Hi!!!!!!
Thanx 4 ur reply.........
actualy i am working on a project in which i have to send the location of the tower through which the mobile is communicating at that time through an SMS.........so, how can i do it?????

read your AT manual

hi,
Please use the following commands to get cell ID first on hyper terminal . then try on Micro controller.
AT+CMGF=1
AT+CNMI=2,1,2,0,0
AT+CSCB=0,"50","1"
it will keep on giving you cell site name after every 1 minutes.
Please try this and let us know the result.
