Nothing is beamed directly to your phone, it’s a broadcast, so waves n stuff.

I think they meant the phone is beaming the horrific news to their face which is inches away, not that the horrific news is beamed directly to their phone

But underneath it's just unicast to your phone, no?

But anyway, beamed directly it may be, it's called beamforming.

In the world of 5G, this is the act of focusing a wireless signal in a specific direction. Compared to simply sending a signal across a wide area, beamforming requires more sophisticated antenna technology.
[...] Beamforming technology, on the other hand, sends a precise and concentrated signal right to your smartphone. It is more deliberate and intentional with its delivery method.
