I currently used the sim300 kit with my atmega128 uniboard v1.1 . I burned the Chat program on the MCU and I connected the SIM 300 module with the UART0 of the MCU and connected the %V and GND pins of the module from the MCU 5v and grnd supplies .Also I tried powering it externally using a 7V battery.However the power led is the only one that glows with no network detection despite the fact that the simcard has been inserted.Please help
