OK, what the heck is a cab card? From what I gather it is much like a prepaid phone card for use with Qualcomm. Not all truck stops have them and not all even know what they are. I read the card that came with the previous driver of my truck. Of course, the card itself isn't there.
Also, there are various ways to recharge your card. I tried to sign up using my comdata card and it says it isn't authorized. I have not tried a credit card. I tried to look all this up online and my computer froze up. I'm going back to Qualcomm's website to see if I can find additional information.
What brought all this on was that I was stuck in a remote area of South Dakota with absolutly no phone service for two and a half days.
