I tried writing script that send SMS that contains GPS coordinates in it. The script works fine when I test with USB to TTL Programmer attached with the A9G Board. But when I remove that and try to power A9G board with battery or direct USB it doesn't work at all. It say's SIM not inserted

can anyone tell me the exact problem ?

Have you checked the power drawn while establishing a GSM connection?
