Hi @Phil 

The European pass works in the same conditions as Easy Roam.

Using data, calling and texting can be used in the country you roam and back to Canada, without additional charges.

If you call or text to another country other than the one you roam in and Canada, then you will get charged additionally.

Dialing +1 in front of the Canadian numbers you want to call should allow the calls to go through. 

I hope this helps :)

Thanks very much! Answers my questions.
