Re: and off-grid paranoiacs
"...easily confused relatives"
Unfortunately, any & every mobile can be confusing for some. No matter how simple the interface, it's still a mobile phone, and therefore something to be feared.
Residents of care homes can sometimes find themselves cut-off from the outside world if they have no landline and yet are unable to use a mobile (smartphone or dumb).
A brilliant recent "invention" was a phone that looks and behaves exactly like an old tethered phone - one that in days gone by would have sat on a table in the hall or at the bottom of the stairs.
This baby contains a SIM instead of being wired to the phone network, but is instantly familiar to the older generation. Genius.
