Love the Galaxy Note 9 but I had to return this phone because it does not have WiFi calling. It was compatible with Verizon like it advertised but apparently the model N960u1 is not compatible with WiFi calling. It was suggested that the model N960u would be compatible with WiFi calling but since I can't check it before I buy it, I won't be buying factory unlocked again. I checked the phone at the Verizon store and it does have WiFi calling and is model N960u, so maybe it is just a model problem instead of an unlocked problem. However, it was indicated by the technicians that flash firmware would have to be downloaded on unlocked phones.
