I called a couple of them that were nearby and a modem answered.

I'm not interested in dialup data services at all at this point in 2026. I have no remaining means with which to use such a thing. The last cell phone I had that could act like a modem got retired in 2009 and the last time I had a dialtone in my house was 2010.

But if I had to guess, then I'd guess that these time machines are still operational.
