Can you try AT+CIPSHUT before issuing AT+CIPSTART

and better give command with the IP of the website which you want to access as follows
AT+CIPSTART="TCP","74.125.224.72","8080"

 

[ud23]

AT+CIPSTART="tcp","raviyp.in","80"
OK

you have to send command with '/r,/n'. Don't send OK with the command.

this is error codes you have pin setting in your sim.

I think there are several wrong assumptions in the previous post.

- Obviously ashueda is showing the AT command responses, not sending "OK".
- The OK response indicates that the commands are correctly formatted
- I believe that the GPRS and IP related commands won't be answered O.K. without network registration, in so far it's unlikely a SIM PIN error
- I don't think that ERROR: 6 is a CME ERROR
