Where do I enter my Cell number to have my phone ring?

Upon completion of setting up my new Zoom Phone number online and on my mobile app- it appears I can make calls and texts no problem. My inbound calls, however, do not ring to my cell phone. Call forwarding is off, my cell phone volume is loud, and I have the correct time zone.

Did I miss where I'm supposed to enter in my actual cell phone somewhere in set up? Why won't it ring to my phone so I know I'm getting a call? I have 1 Zoom Phone number license for the $15/mo.
