I have an unlocked Galaxy Note 10+ 512GB that was purchased through Samsung and I have service with AT&T. Why do I not have the ability to use wifi calling or video chat. I don't even have the option to turn wifi calling on. Is there any update to the firmware I can do or any other solution.
This is a carrier feature and AT&T has elected not to provide that to unlocked devices at this time.
T-Mobile provides unlocked phones with WiFi calling but ATT doesn't. So normally if you rely on some of the carrier's features, you need to go with their branded models.
OR you could flash your devices with another firmware, but most users wouldn't want to mess with it.
