one of the foreign conferences…
