Can anyone tel me d procedure to establish a communication between a sim300 and UDP?
And When asked to define PDP context ... wat is cid and PDP type?
please help me...
Look at the FAQ's on this page **broken link removed**. The FAQ on making a GPRS connection shows a TCP connection, but UDP uses the same commands, just replace "TCP" with "UDP".

The PDP Context is a data structure that contains the subscriber session information for an active session. This includes the local IP address, IMSI, tunnel endpoints, etc. This is created when you send the "AT+CIICR" command.
You can have multiple PDP contexts and the cid is a unique number that identifies a particular PDP context. For most applications you'll only have one active session and so the cid should be '1'.
