@deepakkumar Yes it looks like you've bought add-ons which allow you to call internationally while in Canada as suggested by @GinYVR . You'll need to purchase the US roaming add-on (select which add-on is best suited for your travel, bcause there are 3 options). Also remember to buy them the day you are leaving because they are only good for 10 days starting from the moment you purchase.
Edit: You posted new info while I was typing this information, so you have the US add-on too, but remember the expiry dates for your travel. Also enable roaming on your phone and select either AT&T or T-Mobile when you get to the US.
