Slightly off topic: is there a way to tunnel internet over the phone system on a smartphone in the event that phone works but internet doesn't?

Probably with a dial-up call but you’d be limited to 2400bps: https://superuser.com/a/748163 https://superuser.com/a/748163

  Thanks for digging this up. It is quite a bit slower than I expected. At 2.4kbps, it might be enough for ssh.

    Just don’t try to read a man page and you’re good to go :)

It's built into iOS: https://support.apple.com/en-us/HT204023 https://support.apple.com/en-us/HT204023 A Personal Hotspot lets you share the cellular data connection of your iPhone or iPad (Wi-Fi + Cellular) when you don't have access to a Wi-Fi network.

  That still requires cellular data/internet and not just voice.

    Oops. I misunderstood “the phone system on a smartphone” to mean the smartphone’s cellular network, not using the smartphone as a modem connected to a landline.

You could use Slow Scan TV. There’s an iOS app to try it: https://apps.apple.com/us/app/sstv-slow-scan-tv/id387910013 https://apps.apple.com/us/app/sstv-slow-scan-tv/id387910013 Never did IP with it, but i worked with a team that jerry rigged this to transmit some telemetry from a remote location where external data access was cutoff for several weeks using portable radios.

  I would love a youtube/vimeo/whatever video on this. And someone publishing regular SS pictures like news footage or something otherwise particularly relevant if I was somehow in the middle of nowhere with an HF radio and an iphone.

    It would be tough. More like a virtual flip book than a video! In our case, we embedded some data in a QR code. It was one of the more fun little projects but only marginally practical.

We used to call that a 56k dialup modem and when we used it it wouldn't be long until our parents would scream up the stairs "Get off the internet, I'm expecting a call!"

Oooooh... a smartphone coupler for a dial-up modem? Take my money! https://upload.wikimedia.org/wikipedia/commons/e/e5/Analogue_modem_-_acoustic_coupler.jpg https://upload.wikimedia.org/wikipedia/commons/e/e5/Analogue...
