The Motorola F3 is that phone, if all you care about are phone calls (it can’t really do SMS). You are probably better getting a similar era Nokia though, as the battery life was about the same and they were a lot more functional.

I bought a Motorola F3 phone like 10 years ago for relatives.

E-ink display, good for elder people, you can drop it from 100 feets height, or run a tank over it, drop it in a pool. It will survive.
