I plan to go on a long trip this summer in the northern Rockies. In the past I have always gone alone and without any kind of communications. I was thinking that getting a cell phone wouldn't be a bad idea. Last night I spoke to someone who has what is called a trac phone. Apparently you buy prepaid cards and use as needed. As you can tell, I've never owned one of these. I really don't want one buy I figure that it would be like a fire extinguisher, an emergency tool. I would contact home once every few days for a few minutes at best.
Any advice as to what would be a good model? I am not interested in using this with any kind of monthly plan. I just want it for infrequent use. Thank you.
