We’ve been looking into sim cards for Europe, and mainly something that has data and roams throughout Europe.
We found Europasim to be the best for us:
Its one of the very few that focuses on data. We definitely don’t plan on calling anyone, save an emergency. And text messages are pretty much irrelevant if you have data and can email/facebook etc.
For our 5 week holiday, internet use of up to 100mb/day will end up costing us about 100â‚¬ ($125AUD)… which in the scheme of the whole holiday isn’t much at all. We’re mostly interested in google maps and other research stuff while on the go. We’ll probably put the europasim card into our tablet, but may also use a smartphone when out and about (eg. maps).
