I don’t recall doing that with a Hofer SIM card. However major other networks go a longer way recording who you are.

Then you probably bought your SIM before 2019-01-01. Old SIM cards will have to be registered until September or they must be deactivated.

I bought a burner phone in February (cash, no ID) and there was a HoT-SIM with it. I didn't try using it though.
