The cost of text messaging and mobile internet use abroad must be significantly lowered by 1 July 2008 or the European Union will introduce a mandatory price cap. The European Commission estimates that a text message sent from another EU Member State can cost up to 20 times more than one sent from a person’s home country, and downloading data abroad can cost at least four to six times higher than equivalent domestic rates. To remedy this, the Commission has suggested the "voluntary" introduction of EU-wide roaming packages, which would bring international rates closer to domestic rates. However, mobile phone companies have warned against introducing regulation on data roaming, claiming it could stifle innovation in the sector.
