My doctor’s office has my email and knows to use it. Half of the time I’m not even in the country where that phone number works.

I just buy 90 day prepaid SIM cards. At the end of the 90 days I’m usually in another country.

My Google Voice number is sufficient for authing to Signal, but I don’t give it out to vendors/services or use it for phone calls.

I never receive any voice calls to my SIM card itself. Anyone who would want to call me knows to reach me on Signal. Anyone else, I don’t need to speak to them.

Most of the time my voice conversations are in Google Meet calls, anyway. It’s almost always for clients who don’t like to type and would prefer to be synchronous instead of using their device’s built in dictation software.
