Here's my update:
Spoke with the Genius line. Even though some cars are starting to work when turning on the WiFi, others in the 2019 X5 still haven't begun working. The Genius was very honest with me about the ongoing problems and said that once the hotspot is able to be turned on that the trial will begin once it is activated.

So now for me it is just wait and see while they get each car up as they go through all of the VINs.

Outside of me trying to activate from time to time there is nothing left for me to do until AT&T allows that hotspot's SIM to start transmitting over their network.
