    hi i have a problem with my sim900 module it is not providing status light glowing continuously and my net light blinking little faster which indicates that sim900 doesn't recognise the presence of simcard...The voltage at pin 30 is 0.01.I'm sure that my sim900 is working fine but i don't know why the voltage is zero at pin 30....please share your suggestion
