Does Anyone Use their Phone without a SIM Card?

This is something I've been thinking about for a while. I've decided to get a Pixel with GrapheneOS as my next phone and I'm trying to decide the pros and cons of putting a SIM card in it. Convenience vs privacy, public wifi with a VPN vs using phone data, etc.

I can't get a SIM card where I live without ID and I'm looking to reduce being tracked as much as possible. Does anyone else do the same thing?
