(Buffalo, NY, USA)
I'm traveling to Canada from the USA this weekend. My friend lives in Canada and I would like to call him. Will I be able to call him?
I don't think so. Either last year (or the year before) someone I know traveled to Toronto and was unable to use her Tracfone to call me here in the US. I know you asked about calling someone else in Canada instead, but I suspect the answer is the same.
I hope you are using a smartphone so that you can use WiFi and something like Whatsapp or Skype instead.
