Can you post a screenshot of the add-on you have?

There is no " unlimited calling to and from us to Canada" add-on.

Calling from US to Canada is roaming. You either pay - Easyroam fee or pay-per use rate.

Your add-on is likely $15 US  Unlimited minutes? It's only from Canada to US..

You'd have to be more specific about it. It'd not very clear if you mean calling to the US while in Canada or calling while in the US. If the latter, its easy roam at 14 dollars a day to a maximum of 280 dollars per billing cycle… Wow they've really upped the maximum rate too.

There are old monthly add-ons for roaming but they're so old at this point I'd be surprised you were able to get one of them. We'd have to see specifically what you're referring to

@Snowbound The below is the add-on you have. It is a monthly add-on, so depending on the days in the month that’s how many it includes.
