Notin in the T&C's says you have to buy the phone form Rogers.
2. Do I need a specific device or plan to use Wi-Fi Calling?
To use Wi-Fi Calling, you must have the Wi-Fi Calling feature enabled in your Settings on a compatible Rogers device with an LTE SIM. You must also subscribe to a Rogers postpaid wireless voice and LTE data plan.
I think you found the whole answer in this - Rogers has basically told us in the terms and FAQ's that they support a compatible Rogers device. They don't clearly define that a Rogers device as being sold by Rogers, but if you read it literally, a Rogers device would be one that came from them, or they have agreed to allow on their network.
And it seems pretty clear in what we have been told that this is exactly what they are saying - no plans at this time to support phones not purchased from Rogers (guess that means a Rogers device).
It would be nice if they were a little more clear in the terms and FAQ's so purchasers can make educated decisions on their purchases. I may not like their decision, but it is their network, their support, and their corporate decision, and the only power we have on this one as I see it is to keep bringing it up, recognize that terms are written by lawyers and trained staff and are not always intended to be easily understood. But the truth is out there now and if you bought the phone, unless you are bound into a cancellation fees, you can walk, and if you are still on trial period, you can also walk.
It is kind of a statement on the principle of the whole thing. Hopefully people will find that Bell will support it and find out if Telus or other providers do so, or Rogers will change their minds.
It is as annoying to me as to anyone else.
Quick update ; I'm not sure what hapenned or when it hapenned but my non Rogers Pixel 3 now has VoLTE working without any action on my end. The only thing I tried (may have a link with this or not) is to disable then renable the "Carrier Services" app in the app settings. It may also just be luck or that Rogers changed something on their end recently ; not sure.
IMS Registration = Registered
Voice over LTE = Available
UT Interface = Available
Voice over WiFI (WiFI calling) remains "unavailable" however and even if it shows in the Phone Info settings "WiFi calling provisioned = Yes", when I try to turn it on, even after contacting support I get prompted with a "Unfortunately your accounr isn't eligible for Rogers Wi-Fi Calling" (and it is, I confirmed with customer service).
And I confirm that WiFi Calling now works for me.
After seeing VoLTE worked figured I'd give it another shot. While NOT being logged on to a WiFi netowrk (only LTE), I was able to flip the switch for Wi-Fi calling to "ON" and then got prompted with a page where I capture my e911 address, name (Etc). Once I did that I was prompted to go back to Wi-Fi calling to turn it on but it wouldn't turn on / work right away ; I had to restart the phone, waited 10-15 minutes and then flip the switch back off/on again, with Wi-Fi network turned on this time. I also got an email saying I successfully registered for Wi-Fi calling from rogers.
Just placed a first Wi-Fi call (shows up as "Wi-Fi Call" when you dial out in the dialer app) and worked flawlessly. Tried my voicemail ; also works. So there is hope people ; call and complain if it doesn't work for you.
darn still no luck here. Goes straight to the "sorry wifi calling isn't available for your device" you may be the lucky one on this front.
So I caved, returned my Google purchased Pixel 3 and bought a Rogers Pixel 3.
My Wifi Calling experience:
Was able to turn Wifi Calling on, provision my number, add my e911 address and seemingly have everything working. My Wifi calling seeming to work intermittently, however never 100% of the time, even when I would be on a strong WiFi signal at home.
Contacted Rogers, they walked me through a bunch of steps to try to figure out why it wouldn't stay connected continuously (including resetting my wireless profile in their system, activating WiFi calling on my number). After the end of it all, with it still no connecting continuously, the Rogers help agent went away for a bit to find out if there were any Pixel 3 specific issues with WiFi calling. They came back and said the following:
"Thank you for your patience. I have some bad news, unfortunately. At this time, Wi-Fi calling is not available for the Pixel3. It's a relatively new phone so this may change, but we, unfortunately, do not have an estimated support date."
This was on November 16, 2018. So I guess WiFi calling still isn't officially supported by Rogers, and who knows when it will be. It's really disappointing that Google's flagship phone doesn't get the same support as iPhone.
