Can't find any raspberry pi zero w's in stock, or any normal pi's for that matter. Looking for similar or compatible alternatives for a small low power toy project. Any ideas?

No calls, no voicemail, no email, no bluetooth, no apps, no touch. I only want to send/receive SMS. I envision something like 2-way pagers used to work. Radio network or phone network is not as much of a big deal to me, as long as I can interface with SMS.

What are my options? All of the pager service sites I found have broken pages and contacts, and their hardware costs 1996 money with AA battery slots.

By "modern" I mean things like this:

- encrypted transit, when using a gateway to send from radio to SMS.

- rechargeable via USB or solar, not AA battery swapping. AA is fine if it can be charged in device.

- microsd or some type of removable storage for contacts, maybe message storage

- 6 line screen instead of 2 or 3

- LED backlight or Indiglo type illumination of characters

- something e-paper like would be cool from a practicality perspective, but this would likely hurt the price.

- some form of water/dust/lint resistance would be a big plus.
