There is no easy answer to it. It depends if you need 4G/LTE or only 3G and how much data. Lidl's Surfkarte is a good offer on 3G only (€15/5GB). AldiTalk has similar prices mostly on 4G. Both of them require online registration. These offers are for Germany only.

There are many SIM cards with roaming in Austria at domestic German prices: Telekom, Vodafone and resellers, O2. But they are a bit more expensive (around €10/1GB) and can be activated in a shop. Bear in mind that domestic data in Austria on an Austrian SIM is sold much cheaper (€10/10GB).

That's why we can't give any recommendation. It all depends on your needs and how much time, money and efforts you are willing to spend.
