Today marks the day mobile roaming charges across the EU will be abolished.
Charges will be scrapped from this morning meaning it will be illegal for phone companies to charge people more to use their phones in one EU country than another.
This news means you can use data, calls and texts exactly the same way as you can at home, perfect for smartphone users.
Exceeding agreed minutes, texts and data will still be charged in the EU as it would in the UK, with all providers charging different rates.
The Roam Like Home legislation aims to prevent consumers receiving huge bills after downloading films or other data while travelling in Europe.
What are roaming charges?
These are extra charges for making calls, sending texts and using data when in a foreign country and apply as soon as a mobile phone uses an overseas network.
Under the new EU regulations, customers must be charged the same as if they were at home but this applies only to when they are travelling, and not to calls made from the UK to the EU.
Does the ban apply to the whole of the EU, and only the EU?
Travellers need to be careful about using their phones in some non-EU countries such as Switzerland and Andorra, as well as the Channel Islands and the Isle of Man, which are not formally part of the EU or even the European Economic Area (EEA).
Consumers should also be careful to check whether or not their mobile provider is including tourist hotspot Turkey in the ban.
Just to complicate matters further, country inclusion can vary further within the same provider depending on whether the tariff is pay as you go or pay monthly.
