Making a steep change can be a good way to break into better self-control.

I loved not having a phone for a while, then used a tablet for a few things that were more convenient by app than website, in addition to a PAYG Nokia in case of emergency (in the car, or at home where I have no landline) and eventually bought a cheap smartphone in Amazon's prime day sale to combine those two functions.

But the result is that I use my 'phone' like a tabket: it's never in my pocket, and it functions as a phone only ICE. I'm not sure I'd have done that and stuck to it if the transition had been direct from daily 'normal' smartphone use. I was never 'addicted' any more than the average person, I've never been into Snapchat et al., but I suppose I was close enough to notice and harbour distaste for that trend.
