If you receive a chirp inbound from a telus you will be charged international DC at approx. .10 a minute for your reply and if you initiate the same holds true....Doesn't work any better if you get service with them and use it on there network, same deal ..it's the tower your attaching to that determines the cost. Still cheaper, faster, and more convinient to go Direct Connect, and if you have to talk with those who have it to get the job done than I don't see an easy solution....Sorry, Jess
