Hi everyone - I'm going on a business trip to Ottawa next month and I'm trying to figure out what my options are with respect to using my American iPhone 6 in Canada for text & data in particular? The phone is on AT&T here, but I have gotten an unlock from them. I called AT&T and one guy said that my mobile share plan would include talk, text and data in Canada, but another guy said that's wrong and that I would only get that if I also had AT&T cable internet or DirecTV. He said I would have to buy their passport to get text and data and a discount on calls. I also have an iPad on AT&T's grandfathered unlimited data plan, but I figure my best option is to try using a hotspot from my iPhone. Would buying a pre-paid SIM once I get to Canada make the most sense? Thanks!
