Technically, exactly what is going on to prevent 2 sides of the call?

Aside from the issues of being in range of the remote unit, the problem
is that a mobile phone call operates on two frequencies. This is
necessary so that it works like a regular phone call, with the party on
one side being able to interrupt and the party on the other side able to
hear the interruption even though (s)he is still talking. That's called
full-duplex operation. With regular two-way radio, you both operate on
the same frequency and only one can transmit at a time. The other party
has to wait until the first person has stopped transmitting in order to
be able to be heard by that person.

In full-duplex, each side of the conversation has to be on a different
frequency. You can't transmit and receive on the same frequency at the
same time on the same antenna -- just doesn't work. The minute you
transmitted, you'd be jamming yourself.
