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.
What security risks are you considering for physical SIM?
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.
I can see this being useful for young children who need access to information but whose parents don’t want them in creepy pockets of the internet.
Try this from Sopranica. lemmy.ml/c/sopranica
That is true, but there is a good reason. For example, you may call 911 in North America without any cell plan, or without a SIM. As you long as you are within physical range of any cell tower (whether your phone shows bars or not) the 911 call will go through. This is required by law. So, like your quoted text indicates, 911 calls would just need to be routed through your phone’s native dialer instead of, let’s say, Cheogram’s dialer (jmp.chat’s phone/message app).
