SIM in Austria and Germany

[alexyag]

Hello .

I will be travelling in Austria and Germany soon for about 3 weeks.

Anyone can suggest me please what is the best option to buy a prepaid SIM card to be used in both countries with Voice calls and SMS ,
and about 2 GB of internet traffic .
I prefer to have all those in 1 SIM card and not buy 2 separate cards-
1 for Voice and other for Internet .

Also - can I get card that I'll use in both countries - Austria and Germany or it's much cheaper to buy one in Austria and then one in Germany ?

The most calls I'm gonna make from the phone are to Israel and Germany .

Thanks .
