It was worth a shot, but I've tried every variation possible. It's just an odd problem, to randomly stop working after two weeks.

Well got the AT commands to work, but I'm still in the same boat...

AT+CPIN?
+CME ERROR: 10

LTE has been working great for the last two weeks. Performing the final checks before deploying the field and the LTE connectivity has disappeared. The board has been mounted and no code changes were performed, now it states the "SIM_ABSENT". I haven't been able to successfully run any AT commands or i'm not sending them correctly or it's not responsive.

I've upgraded to omega2lte-v0.3.3-b253.bin and I've even tried a few different sims that were validated operational with phones and still no joy.

Can anyone give me guidance on tshooting this issue?
