Did you know your phone has another CPU in it?
This is actually where the main secrets are on the phone and is also where unresolved privacy and security issues remain.
Hint.
This is where the eSIM is maintained.
So people's understanding of this is limited when responses are given to me about how eSIM is great.
If you actually understand what's involved, you wouldn't be so cavalier about taking the Phone OS maker's word about what's really happening on your phone.
