The Light Phone 2 comes to mind: https://www.indiegogo.com/projects/light-phone-2. It's not available yet, and I've heard some complaints that it has too many features. But, it aims to be a middle ground between a smart phone and a completely dumb phone.

The second one. In the US they're a little hard to come by. Sure you can order something online. (There's a whole niche market of tiny dumbphones that don't claim to be made for prisoners, but are designed to be easily smuggled inside body cavities.) But their retail presence here is almost nonexistent.

Also, it's much more difficult to find one if you insist on a particular carrier. For example, the popular line of Blu dumbphones (which still have cameras) operate on 2G-only GSM, and don't work with Verizon, AT&T, T-Mobile, Sprint, or Boost (i.e. all of the major providers). You have to use something like StraightTalk or Simple Mobile (i.e. prepaid discount service, similar to Tracfone) to make them go.

Bought one. Physically removed the camera. Still has a browser and and app store, not to mention a builtin facebook app that can't be removed by the user. And the price point is around $60.

There's no reason for a bare-bones dumbphone to have any of that shit, or for it to cost more than $20.
