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.

1st world countries have myopia. 3rd world countries do not. People in 3rd world countries that are emerging into 1st world countries will develop myopia. Less exposure to the full brightness of the sun in the infinite activity of the outdoors and increased time spent indoors with indoor lighting and stagnant vision environment leads to myopia. The eyes are the most intimately connected organ to the brain - perhaps you should rethink your vision lifestyle. Is it good for you to be stare at a webpage with increasingly larger fonts on a smartphone 12in/30cm away from your eyes? Probably not. Eyes are supposed to constantly be moving (saccade) and should not be dry. Great eye health is a great life. Sincerely, someone who has proactively one from -2.25 in to -1.75 in both eyes in 9 months time.

In real world application, increased efficiency doesn’t decrease energy usage nor decrease labor required to live. Tech has gotten more efficient since the industrial revolution, but demand for technology has increased exponentially, energy use is astronomical, and workers still work more hours.
