flip phone
Almost all such phones are actually smart phones in a flip phone Edgar Suit. Especially if it has maps or YouTube or any kind of an App Store. I see a crapton of flip phones that run Android, which has all sorts of Google spyware piggybacking along.
I think there may be only two or three dumb flip phones or feature flip phones left on the market, and IIRC two are locked to specific networks.
If you want a bona-fide dumb phone, you might be limited to something like the rotary un-smartphone.
Will have to look into that, thanks.
One of my key implementation requirements, however, will be resiliency, which means simplicity will be a core feature. The more “moving parts”, the easier it will be to break.
