The roaming data charges while traveling through Europe are set to fall significantly after new regulations were passed by the European Parliament today.
The rules include a cap on the amount operators can charge for roaming services and will allow consumers to use a different operator abroad from the one they use at home.
The European Parliament passed the new price caps by a huge majority.
Data charges will be capped at 70c per megabyte from July, falling in stages to 45c in 2013 and 20c in 2014.
At present there is no limit on what operators can charge for data roaming.
Making a call will cost no more than 29c per minute from July, down from the current maximum of 35c.
This will fall further to 19c in 2014.
Text messages will fall from 11c to 9c in July, and to 6c in 2014.
The new deal also means that from 2014, for the first time, phone users will be able to buy roaming services abroad from a different operator than they use at home, without any charge for switching and keeping the same number.
The new rules will be adopted by the Council of Ministers next month, and take effect on 1 July.
