if nokia2700 has serial port then you can try Txd and Rxd of 8051 to interface and send commands.

ok fine thanx.But i have gone through the net then i have realized that it is much better to use a gsm modem istead of cell fone since all companies follow different protocols.
Can anyone help me that which one gsm modem should i purchase and anyone can give me the the instruction set for that mossem for sending sms only.I dont want to delete etc etc.I have only to send sms from one sim to another.Kindly help me
 

There are many GSM modems in the market... china models are real cheap one's

use the at commands "AT+CMGS="mobile no."
when you receive ">" , type the messege and press "ctrl+z" to send the message

this should do the job... if you have a problem PM me

store the incoming message in a array and then display or do whatever you need.....
