A few months ago I bought a Nokia 105. It was $25 on Amazon.

It makes phone calls and text messages. The battery lasts almost a month. My wife can call me in an emergency. I wired up a few work outage alerts with IFTTT. That's about it.

The best part about it is that it leaves me alone. When I turn my smartphone back on, it's incredible to see the barrage of worthless notifications that would have distracted me throughout the day. I no longer check my phone aimlessly because there's nothing to do.

I agree with this suggestion. I have not regretted having both a smart phone a dumb phone I can use when I want to untether but also still be contactable in emergencies.

Set all potential emergency numbers to be important. Set your phone to no interrupts except for those contacts. If your phone doesn't make a noise, don't touch it.

If you're not blue-light staff it does not seem like a rational fear. Smartphones has made us all control freaks. I think we need to practice giving up control.
