Hi all..
THIS AUTO DISCONNECTING PROBLEM IS FOR ME ALSO..I ASKED CC THEN THEY ASKED ME TO DO THIS:
Use "at" command and then type there
rcomnet=1,"ip","internet"
they assure me that this problem will be solved by this..
but i m not sure how to use this command in Run, as its not working there, so, if anyone can move forward by this or call cc and ask details about the solution.. do post here..
