With Online AT Command Tester tool, you can test Simcom TCP/IP feature.

You can also send commands to set up TCP/IP connection in the ‘Script Mode’ tab of the AT Command Tester,


//Check the registration status
AT+CREG?

//Check attach status
AT+CGACT?

//Attach to the network
AT+CGATT=1

//Wait for Attach
WAIT=7

//Start task ans set the APN. Check your carrier APN
AT+CSTT="bluevia.movistar.es"

//Bring up the wireless connection
AT+CIICR

//Wait for bringup
WAIT=6

//Get the local IP address
AT+CIFSR

//Start a TCP connection to remote address. Port 80 is TCP.
