Not OP, but I also made the choice not to carry a phone (not even a dumb phone) because I don't want the inconvenience of carrying an interrupting device everywhere I go.

There's a phone at home and one in my office for emergencies, but other business gets done by email, on my terms.

I live in a (non-US) large city, walk or bike to work every day and don't own a car. We have a pretty good public transit system which I used to use a lot, pre-covid.

The biggest inconvenience of not carrying a cell phone was that I didn't have access to live bus and subway schedules, so I would sometimes take a suboptimal route to my destination.

My schedule is done on paper in a pocket schedule book that I always carry. I also carry a pen, a simple watch, a Swiss army knife, and a small flashlight, all of which I use at least once every day. I also always have a book in my bag, for reading while waiting for the bus, the doctor, or other things and people.

I look things up on the Internet at home.

I'm not saying I will never carry a phone, but it seems that not having a phone is the right choice for me at the moment.
