This worked for me for Comviq (Sweden):
- SIM config ID: S55.3
- Config file:
mcfg_sw/generic/euro/tele2/vlvw/swe/mcfg_sw.mbn

For completeness (since I refer to this page on the VoLTE provider support page)
This is what I did to make Telavox to work on my Xperia 10 II.
I put in my complete SIM card number since I don’t know if a particular prefix should be used but I think someone with more knowledge of these things can use this as a starting point at least.

@flypig The Jolla Shop still claims that Xperia 10 II does not have VoLTE beta, although it does. Shouldn’t it be updated?

You’re right, it should! Thanks for pointing it out; I’ll raise it on Monday.

This is still to be done, but I’ve not forgotten about it.
Thanks again for pointing this out @direc85. The Shop page has now been updated. Please say again if you notice anything else.

Has anyone in the US figured out how to get VoLTE working on the 10 ii with AT&T based service? I was successful in getting T-Mobile service to work using hackman238’s instructions (modem config). I have a Red Pocket AT&T SIM (GSMA). Data and text messages work, but no phone calls. VoLTE does not register (continues to blink). I do not have to worry about the AT&T whitelist because Red Pocket seems to bypass that even though they are using AT&T service. I believe the phone just has to be configured for AT&T similar to what was done for T-Mobile. If someone can help, it would be appreciated. Thanks.
I’m also in the USA and use a AT&T backed network (PureTalk) using a Xperia 10 ii. While text and data work as expected, calling doesn’t work at all. I also get the same “VoLTE not registered” with a continuous blink. If anyone knows how to fix this issue, please share.
I also have a non-VoLTE-registering Hallon. How did you get the correct modem.conf into the right place on your phone?
I tried to suss out what I needed to do based on your post, but while I’m able to create a directory to hold a modem.conf file, I’m not sure what I need to do to get the correct Swedish “hutch” configuration into there. I saw that there was an earlier hutch reference, and thinking that perhaps “hutch is hutch”, I gave that a whirl, but no joy getting VoLTE to work yet.
What I tried…
[root@Xperia10II-DualSIM ]# mkdir /vendor/oem/modem-config/S9105.1
[root@Xperia10II-DualSIM ]# echo -n "mcfg_sw/generic/euro/hutch/vlvw/uk/mcfg_sw.
mbn" >> /vendor/oem/modem-config/S9105.1/modem.conf
As of now I don’t remember. I will have to retrace my tracks…
Will be back.
Thanks. Much appreciated!
As a start as su/root:
getprop persist.vendor.somc.cust.modem0
Gives me the ID: S9105.1
cd /vendor/oem/modem-config/S9105.1
Gives me: No current config for this ID exist.
As I knew from the @tw1 hint that I should look for “hutch” as the name for 3/Tre/Hallon I did a check:
ls -l /vendor/firmware_mnt/image/modem_pr/mcfg/configs/mcfg_sw/generic/euro/hutch/vlvw/swe/mcfg_sw.mbn
As this did exist I went on creating a S9105.1 folder:
mkdir /vendor/oem/modem-config/S9105.1
Next create the config file:
echo -n “mcfg_sw/generic/euro/hutch/vlvw/swe/mcfg_sw.mbn” >/vendor/oem/modem-config/S9105.1/modem.conf
After this i rebooted and where able to enable VoLTE.

Yesterday i switched from Hallon to Vimla! (both in Sweden) hoping to be able to get mms working again.
Had some real issues getting the proper settings for mobile data and mms, so I have been at 3G only until this afternoon. Currently still no mms but at least I’m on 4G again. Have a look at the attached pictures for my current settings.
When I had my 4G connection working i did replace my current “hutch” with “telenor” as Vimla! is running on the Telenor network.
echo -n “mcfg_sw/generic/euro/telenor/vlvw/swe/mcfg_sw.mbn” >/vendor/oem/modem-config/S9105.1/modem.conf
After a while i had VoLTE enabled.
Not quite shure that I actually had to replace the file as I got VoLTE enabled with a Telia SIM without replacing the file. Maybe they are all included in each file… Perhaps someone here knows?
Where not able to test the mms functions with the Telia SIM as the preloaded amount where almost zero.
Yo @werdinand I got fed up with Telia today since they were really unhelpful forwarding anything to a technician to check VoLTE logs of any kind, and picked up an Elisa SIM card.
Unfortunately, Elisa can’t connect either.
I hooked up S253.1 with mcfg_sw/generic/euro/elisa/vlvw/est/mcfg_sw.mbn just like you describe, but it just won’t register.
How does it work for you, what’s special about your phone, or SIM, or…?
Tried SIM1, SIM2, nothing, won’t register.
I’m still at Telia and tried Elisa with a test SIM. I have reflashed my phone (last update went wrong) and can’t check the settings but as far as I remember, there wasn’t anything special. At the moment if I check the modem settings I get S252.1, have you tried that with SIM1?
S252.1 is Telia, and that wouldn’t work either.
Are you saying your VoLTE is also working on Telia EE?
Nope, Telia EE VoLTE doesn’t work.

Finland, I assume?
I just had Elisa SIM which I switched to Telia. With Elisa I used VoLTE successully with my X10III, and Telia now works too after I contacted the customer service to have them enable VoLTE for me. You can’t do it in the self service for whatever reason.
The same here: VoLTE works on my Telia account (after reading your post, I also called them to ensure that VoLTE is enabled for me). I have none of the problems reported here in the Forum. SMS/MMS come and go, hotspot works, mobile data works (well, I have not been roaming recently), and phone calls work.

Estonia + X10II. I’m aware X10III has a different VoLTE configuration method at firmware level, possibly a lot better one. New phone sits on shelf for 6mo already, I’ve been postponing migration because of echo cancellation, and no Camera2 API - unlucky 4.5 still seems to fail to deliver on at least those 2 issues.
Will try to work with mobile providers here for a little bit more. Maybe X10II can work.
