Did you do something? I’ve been battling to fix that up,converted sim to esim, airplane mode, restarts, till today it was showing unknown. Voicemail was not activated and calls were on 3g signal, no VoLTE.
Same thing here, all incoming calls shows unknown. The chat or call support can’t toggle on. It is a feature I really need, Fizz, Public, ChatR have this feature by default. Going to port elsewhere.
