In Israel, around a million ultra-Orthodox Jews have specially made "kosher phones" that only make phone calls[1]. This is for religious reasons (with, it must be said, a not-insignificant amount of social pressure.) Full disclosure: I am one of them, while managing to be CTO of a company with around 100 employees. If people need me, they have my phone number. The phones tend to be recent model feature phones with custom firmware that only allow phone calls. I have to say, I very much see the benefits for concentration, focus, and general well-being. Sure, occasionally it's a pain, but the benefits far outweigh the costs. The phones generally cost less than $100, and last way longer than smartphones do (I've had mine around 6 years, the battery lasts a week on a single charge, and upgrading won't get me any new features!)
