A minimal phone, with an e-ink display and an alphabetic keyboard, that costs $400? Umm, that is confused.

Here is what I would call a minimal phone: https://www.gsmarena.com/nokia_3310-192.php

Unfortunately those are all now bricked by the 2G/3G shutdown and nobody makes a phone with a similar feature set (i.e. absence of everything but voice calls) any more. The Jitterbug Flip 2 comes sort of close but it still has Alexa and other confusing stuff, and you can't buy it without an overpriced subscription.

I've been looking for a phone simple enough to not confuse some of my elderly family members and those phones no longer exist. So I'm constantly the involuntary tech support for whatever phone they use. I think of buying a cheap Android phone and writing a kiosk mode app that has no access to anything except dialing the phone. Maybe someday.
