Well I received my back ordered purple S9 today.
Unfortunately they will not. They never bring those models down here. It's not Rogers controlling this either. It's Samsung Canada.
That is why I never buy Canadian phones. I bought the Exynos version unlocked with 128G. You also get to have a better color selection and get patches much more quickly. I have been on the May patches for over a week now.
I can certainly understand the interest in our VoLTE and Wi-Fi Calling service. I can confirm that both features are enabled on if the device was purchased from Rogers.
In the case of devices purchased outside of Rogers, we cannot guarantee the full performance and service of devices that have not been tested on our network. One factor is simply because of differences in configuration. Although this information may not be ideal for your case, I do hope it helped alleviate some of your concerns.
