I should probably get one for the car. Was waiting for a call out only version. VA sister says they're available.
Mine is call out only when I want it to be.
IOW, even if someone calls you, you don't have to answer it.
You can turn it off when you don't need it and you also have the ability to silence the ringer.
Mine stays off until I need it, or unless I am expecting a call.
What would you do with a call out only version if you needed help back in the boonies and your rescuer couldn't find you and had to call you for more detailed directions?
FWIW, I wouldn't have a call out only cellphone. I live in VA and have never even heard of one.
