There is basically no such thing as a working dumb mobile phone any more. All the old 2G and 3G ones are now bricked because the networks all cut over to 4G/5G. Otherwise what can I say, just avoid stuff with connectivity when you can help it. Also buy corded tools and appliances unless the convenience advantage of cordless is too great to do without. Otherwise you stuck trying to replace overpriced and sometimes hard to find batteries.

If something is completely FOSS then the software angle is less of a pain in my opinion. I’m still using a beat-up Thinkpad X220 that was made in 2011, but running Debian Bullseye on it. I’ll update it to Bookworm or Trixie when I get around to it. Point is that I can do that, while any phone from 2011 is a hopeless dinosaur.

Contacts and dialer should maybe be merged. It’s nice to be able to call someone and make notes in that person’s contact page during the call.

Is there some obstacle to writing them? Special SDK privileges or anything like that? Seems like a good thing to degoogle if possible.
