Lots of people now have flat-rate data plans for their phones, but these plans usually aren't flat-rate when you're in a foreign country. Using data while abroad has traditionally been very expensive, but the EU is now trying to introduce caps on data roaming charges. Under the plan, data roaming charges would be capped from July 2009 at 1 euro per megabyte, falling to 50 cents per megabyte by July 2011. These are caps so phone networks could charge less of course, but they could not charge more.
