Loud and Clear Here!
Before you travel to Canada you need to contact your carrier customer service and have them add the international plan I think its called and you should be able to make and receive calls back to the US. I would ask them how much it will cost, it varies I believe. But I know it can work, you will just need "international" option to work. Well I guess I should say I know this is possible with verizon and with cingular, not sure who your carrier is.
