yes Aldi Talk website and through their Aldi Talk app. works great.

i also have find another cheap alternative for data in europe..ekit global premium sim $0.39/mb (approximately €0.29) to many european countries ekit, Mobile Info

Do they actually charge you roaming costs when you call 11551 from abroad? (I only used the roaming package by activating it online until now...)

Another great sim for 1-day-usage in Europe is the Irish Vodafone which gives you 50MB for €2,99. Its advantage over Aldi Talk is that it works in some European countries which aren't part of the EU, like Switzerland, Croatia and Albania.

No, the 11551 is free of charge.

i think also vodafone-Italy has a similar offer.
