Hello,
I have noticed that there is an unpopulated footprint for a SIM card holder on the back of the EC200A-EU miniPCIe module. I have soldered a sim card holder matching the footprint, but when I insert a SIM card I keep getting +CME ERROR: 10, which as I understand indicates that it does not see the card. Are there any other parts that need to be populated for this interface to work or am I just doing something wrong? I have not tried it with another card as of now. Thanks for the help in advance!
