At the moment, VoLTE is only available for iPhone 7 and 7+ models either, BYOD or purchased from Videotron, since its launch. We would like to reassure you that we are working to offer this service on the largest number of certified compatible devices. Other models will be eligible in time but we have no official information that can be confirmed at this point.
We are sorry about this inconvenience and thank you greatly for your patience.
We try everyday to get back to you guys with the more specific and «human» answers possible. It's important to understand however that we are sometime bound by the information the business is willing to divulge publicly.
I think one of the strengths of the Community is that all of you can chime in with the information you have and help answer the questions of other Community members.
I'm proud of the Community we are building and I will thrive with the help my moderator colleagues to bring you the most up to date information possible.
Hopefully this sheds a bit of light on the situation.
