That’d certainly be appreciated; I believe SFOS has now gone through all of the hoops it needs to be sold in the US hasn’t it?
my understanding is that it’s a rather significant job to enable VoLTE on new hardware platforms, which is why it’s not available on even otherwise current Xperia devices.
I do confirm - Xperia 10ii DOES work with Yettel in Bulgaria by the method bundyo showed out.
P.S. Евала, братле!
I just switched to Telia FI, and I couldn’t get VoLTE register even with my X10IV. It turned out that my SIM didn’t have VoLTE enabled although it was supposed to work OOTB, and the self-service app/pages doesn’t contain the switch to enable it either. So after a quick online chat with the customer service, I now have a working VoLTE. A good reminder to double-check the basics 
Switched to Vimla! (Sweden) on Telenor network and I have VoLTE registered on my Xperia 10 II.
Still no working mms, but that where the same with my previous provider Hallon (Tre network) as well.
My current setting as bellow:
it seems they either lied to you or something changed, cause on their website 10 II is officially supported:
It seems like it’s not working for me (Xperia 10 III, Serbia, Provider - MTS, Sailfish 4.5).
I think I did everything correctly as described on this page - Beta VoLTE on the Xperia 10 III, disabled by default
Xperia 10 III, 4.5.0.16, VoLTE registered, O2 DE.
With VoLTE I cannot sent out a SMS.
On T-Mobile PL (Poland) VoLTE registration is instantenous, but so what if it drops to 2G every now and then, giving voice quality of mid 1990s. It used to drop to 3G but now that T-Mobile turned off 3G network completely in my area, I end up with GSM connection most of the time (it’s not even 2G because during the call it doesn’t connect to the Internet, hence not even “2G” symbol but only signal level on the SIM card icon. Even if I start a voice call on 4G / VoLTE, most of the time after a short while, like 10 secs or so, it drops to GSM network and voice quality that sometimes makes it a challenge to understand what I am being told.
I don’t know if it is a SFOS / X10 III or network problem, but it makes the 10 III hardly usable for voice calls, at least on this network.
hello
it’s very strange as I mentionned here and here on various forums, plus here :
https://forum.sailfishos.org/t/old-4g-devices-french-volte-could-sailfish-help-me-a-bit/14782/7
where it looks like nothing at all in VOLTE is a norm/standard, where each ISP Provider in the world have to handly provide his settings to each manufacturer to transmit them in each phone for each software version.
it’s handly made as artisan things by “engineers” (who looks like to be) and makes me upset a lot, in a way where a comment at this :
says that VOLTE should be a mandatory duty of all phone manufacturers , for all LTE devices, to support each volte config of all operators around the world.
WRONG : they will never do it, MOAR sells like some people say.
in addition, free mobile get some three or four years of late, and now apple doesnt want to bring FM isp on iphone 5/6/SE2016, whom are supposed to work.
why they never made an automatic system for each provider, each manufacturer, each phone system software, to make it detecteed and automatic?
the volte norm/standard have for a “norm” only the name, it’s a disaster, in my opinion.
if others FR/EU people can have volte wworking well on their lineage/sailfish/other os working, it’s really a chance.
here in france freemobile said “samsung and sony replied that because of our few years late, they will never update their volte isp list, not for past devices, not for today devices, not for their tomorrow devices sold.” (1)
for me, it’s just going beyond boycott… if you have others idea, such as volte injection through adb or other hack…
thank you for reading
I edit, few hours later :
I tried to add several twitter links, six or seven, and because if two links maximum on those sort of forums, I had to reply three times, BUT the system killed me a a potential spammer.
that’s why Im hidden, hope its not for everybody :o
hello
just to know, does lately volte ISP could work with jolla?
Im wondering : how Fre Mobile is on the list, here in first post?
where sony denied/refused to update that ISP (from france the fourth one) to android phones (I dont know if it’s the case for newers), cause lineageos, whom looks likes to take it directly from there, doesnt have it included :
mcfg_sw/generic/euro/orange/vlvw/fr/mcfg_sw.mbn
mcfg_sw/generic/euro/orange/vlvw/fr/mcfg_sw.mbn
mcfg_sw/generic/euro/sfr/vlvw/fr/mcfg_sw.mbn
mcfg_sw/generic/euro/orange/non_ims/fr/mcfg_sw.mbn
mcfg_sw/generic/euro/bouygues/vlvw/fr/mcfg_sw.mbn
we have four providers. One is missing.
thank you for comments/suggesetions/observations =)

hi bro,
thank you for your reply
unforunately, no xperia nor jolla phone appears in those lists…
Earlier I mentioned Vodafone NL was working on X10II. However, since 4.4.0.72 it is inconvenient to use. SMS text messages won’t be sent. I am certain it worked before. On 4.5.0.18 it is not working either.
