inquisitor, thank you for the fast reply!
Still, may I clarify a bit further? I will definitely go for A1, network coverage is important. I checked the web-link you provided. I understand that I need to look for B.FREE package, but it also talks about USB modem, etc - which is not my case. I will not have laptop with me, I can only use GPRS... So, when I am in the supermarket, or somewhere else, what is exactly the package I should look for? "B.FREE Breitband 1 GB" ? But I cannot find sim-card in the description... Or do I need "B.FREE Breitband Welcome Package" ? Maybe you can provide the link to some store, which shows exactly how the package looks like, so that I can look for exactly the same?
Sorry if my questions are stupid... Normally I can easily understand and find anything I need on web-sites in English, but German makes me feel helpless
And regarding eety I totally agree - it is increadibly cheap!
Thanks again for your help!
