In fact, I didn't downgrade to this from a smartphone. I've never had a smartphone with phone service, that I carry around with me or use. Maybe I don't know what I'm missing. Maybe I don't want to know.
The only real thing I wish I had was an easier way to carry on text conversations. Typing on a phone dialpad is not very fast. Most of the time I can use Verizon Message+ which works in a web browser and lets me send SMS from my own phone number. But when I'm not near a computer, I can't do that.
