I'm 80 years old and don't own a "smart" phone. I have a simple flip phone. I have a leather case attached to my belt, and that's where it sits when I'm riding.
not even a flip phone for me, just one, attached to a copper wire to a converter box from there, fiber optic, no answering machine, either I am here or I am not, no voice mail, no texting me
I had enough of phones before I retired
