We’re very happy to announce that beta VoLTE support will ship with Sailfish OS 126.96.36.199 “Vanha Rauma” on the Xperia 10 III.
As this is still an early beta, it will be disabled by default. Brave users willing to test it out are invited to enable it, with the understanding that not everything will currently work as expected.
We’ve put a huge amount of effort in to getting a working VoLTE telephony stack, but it’s impossible for us to test it in all situations and with all service providers. We’re therefore keen to receive feedback about your experiences with VoLTE if you’re willing to try it. You can participate in the VoLTE beta testing by purchasing Sailfish OS for your Xperia 10 III here.
You’ll need to have developer mode activated in order to perform the steps needed to enable it. The beta VoLTE on the Xperia 10 III can then be enabled by executing the following command at the console (be careful to get the whole command: you have to scroll horizontally to see it all):
dbus-send --system --print-reply --type=method_call --dest=org.ofono /ril_0 org.ofono.IpMultimediaSystem.SetProperty string:Registration variant:string:auto
To disable it again, use the following command:
dbus-send --system --print-reply --type=method_call --dest=org.ofono /ril_0 org.ofono.IpMultimediaSystem.SetProperty string:Registration variant:string:disabled
At any time you can check the VoLTE status of your Xperia 10 III using the following command:
dbus-send --system --print-reply --type=method_call --dest=org.ofono /ril_0 org.ofono.IpMultimediaSystem.GetProperties
The “Registered” entry indicates the status of VoLTE registration
All of these commands assume the relevant SIM is in the first slot. Replace
/ril_1 in the above commands to apply them for the second slot. If you have multiple SIMs VoLTE is only expected to work for the SIM selected for data.
Not every SIM and not every provider has VoLTE enabled and 4G/LTE is required to make use of it. If you find you’re not able to activate it, it could be for these reasons.
When VoLTE is operational, voice calls and text messages won’t interfere with 4G data transfer, but other than that you shouldn’t notice any other differences.
Beta VoLTE is only available on the Xperia 10 III while we iron out any kinks. You won’t find the required packages installed on other devices. Our hope is to roll out support for Xperia 10 II devices once further testing is complete, but that’s not the case just yet.
Please share your results with the VoLTE beta by adding them to the provider Wiki page. If you experience issues, please let us know, providing as much detail as you can, including the name of your service provider.
