They are still anonymous without registration. This may change in the future as Austria has a new government. But for now, you don't need to show your passport or ID card.

Austrian SIM cards need to be activated in the country on the home network first. So if you order them online, they often don't work as long as you don't log on the home (not roaming) network.

T-Mobile and sub-labels have a mandatory own registration for their SIMs to be used in roaming. For domestic use, this is not necessary.
