The Call Pass allows you to make unlimited calls from the United States to family and friends in Mexico and Canada, instead of paying a per-minute rate. To switch to the flat rate, just log into your Xfinity Mobile account and go to any line's Data Details. Add it from there. It costs an additional $10/mo for each line you add it to. All your calls to our North American neighbors will be covered under one, predictable monthly rate.

There are a few more things you should be aware of if you get the Call Pass.

When you add it to your line, it will retroactively cover calls to Mexico and Canada made during your current billing cycle.
It doesn't cover calls made from Mexico and Canada to the United States.
The $10/mo charge will recur until you choose to remove the Call Pass.
It's not pro-rated or refundable, no matter when you add or remove it.
When you remove it, it'll remain active for the rest of your current billing cycle. At the start of the next, it'll become inactive.
When it's removed, you'll go back to paying a per-minute rate for your calls.
Your Call Pass will come with you if you switch between data options.

Important note: The Mexico and Canada Call Pass is only available for phones at this time. If you have an Apple Watch paired to a phone with a Call Pass, the Call Pass does not transfer to it. Any calls made to Mexico and Canada through your Apple Watch will be charged under international rates.
