Hello Vy_Nghia, thanks for your question If the network connection is abnormal, you can try the following command to determine whether the network is registered: AT+CFUN? //check cfun status AT+CPIN? //check SIM Card status AT+CGREG? //Check the registration status of the PS domain AT+CREG? //Check the registration status of the CS domain AT+QENG=“servingcell” //Check if the module resides on the network AT+QMBNCFG=“List” //Check if MBN activation does not match AT+CGDCONT? //Check if the APN configuration is correct AT+QICSGP=1 //Check if the username and password are configured correctly You can also restart after power off and retest the network. If the problem still exists, you can catch the problem log email to support@quectel.com, we will analyze your log, thank you.

Hello hanskr, thanks for your reply
This shows that your network connection is normal, and the AT+QICSGP command requires configuration parameters. The specific configuration process can be seen in section 2.1.1 of the attached document. Thank you. Quectel_LTE_Standard_TCP(IP)_Application_Note_V1.1.pdf (445.1 KB)
