Well, I certainly hope that is a typo. My wife and I are literally changing to T-Mobile tomorrow (from AT&T) and this was part of the allure for me (Mexico)

I see the fine print you mentioned and understand the concern.

However, if I just go to T-Mobile.com and scroll down the page there is a clickable link to get more info on international which takes you here:

https://www.t-mobile.com/optional-se...O8ZG4F0WFY7955

If you scroll down to the section where it says "Coverage in 3 countries for the price of 1" it still states (and not in fine print):

"T-Mobile has expanded its coverage. Now unlimited calling in the U.S., Mexico, and Canada is automatically included with our new T-Mobile ONE™ plans. Plus, get 4G LTE data and unlimited talk and text in either country. All at no extra charge" (emphasis added)

So, hopefully that is still correct and I'm hoping what you found was a typo.
