Lower mobile phone roaming charges in Europe come into force today.
The measures include an 11 cent price cap for sending text messages in the EU.
This is compared with a previous average price of 29 cent.
Making a phone call in Britain and Europe will cost no more than 43 cent per minute.
The most receiving a call will cost is 19 cent per minute.
Communications Minister Eamon Ryan has welcomed the move, which he said has been supported by Ireland since its inception.
