This should be far more secure and privacy friendly than a Sim card of a cellular connection. Why isn’t this done more often? What are the Pros and Cons. I bet the price is similar as well.

If you care about security, don’t put a Sim card in your phone.
Personally I don’t have a VoIP plan. For archaic services that I can’t live without and required a phone number, I use google voice or Skype. Its a vulnerability, so avoid if at all possible
Depends on what you mean by security… or privacy. You need to define a threat model before any suggestions can be made.
If you’re worried about someone hacking into your phone via an app, a sim card likely won’t make a difference.
If you’re worried about your location being tracked… that can often be done without a sim card or any cellular service on your device.
Then there are malicious carriers (or ones compelled by a government) that could track you without even having legitimate service activated. All phones at least in the US now are mandated to have (A)GPS receivers.
All depends on what your concerns are.
