Not sure how many of you on here are in Canada, but this seems like a good place to ask. For those that have upgraded to iOS 9.1, do any of you have VoLTE working? You can tell by placing a call and look to see if it switches to 3G or not. Alternatively, if you go into Settings -> Cellular, there will be an 'Enable LTE' menu you can go into. If it says 'Voice & Data - LTE' then you're in the same boat as me. Their tier 2 support says the 6 is compatible, but so far I can only find people who are on the 6s/6s+ that have gotten it to work. Thanks guys!
