Hello!  
My name is Adrian Garcia, I’m new using wavecom products. I’m now using a DevKit for the Q2687. I’m from Argentina, so I apologies if my english isn’t very good.

Problem 1)  
When I start the Expresso and try to connect to the kit, I succesfully connect to the board, but I cant detect the simcard. So measuring the SIM\_VCC, I realized that its 0V. So, maybe that’s the problem… I have a configuration issue?? how do I solve it?

Problem 2)  
Once established the connection with the board, using AT Commands, I query for the signal status (AT+CSQ). But I only received an +CME ERROR: 3.

Maybe, problem 2 is related to problem 1…

Thanks in advance!
