Extra costs for using mobile phone data in Europe have come into force following Brexit, but one provider says many people aren't aware what they'll be charged if they use their phone on holiday this summer.

“Let's celebrate having something we already had!," one actor exclaimed after Boris Johnson and Nadine Dorries boasted about free roaming.

Most networks are reimposing the charges post-Brexit, after the EU abolished them.

Since the Brexit vote, some of the UK's biggest mobile phone operators have revealed that they will be reintroducing roaming charges in the EU.

All four of the main UK mobile carriers have now announced plans to reintroduce roaming charges for customers traveling within Europe, following Brexit.

EE has announced it will reintroduce roaming charges from January, despite saying just months ago it had no plans to do so after Brexit.

The announcement was made on the five year anniversary from Britain’s vote to leave the European Union.

EE will bring back roaming charges for new customers who use their phones in Europe.
