I am working with Q2686 module. My problem is that when the module is powered on , the module is not producing the voltage to drive my SIM card(sim vdd). i am using 8 pin sim card connector. I have connected with pc and checked the basic AT commands. The module is responding to the basic commands like AT , which return with OK. the sim interface in my board is same as given in the wavecom q2686 datasheet.
Please help me.
