This plan includes unlimited long distance/local talking and receive only text. No send text, picture text, web, or voice mail. You must buy a basic non-smart phone ranging from $30 to $70 in price. It is month to month (no contract).
Since you cannot send text then as parent you don't have to worry about your child sending text while driving. Also there is no web/internet so your child can't look at pornography while you are away. Finally with no picture text you don't have to worry about your child sexting.
