It does.

How do they know when you use it? It is a one-way system!!!

It happens in the receiver.

You call to activate it and your receiver unlock code it included in
the downlink stream, correct?

Yes.

Why would XM delete your unlock code from the downlink stream if you
are paying your subscription?

They don't. The activation is normally a one-time thing.
