What is the meaning of the coverage Canada+US?

Matthieu Dorzin

If I choose a Canada+US coverage, will I be able to use my phone when I'm in the US?
or
does it work like SMS, which I can call any US phone numbers but I have to be in Canada for me to do so?

You'll be able to use phone in US ( with some restriction https://fizz.ca/en/faq/partner-networks )
