Just to confirm, in late April I bought two Yesss SIMs (one phone SIM and one data SIM) from a Hofer store and they did not ask for ID. It was obvious that I was not Austrian...
This is not a guarantee as my experience is that such policies may not be consistent from one store to another. But at Hofer they were just sold by the lady at the checkout till, not some special office, and she didn't seem to have any concern other than trying to understand my half-remembered German.
