Sim Card Not Inserted problems... | Telit Cinterion IoT Developer Community

Hi all,

I have a custom board with an EHS6. We followed the hardware integration description but when we insert our sim card, the module does not seem to detect it. AT+CPIN? yields "+CME ERROR: Sim Card Not Inserted".

I confirm that the CCIO (Sim card card detect) goes high to 1.8V. However, CCVCC, the Sim card VCC line, is always stuck at 0V.

Is there any configuration I need to do in AT^SCFG or something? Hopefully I'm just missing something obvious.
