I have a Trac phone (or is it fone?). The only reason I have it is my car has 200,000 miles on it and I have roadside assistance. Just put the phone in the car when I drive.
Probably only use one or two minutes a month.
I forgot to mention that my Tracfone works off a Verizon tower.
For many years there was no service here at all, then Verizon built a tower only a couple of hundred yards away.
