I want to have a shitload of crypto and let everyone know about it... where do I post my receiving address...? 😅

Anyway, my point was more about not using a SIM as a security mechanism, ever. It wasn't designed as one, and still isn't.

As for being a target... something like 2 years ago, I had a chance to get a glimpse at a C&C panel for some malware. It didn't bother checking your balance, just vacuumed all and every password from every app on an infected phone, along with all sorts of data about the phone, SIM, SIM2, etc. Cloning a SIM is so easy, they'll do it just to get your $50 worth of NFTs.
