Freedom of speech is good. White supremacists or any other group ideological supporters will always find a way to communicate and share their message, regardless of the century, technology, or censorship. Frankly, doing this openly on X/Twitter versus some obscure unknown forum or encrypted platforn is a positive. Social media as a whole is susceptible to ideological campaigns from groups and other countries, not just X/Twitter.

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.

Gold and silver.
