The long distance rates vary by country. There is a $5 feature which reduces the international long distance rates. To give you an example, if calling South Africa without the aforementioned feature, the rates are $1.45 per minute. With the $5 long distance saver, the rates would be $.02 per minute.
If you'd like to know the rates of any other countries, they can be found at http://www.rogers.com/web/content/add-ons?asc_refid=addons. Click on "Long Distance Rates by Country" on the right towards the middle of the page. From there, select the country you're looking for. Once selected, it will show you both the regular rates and also the discounted rates with the $5 International Long Distance Add-On.
