my airtel.chat is like this:
TIMEOUT 10
ABORT 'BUSY'
ABORT 'NOANSWER'
ABORT 'ERROR'
SAY 'StartingGPRSconnectscript\n'
""'ATZ'
SAY 'SettingAPN\n'
OK 'AT+CGDCONT=1,"IP","airtelgprs.com"'
ABORT 'NOCARRIER'
SAY 'Dialing...\n'
OK 'ATD*99***1#'
CONNECT''
My usb 3g works properly with my pc. But fails in android. I need the reason for the alarm fail.
Thanks in advance.
