I haven't had a working cellphone in months and I'm completely okay with it. Don't get me wrong sometimes it stinks not being able to look something up or directions etc without having wifi but for the most part, everywhere you go has wifi so It works out.
I usually have my cell with me when I'm out of the house but I seldom look at it. It's mainly just in case I need to look something up or one of my kids or husband needs me to pick something up. It's definitely a convenience but I don't feel crazy when I don't have it.
