New Boron unable to connect to internet via cellular

Hello,
I have a brand new Boron LTE that I am setting up. The device did pair and it ran some updates. Now I am on the screen that says:

Activating Particle SIM
Connecting ot the Internet via Cellular
Starting a secure session with the particle device cloud.

Mine is stuck on Connecting to the internet via cellular and the Boron is fast blinking green.

I have exited out anr re-ran the setup, and got stuck at the same point twice now. If I log into the cloud interface on my computer, I do not see the new device listed yet.

I am in an area with good cellular coverage and have other Boron units that are working fine.

Thoughts?
