The cost of making and receiving mobile phone calls while travelling in Europe has come down again.
From today, operators cannot charge more than 32p per minute (plus VAT) for outgoing calls, and 10p per minute (plus VAT) for incoming calls.
The new tariffs are the latest in a series of annual price reductions forced on the mobile industry by the European Commission.
Brussels has said it aims to equalise roaming and domestic charges by 2015.
Price regulation was introduced in 2007 by the then commissioner for information society and media, Viviane Reding.
Since then, the maximum call charge has been reduced by approximately 6% per year.
A group of UK mobile operators - O2, Vodafone, Orange and T-Mobile - attempted to challenge the Commission's price-cutting agenda, taking their case to the European Court of Justice.
However, their complaint was dismissed in June 2010.
