Got it a week ago. Fantastic thing. My operator do now offer wifi calling. How do I set up wifi-calling on my Huawei Mate 9?
Best regards

Which carrier are you on? Which variant do you have and on which carrier? Does it support wfc on the mate 9? Not all unlocked phones support wfc on all carriers.
