SL8082 QSC6270 CREG=0,2 error

Hi awneil,
Thanks for the reply,
Problem was with my antenna connections. solved it.

now i am trying to connect my module to the GPRS network.
What is the sequence of Configuring or setting up the module for connection.
i am referring the supported commands & 3GPP 27007-630 specifications document.
can you suggest more document for this?

thanks
