For blocking I do understand it would probably get confusing if people's phones are dipped/sold/end up in other people's hands though.
It'd prevent someone from trying to call their chummer and being incapable of it because of a reason they might not be able to decipher for weeks. Not everyone wants to fiddle with the admittedly clunky apps feature (I don't even know how it works) just to have a conversation. With phones, it's always important to keep in mind that you're, more likely than not, not the last set of hands it'll be in. I believe, but don't quote me, you can sort of bypass this by dropping the phone, as if I remember correctly, it'll give you a busy signal if it's not in someones hands.
Don't quote me, I'm babby to this.
Getting jumpscared by phones too is our new future.
I mean, if someone's blowing up your phone irl there's no way in hell you're ignoring that. I've tried.
