Hologram SIM Connection

I’ve been combing through the forum looking for a solution to this:

<p style=”text-align: left;”>I am using the EnviroDIY 4g LTE Bee adaptor board and a DigiX bee board. From other posts, I learned that my RSSI light is not on, which may mean I do not have cellular service. However, I am not in an area where that should be a problem. My sim card is perfectly fine- Hologram says it is ready and I’ve even traded it out for a new one. I have a pulse antenna. The RSSI light does turn on when I begin to push the DigiX board into the LTE bee adaptor, but turns off when it is fully seated. The blue and white lights are on. Any ideas?</p>
