A new piece of European legislation about 'roaming' charges has come into effect today, 1st March 2010. It was part of the same announcement that capped the cost of sending text messages within Europe last summer. This new law is designed to protect consumers from "bill shocks" by allowing them to choose a cut-off point once their mobile bill reaches a certain amount.
From 1st March, customers can ask their mobile network to set a 50 Euro maximum limit for data charges incurred within the EU – and from 1st July this 50 Euro limit will need to be put in place automatically for all customers who haven’t agreed any different amount.
