Stateside International Talk is $15/month and covers unlimited calls from the US, Mexico or Canada to landlines in 70+ countries and mobiles in 30+ countries. Without the add-on, calls fall back to per-minute pay-per-use rates that vary by destination — T-Mobile's own rate chart lists Canada at $1.00/min, with many destinations higher.

Kinvo vs WhatsApp
WhatsApp is Meta's messaging app, with well over two billion users worldwide. Its voice and video calls are free and end-to-end encrypted, and they travel as internet data rather than as phone calls. That is also the limit: a WhatsApp call can only reach another WhatsApp account, so both people need the app installed, registered to a phone number, and online at the time.
