Good evening & welcome to the Rogers Community Forums @goldberry,
It's always a good idea to clarify about any potential charges instead of incurring any, especially on the first invoice. As long as your wireless plan includes unlimited calling and messaging you will not be billed for any incoming calls or messages. However if you were to send a text or call a US/International number there will be a charge. Charges vary depending on the location you call or text.
Thanks that does help as I was concerned that spam calls and texts originating from a US/International number would create a charge. Is there a quick url that indicates costs of text and long distance charges going out of Canada?
You can find the pay-per-use as well as long distance preferred rate options here. Once you are on the long distance page, please click on U.S & International Preferred Rate to view a specific country's charges for mobile and landline numbers.
