SIM card not detected

[AddieDirects]

Long time listener, first time caller here.........

So I got a SIM for my PP Ub Ports edition. I plopped it into my phone and it still says "SIM not detected" in the Cellular settings menu. Being that this is my first Linux smart phone (though I'm not new to Linux. My daily driver laptop runs Fedora) I'm stumped. I've tried searching the forums, and using the Google machine, but all of the solutions (ex: this topic) did not seem to do anything to get my SIM to recognize.

Things I know....

• It's a brand new SIM from a prepaid company in the US.
  
• As far as I know the SIM does NOT have a PIN on it.
  
• They give you SIMs for both AT&T and VZ and BOTH have the same issue....the "Cellular" option shows up on the settings, but when you go in there to get the IMEI to register the SIM, it shows up as "No Sim"
  

Anyway....................HALP! I'd love to test some of the phone capabilities of the phone. So far I'm fairly impressed for what is essentially development hardware and alpha software. It seems to be WAY better and more polished now than the many year...oh wait...months ago that I played with a Brave Heart phone at a friend's place in the pre-pandemic days of winter.
