tl;dr; Just do it, it's an amazing hack for increased focus, productivity and peace of mind. I recommend

Personal phone -> A feature phone Business phone -> Smartphone if you're in primarily customer-facing role(e.g. sales, customer support)

My Story:

3 years back, I gave away my smartphone and switched to a simple feature phone. I had to get a smartphone for a duration of 6 months in between this period(when a lot of my day job couldn't be finished without accessing whatsapp groups/messages and travelling)

For my job as a programmer/founder, I prefer no smartphone at all and use following formula

1. For Personal Use: phone on feature phone 2. For Business Use: iPad with only business whatsapp, toto app, book reading app(and that too only when I am not able to lure any other team member to handle it for me)

Location services, cabs, all these things can be handled without smartphone. Although, it takes little longer and inconvenience but also gives an opportunity to live in the moment, ask people for help.
