BUT! After short time (about 30 minutes) of testing, problems started. In that moment, I had SIM in slot 1. Photo via MMS not received (spinnig icon), but received when mobile data become disabled. Suddenly, cellular netwok settings removed. Finally, SIM is not recognized anymore in any slot. Utility to restart network subsytem does not help.
I think that VOLTE is implemented nicely, because it worked OK until something else broke. I observed similar situation (SIM not recognized after some time) also before, when I tryied SIM after initial setup (version 21, no VOLTE).
