It’s bothered me for a long time that movie studios seem to think the only story worth telling about a superhero is the origin. You get a trilogy if you’re lucky, then back to another origin take. It would be like only ever running the pilot of every TV show even though they’re designed to set things up for an extended run. Or, I don’t know, remaking the prologue of Les Misérables over and over again without ever going further with Jean Valjean.

BoingBoing explains why SMS messages are more likely to get through than phone calls or mobile data during a large emergency. (Short version: They’re async, so the phone or tower can retry later, and they’re momentary, so they don’t tie up a channel like a call would.)

The article doesn’t bring it up, but I’d add the magnifying effect of social media. If that SMS message happens to be a status update to Facebook or Twitter, you can tell a lot of people outside the area that you’re OK (or not) at once, even over congested airwaves or wires.

Update 2024: I wonder how well RCS fares under the same circumstances, and how well it falls back to SMS. Especially since it looks like fallback is an app feature, not a service feature, so I can imagine some third party apps forgetting or not bothering to implement fallback.

Also, the social media aspect no longer applies now that the networks have discontinued post-by-SMS.

I did this for a few months. I had a 40-mile commute that typically took 90-100 minutes outbound and 2 hours back. It wasn’t so bad on the days when I could catch the train halfway there, but usually the lot was full by the time I arrived.

It was horrible, and I moved.
