The 'euro-tariffs' will see costs capped at:
Outgoing calls will cost no more than 15p per minute
Incoming calls will cost no more than 4p per minute
Text messages will cost no more than 5p per message
Online browsing will cost no more than 16p per megabyte
The cost of using the internet in an EU country has fallen by over 50% with the previous cap set at 36p per megabyte.
The drop in prices will come as good news to the 25% of Britons who have been hit by a larger than normal bill after visiting a European country, uSwitch figures suggest.
Is there anything else I should know about the drop in EU roaming charges?
Neither Switzerland or Turkey are covered by the 'euro-tariff' caps and it is likely that you will be charged more for using a mobile phone in those countries.
Some 41% of Britons wrongly think Switzerland is in the EU while 38% believe Turkey is, according to uSwitch.
