Are you in North America? Which feature phone would you suggest? The Nokia 3310 was likely the only phone I was considering, but it’s ancient and 3G and doesn’t seem very future proof.
Oh, I’d forgotten that they made a new phone with the same model number in 2017.
Even Nokia’s website seems confused about it because it claims the 2017 3310 is a 2G (“GSM: 900/1800 MHz“) device. That can’t be true of even a low-end 2017 device. It wouldn’t even work on many modern networks without at least having 3G!
