Peplink BR1 Max - No Sim card Detected

Having an issue, where peplink BR1 Max will not detect the SIM cards inserted in Slot A and Slot B.
Tried with ATT on Slot A and Verizon on Slot B.

Switched the SIMs around and configurations, and still no SIM detected. It only detects the E-SIM port included.

Tried reseting and rebooting several times.

Can someone suggest a way to get the BR1 to recognize the SIMs again?

Thank you,

Rafael G.