Xperia 1 IV (XWCT-754)
Xperia 10 IV (XQCC-54)
are report to work … not other…
So can we help made VoLTE working on Xperia 10 III (and other) on Sailfish for freemobile?
hey,
looks like it depnd of the modem firmware, for xperia its mbn files… but only for latest models, instead of what the norm asks : all LTE compatible models. And nobody complains (means not only on iternet…)
Provider: POSTEMOBILE in Italy. VOLTE registration not works.
Note: modem-config not found with this Provider
Provider: TIM in Italy: it shows up in S132.1. VOLTE registration not working yet.
Modem-config found under S132.1
X10iii’s - Android and SFOS do not work with VoLTE on any of the 3 carriers in NZ. (Several other people have tried with the 3 carriers, as well as me.)
My conclusion is that the phones probably don’t attempt to provision VoLTE in NZ
Using the app NetMon VoLTE shows VoLTE->Registration: disabled
Below is the carriers reply to me, to summarise it:
“…I have been advised that for VoLTE and VoWiFi to work on any carrier the device need to have the supported carrier settings … Yes, sometimes it is possible for the devices which are not in list but has generic VoLTE settings compatible to 2degrees network , to generate calls over 4G network.”
My question is now: How to either make the phone request provisioning (if it doesn’t)
or What information do I need to get from the carrier, and how to add it?
or Why does the SFOS version at least not have some generic volte setting?
Details:
I have two of the Sony X10III. One is an EU model running factory Android 12, the other an HK on running SFOS.
Using *#*#4636#*#* (on Android) tells me that:
Preferred Network Type: NR/LTE/GSM/WCDMA
VoLTE Provisioned NO
Video Calling Provisioned NO
VoLTE Provisioned NO
Wifi Calling Provisioned NO
Enable DSDS YES
At the bottom of the screen are buttons labelled
CARRIER PROVISIONING INFO
TRIGGER CARRIER PROVISIONING
These are grey and appear to do nothing.
So the question is how to “trigger carrier provisioning” or perhaps manually
enter the required data, either into the factory Android version or into an
AOSP version? (I have two of these phones)
The other was an HK import. When running factory Android 11, it reported
exactly the same using *#*#4636#*#*
Here is what the carrier said:
In regards to VOLTE and VOWiFi , I have discussed your query with one of our Senior Technical Specialist and Device innovation Manager. I have been advised that for VoLTE and VoWiFi to work on any carrier the device need to have the supported carrier settings and ideally be tested and approved by that carrier. We cannot guarantee the service on any handsets we have not tested. As Sony is currently not in contract with us to support these settings in their handsets on 2degrees network, we can not do much in this .
Unfortunately, 2degrees do not blacklist or whitelist phones from working on our network as long as the phone supports our network configuration. This is not unique to us at all as every network is different and the services behind VoLTE and VOWiFi can be quite specific (particularly VoWiFi). You can raise your concerns to Sony in this case as Sony pulled out of the NZ market several years ago .
In regards to the Blackview BV9900, Android 10 , Yes, sometimes it is possible for the devices which are not in list but has generic VoLTE settings compatible to 2degrees network , to generate calls over 4G network. For VOWIFI , the process is quite different.
(@AlanBreen suggested activating the card in a working mobile phone for some carrier , though my carrier did not suggest this. )
(n.b We still have 3G, and the first carrier phase out has now been announced. However rural 4G coverage was funded by the government, and it appears that these sites don’t have 3G - so you have data, but no telephone or SMS function)
Is there some way to find out the generic VoLTE settings that Blackview BV9900 has? Or for that matter any phone that works on VoLTE. Where do you find these settings?
The the next question is how does one enable them on another phone?
A1, Belarus. Cellular operator supports 4G calls, but unfortunately ma phone unable to register 4G calling in a network.
Xperia 10 II, Sailfish OS 4.5.0.19 (Latest as per today)

@hackman238 how do you managed to have such screenshot? I do not have such interface in my 4.5.0.19.
