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.

    You can keep your cell number with jmp.chat. Call over wifi or data. They offer eSIM. View text messages on any device/program with XMPP support. 2FA works 100% like normal unlike VoIP. All data, calls, texts are routed through their VPN first, then the cell network. Any other inhouse XMPP chat not going to networks stay within XMPP. I have no affiliation with jmp.chat, I am satisfied with the service.

          SIM cards are a computing device that can execute closed source code on your device, sent from a cell tower

          Most of the zero days used by NSO Group that were reported by Citizen Lab only worked if you had a SIM card. By eliminating SIM cards, you decrease the surface area of attack by magnitudes

            Thanks for enlightening me. That is certainly concerning. I am not knowledgable enough to say if eSIM would be outside the scope of that attack. There are some differences in how the tech is implemented, but heck my eSIM still connects to the cell tower at the end of the day (and to multiple carriers, at that, unlike physical SIM). If there is a surface area, there is a chance for attack vectors.
