The DuraXE does look like a good phone though it has imho non-dumbphone features like wifi. I guess I better check its network coverage and will look into it. According to PC Mag it runs Android 5.1 under the covers, which is a little bit scary to me.
A Baofeng ham walkie talkie is about as rugged as a typical "rugged" phone and costs around $25 so I don't see why there's no phone in roughly the same format. Until the 2g shutdown you could buy 2g phone modules for a few USD, that had some analog audio wires and some control lines and a power wire, so you could make your own phone around it pretty simply. Sparkfun had a product that was one of those built into a vintage rotary phone. I don't think they have those modules for 4g or 5g but I should look again, I guess.
Added: aha re 4g modules, this is $60+ but looks interesting, and makerfabs has some other neat stuff:
I do think that more and more people are starting to want less intrusion by the devices in their life so I wouldn't be surprised if a true affordable dumb phone enters the market in the next few years.
Everything else, such as camera, messaging, calendar, contacts (except maybe a few predefined contact buttons that are always there), etc., should all be absent or inaccessible. And, I have gotten the person a digital wristwatch for xmas, so that might relieve the clock requirement.
Added: that people are willing to pay premium subscription fees for a sufficiently dumb phone really shows that it's a desirable product and regular vendors should be selling unlocked ones.
