I am traveling to Canada soon and have added Travel Pass to my plan for my Galaxy S6. First, while I am in Canada, will people in the U.S. (family, friends, etc.) be able to call or text me as usual or will my number be treated as though they are making an international call?
Second, I am a bit confused by the dialing instructions. In order to call or text anyone in Canada, will I need to add a "+" before the number for both calling and texting? Or just for calling? Conversely, does someone in Canada need to do that to call or text me?
