There were no included calls & texts back then.
There was a real cost associated with contacting someone.
Let's bring that cost back

I still use ringtones and never put my phone on silent.
I got a new number & only gave it to a select few people.
My other number goes 100% unanswered. It's unusable.
That's a good idea. I think I remember reading about that strategy in one of Tim Ferris' books.
If a number is not in my contacts, I don’t answer.
I also don’t use voicemail - why would I call a machine to hear a recording you left me when you could have just sent me a text? Why waste my time like that?
