Initit the HTTP service,
AT+HTTPINIT
OK

Try to set the HTTP session.
AT+HTTPPARA=”CID”,1
OK

Set the HTTP URL
AT+HTTPPARA=”URL”,”

Now, start the session
AT+HTTPACTION=0
OK

Please be sure that the PDP context is set properly.
Still doesn't work? Try a firmware upgrade for your model.
Btw, will be great to have your setup code and firmware/revision number.
