Is Wifi calling more private than regular cell calling?

Lots of carriers offer the option of making phone calls and sending messages over wifi as opposed to using the traditional method.

I'm wondering if that's more private?

On the one hand, you can always keep your phone with cell signal deactivated (if you're at home or work) and so you're not being location tracked that way, but Wifi is such a blackhole, I'm wondering if there are any privacy compromises you have to make.

Has there been research done …
