On my Mi 10 global i cant use VoLTE with my o2-card (Germany). The Option is visible and activated, but no symbol is shown in the Statusbar. All incoming calls are "unknown Number". Any Solution?

Dear Mi Fan,
    Please, clear data for Phone & Dialer app and in Contacts settings, click the option 'Rebuild Index Data" & let it finish. Also, try merging the duplicate contacts, as the same number, saved with two different names in Contacts  is displayed as a number only. Hope it'll fix your issue.

i think there is an IMS Problem. i Made a Screenshot from the IMS-Status in *#*#info#*#*
one is with "VoLTE active" one without.

I have the same phone (Mi 10), same provider (o2 Germany) and unfortunately the same issue. Is there a fix to this?

No issues with my Mi 9 on o2/1&1. Both VoLTE and VoWIFI works. Good luck. I used to have a Mi MIX 2S and had VoLTE and LTE connectivity issues and Xiaomi never fixed it.
