Also you can buy add on by going to <My plans>, <Manage Plan>, < Add on> , click on International Call and enter either Canada or United States. ( they're in the same zone 1 )

Everything M T. wrote and

When adjusting your plan, it will only take effect on your next billing cycle. For the current cycle, you would need to get an add-on.

Don't forget the plan changes will only be active on the next billing cycle. If you need it right away, get an add-on as M t. mentioned.

One more thing to add: Adjusting your plan will only take effect on your next billing cycle. For the current cycle, you would need to get an add-on.

It's also probably best to change your plan sooner rather than later once the intro prices are gone it won't be possible to add options for cheap.
