thanks for all....

When you get sms, in your code discard all messages till you get 1st character as '+' which will be followed by 12 digit phone number. e.g.+91xxxxxxxxxx.

So you read the sender phone number.
Next you can read the message content, by storing it in array or directly read as a string

sir how can we check for start of msg using the same technique i.e what is the last character received to ucontroller before the message body.
and also the delete all command is not working on my gsm module please advice me
