I’ve carried a cell phone for about 10 years, and I barely ever use it. Between Twitter, IM, Skype, and Google Voice, I could conceivably shut if off completely, and never know the difference. The only remotely regular phone calls I make are about once or twice per month to my parents. Because of that, I use probably less than 75 minutes per month. On top of that, I’ve had texting turned off for over a year, since no one knows my cell number; everyone has my Google Voice number. So if someone texts me, it comes in via Google Voice over my data connection. And with wifi at home and at work, the places I spend the majority of my time, I use very little data. Despite all that, I was paying about $80 / month on AT&T’s lowest minutes plan (500 / month), no texting, and 2nd lowest data plan (2GB / month). I don’t need all that.
