Proposals to slash the cost of using mobile phones abroad, for text, data and voice calls, could become law next July following a vote in Brussels. The European Parliament is to vote on whether roaming costs for text messages should be capped. The cost of sending a message is expected to eventually fall by 60% from an average of 23 pence to 9 pence. Voice calls would fall from 36 to 27 pence a minute and customers would be able to set limits on data downloads. A reluctant mobile phone industry first had limits on its roaming charges imposed by the EU in September 2007.
