My phone is on silent, no vibrate, 24/7.
If someone calls and I miss it, I figure if it's important, they'll leave a voicemail.
Otherwise, I check my phone very frequently. But I don't want to be alerted in any way, shape or form, unless I'm expecting a call/text.
When I go to bed, my phone stays in the kitchen. I have a landline that will ring if anyone calls or needs me at that hour.
