Well met, Georgia. I mean, I think it'd be pretty obvious how it did. The world goes to shit. Cell towers fall. What ones remained in tact eventually don't even matter 'cause there's no real place to access electricity. Except the places that got generators going, like my compound. But by that point, no one else has a phone anyway....so they're pretty pointless to have around. Best we got are some long distance walkie talkies.
