I am visiting Austria and I ended up going with T-Mobile.

Process was pretty painless. I was able to figure out the plans using Google Chrome to translate the website from German.

For 9.90 Euros I was able to buy a pre-paid SIM card on the MEGAKLAX plan. For 14.90 euros they offer the SMARTKLAX plan, which is the same except you get 2,000 minutes & 2,000 MB of data.

It has:
1,000 free minutes to all networks inside Austria, while inside Austria.
1,000 free SMS to Austrian phones while inside Austria.
1,000 MB data while inside Austria

I went into the store and the person understood English so it was quite easy. I had written down that I wanted a MEGAKLAX SIM card. Paid my 9.90 euro. Stuck it in the phone and typed in the unlock code and it worked. It can be used as a Full-size SIM (not sure anyone uses that size anymore), Mini-SIM (most common) and Micro-SIM. I don't know if they offer Nano-SIM.
