Nearly everything that both requires a phone and disrespects my privacy has been work-related, so using 2 phones has been a solid choice for me.
The work phone has a sim from a mainstream carrier and only gets powered on while at work during work hours. Maybe I’m spoiled that my workplace tolerates this arrangement. I couldn’t imagine having to be reachable any time of the day. I didn’t intentionally buy a separate phone, it’s just my old phone repurposed.
The personal phone has an “IoT” SIM which can be purchased non-KYC where I live. All FOSS apps and a personal number via VoIP.
I know it isn’t by any means airtight, but it gives infinitely more peace of mind than just trusting whatever sandboxing mechanism available on one device will be sufficient.



Anything that requires PII in a separate browser that doesn’t clear on exit. General browsing on my main browser, which clears data on exit, except for a small list of exceptions. It doesn’t defeat non-cookie fingerprinting, but I at least get rid of all the cookies that I don’t want.
