Update: Elisa EE home network continues to work fine, but roaming in EU, no provider allowed me VoLTE in Frankfurt Airport, nor in Lissabon. In PT I tried all available: vodafone, NOS, MEOS.
Got my Xperia 10 ii set up but it’s not registering 4G Calling (Beta) on the 3UK network
I’ve attempted to follow the tutorial in the initial post of this thread.
When doing the:-
getprop persist.vendor.somc.cust.modem0
I just get $ without numbers.
Maybe I’m missing something - SIM config ID? Where do I find it?
I’ve also gone to:-
/vendor/oem/modem-config/
and found 100’s of folders but not sure which one I’m looking for.
So now I’m in stuck city.
Any ideas on moving forward?
Thanks

Thanks for digging that out of the many posts on here.
I’ll have a look see at this in due course. 
Works like a charm on my xpera 10ii. I used the global one. Nd got the VoLTR registered after rebooting. Does Xperia 10iii work out of the box? I am using them in the U.S where thr VoLTE is mandatory.
Editing my own response. So even the 4g is registered, but the call drops instantly when I pick up or call to other people. Then the signal refreshes itself from 2.5g to 4g again, I can only make calls when the 4g is not registered. I am using T-mobile
Hi all! I smashed up my screen on my (otherwise working perfectly) 10iii and wanted to use my 10ii as a backup while I wait for the new screen to show up. But despite upgrading to 4.5.0.25, S. Ketju, I still can’t get VoLTE registration and have trouble getting on the network at all. I haven’t followed the VoLTE threads since I got my 10iii working in spring of 2022 and clearly a lot has changed since then, so I’m wondering what I’m doing wrong.
So far,
- I can’t see any VoLTE status button on the Cellular Network page (I assume this has been deprecated?)
- I downloaded NetMon, and it shows a blank screen for VoLTE, no status or anything listed at all. Modem shows powered and online everything else is an X.
I tried:
getprop persist.vendor.somc.cust.modem0
Returns nothing.
/vendor/oem/modem-config/
Does not exist.
dbus-send --system --print-reply --type=method_call --dest=org.ofono /ril_0 org.nemomobile.ofono.SimInfo.GetSubscriberIdentity
Returns:
method return time=1711070519.048808 sender=:1.9 -> destination=:1.251 serial=340 reply_serial=2 string "310260260707690"
I tried following VoLTE on the Xperia 10 II - filling in the gaps - #15 by flypig from @flypig :
mkdir -p /vendor/oem/modem-config/S21.1
echo -n "mcfg_sw/generic/euro/hutch/vlvw/uk/mcfg_sw.mbn" >> /vendor/oem/modem-config/S21.1/modem.conf
But I substituted in the files I found for TMobile USA instead. Still didn’t work.
Then I tried following VoLTE provider support - #110 by hackman238 from @hackman238 and I managed to get one text message out before it all stopped working.
I am literally sitting underneath the repeater. I can’t send or receive messages and even when the indicator on Netmon shows I have signal and am registered on the LTE network, nothing. And nothing is showing up on the MMS engine log either, other than that the bus is connected, org.ofono is owned by 1:6 and there is a modem onlinee at /ril_0.
What should I try next?
Not seeing a setting sounds like you migbt not have a license. The checkbox is definitely still there.
I purchased the OS and upgraded through the Settings/Sailfish OS updates menu. Would the license not transfer as it has always done?
These two are pretty shocking, and suggest something very wrong on that phone. Is there anything in /vendor at all? Is it even mounted? Also sounds like you’re missing at least one package if the volte switch isn’t being displayed. Did the upgrade go ok?
A while ago there were problems with the adaptation repos being lost which might cause missing volte packages. if you do ‘ssu lr’ do you see ‘adaptation0’ and ‘adaptation-common’ in the list? Does the camera work?
Good to hear you say that, @abranson, I was tearing my hair out… There could be something wrong, it’s hard to know. As far as I recall there weren’t hardware issues when I flashed it from Android 2-3 years ago (tested camera, calls, etc, pre- and post- flash)

