We are looking at this to get for our parents who live in New Brunswick Canada. They would use it when they travel to us in New York. Does this work as an international device.?
I’m afraid the official answer is no: Service and Billing Q&A | Relay Docs. Official answer aside, a Relay would work in Canada on WiFi. It’s also theoretically possible to use a Canadian SIM in a Relay but that involves paying a Canadian service provider for that on top of paying for Relay service.
