Making calls in US

[Queen1]

Am I able to use my phone to make calls within the US and from the US to Canada for free with my current subscription?

If your current subscription is can-us or can- us- mx then yes you can. You also need a volte enabled phone on Public Mobile's whitelist.

If you are on the Canada-US- (Mexico) plan, then you can make phone calls for free from within the USA.
