I have a cell that now runs me 20.00$ a month-I don't use many minutes at all,mostely have it for my daughter to text me when they're on the road and for if something goes wrong when I'm out and about on "Buzzy". I need something that will charge me only when I use it..Does anything like that exist? I'm not too good with tec stuff (haven;t figgered out how to use the dvd player sence I got cable! ) so no need for it to sing or tapdance. Any help would be appreciated.
