AT Command Syntax to send SMS via Bluetooth connected to Pic

I am using a bluetooth module connected to pic to talk to a LG cellphone to send SMS messages to another cellphone. My cellphone allows me to send the SMS message in text mode to an email address by typing in that address instead of the phone number. I need to do this by using AT command and have tried several syntax formats without any luck. I have searched the web for a couple days and have not had any luck finding the information I need. Can anyone help with the correct command syntax?
