I don’t think that was a feature of Dick Tracy’s wrist radio.

and also we managed to reduce power use few thousand times, and we use frequencies some 1000x higher than these old radios, up to 15000x if we insist

Mobile phones as phones—yes, maybe that’s easy. But that we don’t actually use them to TALK to people would be weird.
