We will do it step by step...
first search to forum for lcd interfacing, and u will get code on 8052.com - The Online 8051/8052 Microcontroller Resource - 8052.com for LCD interfacing...

Later we will deal with GSM interfacing..

Just try to do man one by one.If you have doubts then do post it here & we will surely help you.

}

the gsm modem is recieving the messages only one at a time and displaying if we send another the previous message is not marking as unread please do the need full.
