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?
thanks, now it works
Xperia 10 II - SFOS 4.6.0.15 - Vodafone CZ
getprop persist.vendor.somc.cust.modem0

mkdir /vendor/oem/modem-config/S174.1

WARNING: Not possible to send smses with VoLTE enabled
To get VoLTE to work on TDC (biggest Danish carrier) on a Xperia 10 ii running SailfishOS 4.6.0.15 I did the following:
ssh defaultuser@IP-ADDR
getprop persist.vendor.somc.cust.modem0 # returns S123.1
devel-su
mkdir /vendor/oem/modem-config/S123.1
chgrp shell /vendor/oem/modem-config/S123.1
echo -n 'mcfg_sw/generic/euro/tdc/vlvw/dk/mcfg_sw.mbn' > /vendor/oem/modem-config/S123.1/modem.conf
Afterwards reboot and “deactivate” VoLTE in settings so the dot does not flicker and then click to enable it after which is should be enabled and be working.

It’s about a million years later, but my Hallon chip in Sweden now shows the phone as registered for VoLTE calling. It had previously been in eternal blinking dot mode. I hadn’t checked for a while so this could have changed some time ago.
Hi @dcaliste !
I just flashed a fresh Sailfish 5 on an Xperia 10 II.
Would you mind writing me the terminal commands i need to use now to get VoLTE working on French provider Free mobile as you did?
Thank you!

Oh thanks. So that is:
devel-sucd /vendor/oem/modem-config/mkdir S8683.1cd S8683.1echo "mcfg_sw/generic/common/default/vl/global/mcfg_sw.mbn" > modem.conf
right?
And how would be the “back steps” like if i change provider/simcard, and want now to get back to the previous state? how to “rollback” that operation lets say?
Yes, that’s it. I was not able to find where I put the steps, thanks @mkz.
There is no change to be done to revert. The change is just adding a new config file. That will be used only on Free network.

Okay nice, thanks a lot.
Bytheway so if roaming abroad with in this case a sim from Free, does the phone connects the local networks LTE with that Free config, or its needed to add local network’s (the one roaming on) config files (if someone happens to know)?
This is a good question, I don’t know the official answer of. In my experience, VoLTE works perfectly in Italy on the Iliad network (no surprise), but fails completely in Vietnam on Viettel network. I think it was not working either in the Netherland, but I can’t remember the network. As a rule of thumb, don’t count on it… 4G data on the contrary works well wherever I tried it.
I’ve travelled last year in Japan (docomo works very well) or Europa (Slovenia and Greece… I don’t remember the cariers) and VoLTE was working well.
In Croatia, I can make a short call but VoLTE seems to disconnect after few minutes…
I’m in Italy with Iliad on an xperia 10 ii and nothing I’ve tried works to get volte….however, call quality is perfectly fine already.
I don’t know. It was with a French SIM card from Free French carrier (with a 2 EUR plan + VoLTE checked in the mobile options on the Free website), and roaming in Sardinia. As far as I remember, VoLTE registered and I had some phone calls. I didn’t actively checked that data transmission was working during the calls though, but I gave a quick look on the technology indicator on top of the home screen and it was staying on 4G.
Thanks for this. Made it work on 3 (OiSTER) with a different SIM config ID.
