Getting cheap rates for mobile phone data in Europe is often tricky, so any drop in costs is welcome. Roaming provider TravelSIM has reduced its data rates in 33 European countries from $US3.60/MB to $US1/MB, making it a little cheaper to post those crucial Facebook updates.
Like many a mobile data service, the rate is charged in 10KB increments. That's still not a particularly cheap way to get data access (and you'll want to latch onto free Wi-Fi whenever you can), but it beats what your provider is likely to charge. For reference, here are the countries which the deal covers:
Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Monaco, Netherlands, Norway, Poland, Portugal, Romania, San Marino, Slovakia, Slovenia, Spain, Sweden, Turkey, United Kingdom, Vatican City
No Lichtenstein, but I guess you can't have everything.
