Smartphone plans are relatively cheap now.
It is not a status symbol anymore except possibly the highest end models. A lot of them can be obtained for under $200 used/new. It is the affordable, portable and useful calculator, camera, web browser, computer, organizer, communication, entertainment..... etc for everyone's life from homeless to uber wealthy.
It is everyday life in 2019. Event the remote areas of our planet with no electricity have them to stay connected.
A smartphone is the easiest avenue to a job even collecting when you have little else, because you look over job ads, apply to them, write email, and answer calls with voice mail anywhere.
I was laughing when I called a person to return something wife borrowed from local farmer. I asked if he was home and he stated he answered the phone so of course he is. Did this old dude realize people rarely have landlines when he made what he thought was a sarcastic comment?
