No one is even putting millimeter-wave transmitters in phones right now.
But the more obvious point is that millimeter-wave 5G can only work with beamforming, and a beam that is going through your head where it is fully, entirely, fucking completely absorbed not a millimeter in, well, that's not going to yield a lot of throughput.

The 5G spec also requires certain protection when the UE (phone) Tx wave might go through tissue. But you’re correct that it doesn’t make a whole lot of sense to attempt to Tx/Rx on a beam pointed at your head since it will lead to drastically lower SNR
