Beta VoLTE on the Xperia 10 III, disabled by default

Yes, there may be ways, but it depends on many factors including your provider’s configuration and the device you’re using.

The first thing is to check the VoLTE provider support page and see whether your provider is listed.

Some have additional instructions linked from there and in particular, many require you to follow the instructions on the filling in the gaps page.

I would say those are the two best places to check first.
