There’s nothing VR would give you that streaming video like FaceTime gives you. A smartphone is better because they can point it at things they couldn’t reach if they had a headset on.
Just video call and have them point with one hand while holding their phone with the other.
I’ve done it a few times. It’s not the best but vr would be far worse.
Do you think “how do I turn video back on?” would be easier in VR? You have obviously never used VR.