The camera shows an image on the screen when you launch the app so it looks like it’s working – but it won’t snap a photo or record a video. Pressing the toggle for the front camera appears to reverse the image feed and freezes the app.
Maybe it’s a lemon? should I try reflashing the whole thing?
(constantly refreshing the tracking status on the new 10iii screen in the meanwhile)
Oh sorry also in /vendor there is:
adreno_symlinks-timestamp firmware_mnt
bin lib
bt_firmware lib64
build.prop
default.prop qca_cld3_symlinks-timestamp
dsp rfs
etc tftp_symlinks-timestamp
firmware ueventd.rc
firmware_folders-timestamp
Omitted from this list is oem but only because I made that directory yesterday and put relevant material in it as requested, in case something was making calls to that directory and coming up short.
Well you’re definitely missing your adaptation-common repo, so you probably have a few missing or old packages on there. Remove /var/cache/ssu/repos.ini then ssu ur should recreate it with the full set. Then do zypper ref && zypper dup and hopefully a lot of packages will install. If that oem is still missing then you’ll have to reinstall the droid-system package but I’d have to look up which one that is.
I’ll give that a shot this afternoon. Thank you!
A quick note of thanks to @abranson to say that this worked – the packages updated – and I managed to send and receive an SMS and make a phone call. But I still can’t receive calls, and VoLTE still isn’t enabled, and no toggle is showing up in Settings. Plus it keeps falling off the network, especially when someone tries to call me. So I am going to attempt a full rebuild from EMMA on up to see if this hardware is salvagable before I write it off.
A quick question as I will now be flashing directly to 4.5.0.25–do I go with the original Android image that shipped with the 10ii (something like 8 or 9, I don’t remember) or should I start afresh with Android 11?
Thanks again, community.
Did anyone have any luck with Telstra in Australia? S38.1
I tried several different modem configs and now after like the 10th reboot i am giving up. So no calls in the “4G only” regions.
Back on the N900 we had a SIP client … the days …
I’ve got running VoLTE on French provider Free mobile (S8683.1) using the generic modem configuration file, see Add modem config for French provider Free mobile by dcaliste · Pull Request #915 · sonyxperiadev/device-sony-common · GitHub
@abranson, I don’t know if it’s the right place for PR ?

Hi,
Does anyone have a working configuration for the provider O2/Telefónica Deutschland?
Getprob returns modem S77.1. There is a config for this which refers to the file mcfg_sw/generic/euro/tef_o2/vlvw/en/mcfg_sw.mbn.
However, the file does not exist. The directory “euro” does not exist, only “EU”. There is a .mbn under mcfg_sw/generic/EU/Telefonica/Commercial/DE/mcfg_sw.mbn, but VoLTE does not work completely with this file either. Registration works, as do calls at first. There is no ring-back tone, sometimes calls do not go through and the phone app crashes, sending SMS does not work.
But I’ve already been this far with the original config (which doesn’t exist).
Can anybody help?

Hey,
i also have an Xperia 10 II, and my provider is also O2 Germany, i can confirm no ring back on VoLTE, that calls are not going through, take forever to go through, also sometimes network connection is going lost when trying to call someone, and finally sms will not pass, if VoLTE activated. But i did not change any settings, so maybe that might not be helpfull for you…
I’m trying to get my 10 II to do calls on Jio in India, which, if I read the table correctly, should be possible.
The sim-card is in the second slot, so I do getprop persist.vendor.somc.cust.modem1, which yields me S523.1. If I search for jio in the firmware mount I only get one entry:
/vendor/firmware_mnt/image/modem_pr/mcfg/configs/mcfg_sw/generic/row/rel_jio/vlvw/in/mcfg_sw.mbn
So I create /vendor/oem/modem-config/S523.1/modem.conf with the following contents:
mcfg_sw/generic/row/rel_jio/vlvw/in/mcfg_sw.mbn. I’ve checked there’s no newline. I’ve turned the phone off completely. But even after waiting for quite long I’m still not getting a VoLTE registration.
Any ideas what the issue could be?
