@georgetakei Gather 'round, children, for I have a chilling tale to tell. Long ago, before cell phones were anything more than just a toy for the super rich, there was a technology called "Caller ID" and its advent shook society to it's core. Yet, even that was just a follow-up to the previous culture-shaking event, *69. There was a few years where you couldn't get Caller ID, but you could reach deep into the phone system and force it to reconnect you to whoever just hung up on you.
@georgetakei if your phone is off (i.e. on a plane), or you're out of service area (e.g. cave tour at Mt Shasta), there will be no missed call notification.
@georgetakei People who don't leave voicemails, or don't follow the missed call with a text, do not get called back. Can't be that important if you can't do one of those.
