SIM908 not responding

[jithinrajnj]

I'm working on gps project based on SIM908 module. But my SIM908 module is not responding. Network LED connected to it also not working. I don't have any circuitry to communicate serially with PC. But when i Checked the status pin the voltage on it is always less than 2.3 volt. The VDD-EXT pin is also less than 2.3 volt. I hadn't used any circuit with the power key. Does this cause any problem?please help..

Windows Xp is not necessary you can use hyper terminal in Win7. (You have to dl the application)
