I'm thinking of getting my tween her first cell phone.

Looking at Tracfone's which you buy minutes for. 1 minute of talk takes 1 minute. 1 text message takes 0.3 minutes. Minutes are gone, you need to buy more.
Main need for phone is to call for rides, when on metro and delays, etc.
I want to avoid having the constantly texting through dinner teenager (that my nephews have become)
