KCTC only bills long distance for AT&T and our own 2 Carriers. It is best to pick a Long Distance plan that fits your needs. If you use a large amount of long distance, look for a plan with a small monthly charge. If your long distance usage is infrequent, then a plan with no monthly charge might work better for you. These plans usually run about 14¢ to 15¢ a minute, depending on carrier prices.
