Actually, maxroam, according to their FAQ, were supposed to be charging 1 euro/month whether the card is used or not. But, they have not been implementing that charge. I have the card and have never been charged.

Maxroam, like yackie, also allows you to add several numbers to your sim card, however they do not stipulate that you have to hold the number for 3 months (Just 1 month), and I do not think there is no setup fee for the number.
