Understanding VoLTE and its implications.
Comments
-
VoLTE is basically VoIP over 4G LTE.
VoNR is basically VoIP over 5G NR.
Both should be easy to implement on any phone that is compatible to the infrastructure.
Where it gets complicated is when different carriers use different frequency bands for the service. It forces users to use phones that support those frequency bands (usually sold by the carriers).
I hope I'm wrong but it looks like a new form of carrier locking phones.

Why have a volte whitelist? If the phone supports volte shouldnt it just work?0

VoLTE is a service that uses various IP protocols to enable voice calls over LTE networks.
It takes the analog voice signal from the microphone and encodes it to digital data. It also decodes the incoming digital data to an analog signal that is sent to the speaker.
To prepare for transmission, the data is split and encapsulated in packets that implement the IP protocols. For reception the opposite is done (the packets are decapsulated and the data is reassembled).
The packets are transmitted and received over the 4G LTE network.
There are specific frequency band requirements that VoLTE-capable devices must meet based on the operator's deployed LTE bands. So if your VoLTE capable phone does not support the frequency bands used by Fizz it can't work.
There can also be differences in the codecs (encoders and decoders) used by operators. If the codecs are different it is the equivalent of speaking different languages.

This is very interesting, you seem very knowlegeable on this! My current phone is on the whitelist but the phone I am looking to purchase is not. Do you know, roughly, when 3g will be phased out?0 -
These are the planned shutdowns for the big 3:
Telus: December 2025
Bell: December 2025
Rogers: March 2025
So Fizz will probably be around the same dates.

Oh wow thats sooner than I thought, best to stick to the whitelist then! Heres hoping more phones get added soon1 -
I get the feeling that the whitelist will grow until then. Specially for newer phones.

I hope so! I know its unlikely but I hope they also whitelist some more niche devices as well. Like the suspiciously cheap Android phones on Amazon (some are actually decent!)0 -
I think it will be a business decision. So devices with the largest market share will be prioritized.

Makes sense. Although the current whitelist has TCL phones on it, and I don't imagine those are super popular, at least compared to all the other phones on the whitelist (Google, Samsung, Apple)0 -
Hopefully all the involved parties will eventually agree on a common set of protocols and codecs eliminating all the device restrictions.
Once a standard is established phone manufacturers can update their firmware to be compatible.

OnePlus can be configured to enable Volte with Fizz. It's for rather advanced users, but I made it work . You need Videotron mbn file from pixel 5 , follow the upload process and them enable profile in PCD tools.1

Hi. Does this require the phone to be rooted?

This is pretty great info! Any idea where to find the mbn file?0 -

This is a great idea. I just grabbed the mbn file, but I'm curious as to what device you used this on? I have a op7pro and a op12 as well. Can you point me to the pcd tools?0 -
Maybe you could try reaching him via private message. I'm curious about the procedure as well. I'm wondering if you need to root or just copy via ADB.

PLEASE support more phones with volte.
0 -
Maybe they have their reasons.
0 -
Yes, they sould support more phones!
0 -
"Volte" is an industry standard, right? Whether they are on any phone, it should work, at least those that support the right frequencies, right?
0 -
Yes most of the new phones support Volte but the phone carrier might choose to not support a phone So even if your phone has it it might not work because of that

Ok, thanks

You're welcome

I wish Fizz would tell us what it takes for a phone to be certified (in technical terms).
0 -
Yes it would be nice, I would also like to see more phone on the certified liste
0 -
If they explain what it takes maybe we will know why the list is limited.
0 -
Yea, beacause there's not many brand on the list
0 -
They will need to expand the list if they want to remain competitive.

If a OnePlus 8T KB2005 is certified on AT&T does that mean that roaming volte in the USA will work as long as I'm connected to ATT?
Or is it that fizz has not certified so even out of luck on ATT?

Hello. I was wondering about the volte situation for a Canadian "W" model Samsung S10
If Fizz does not have this model certified for volte but AT&T does (I checked the most recent whitelisted phones for AT&T), will this device's calling function work when traveling in the US with an appropriate Fizz US plan?
0 -
It should work as long as you connect to AT&T.
You may also want to check with Verizon and T-Mobile to see if it is also compatible with them.
