Why only popular phones authorized on voLTE compatible list ?
Just learn from 2025 july my phone will not works on Fizz anymore because of this, but i am told i have to buy a preloved phone from Fizz (ha!...) but when i'm planning to buy another phone which is showed at 5g connectivity : FDD-LTE (interdictions 1/2/3/4/5/7/8/12/13/17/18/19/20/25/26/28A/28B/66), TDD-LTE (bandes 34/38 /39/40/41/42), 5G NR (bandes N1/2/3/5/7/8/20/25/28/38/40/41/66/77/78) then it is also, as my current phone, prohibited on the famous authorized phone LTE list compatible .... why are you guys only authorizing popular brand smartphone to go to voLTE and no others 5G phones ??

Hi @Marc86
I believe that this is a problem with the certificates and/or codecs, since I don't think that they tested the phones and they excluded after, or they need to pay a royalty to get the possibility to use
When Fizz is provisioning the VoLTE on our phones their hide the VoLTE options, I don't know why

I believe that each company uses some different frequencies for the VoLTE. In this way a phone might be good for one company and not good for another.

You should check the Fizz frequencies and the one supported by your phone.

A phone configured with LTE network preferences must support the dual frequency 1700/2100 MHz depending on the site https://fizz.ca/en/faq/compatible-devices

where can I find the fizz frequencies?
4G bands 7, 13, 66.
5G bands n66, n71. They may add n77/n78 at some point.

That applies to the LTE network in general. It has nothing to do with VoLTE specifically. If you have LTE data and the phone has VoLTE support, all the technical prerequisites are there. What makes it complicated is a configuration profile is required for each individual network operator. And that phone manufacturers and network operators have unilaterally decided not to allow consumers to do this configuration manually. If you remember the early days of packet switched data on mobile networks, you may remember a long page of configuration options where you had to set up APN and MMS settings for data access. Same thing. Only difference is that consumers could / had to configure it themselves back then.
On iOS devices, you get these configuration profiles over-the-air, you may have seen the "Carrier Settings Update" popup, that's exactly what that is.
Not sure exactly how it works on Android devices these days, at one point the configuration profile(s) seemed to be part of the firmware. Which means, for VoLTE and VoWiFi functionality, it mattered not only what phone you had but also what network provider's firmware was running on it.
And that's really all this ominous "VoLTE certification" is. Whether Fizz is providing and testing a configuration profile specific to their network for a particular device's firmware or not. iOS users tend to have it a little easier as to the best of my knowledge no network specific firmwares exist for iPhones. So any iPhone bought anywhere will have VoLTE/VoWiFi support on all networks. And configuration profiles should be universal across all iOS models. So less effort for more coverage.
