Sim card w.o. phone number

So, I recently got a lot of scam calls and I was wondering if there was a market for "mobile data only" sim cards. So basically Sim cards which do not provide you with a phone number and cannot be targeted that way.
My idea would be to mainly use a "data only" eSim and keep a physical prepaid Sim I can use whenever I need to call somebody or be available by phone. Possibly also the other way round. …
