/* Use AT+QIOPEN=1,0,“TCP”,“192.168.7.48”,1880,0,1 to connect to a TCP server (IP address: 192.168.7.48:1880). */

Dear Sir,
Thanks for your inquiry in Quectel forum.
About your issue, please double check whether your PC IP can connect to module IP. As you know that your PC IP 192.168.7.48 is in the local area network, not wide area network. Normally, it can not connect module and your IP directly, you need to map your PC IP to public network. You can try to PING module IP in your PC to confirm whether the network is connect or not. Thanks!

Dear Sir,
Yes, you can use AT+QIACT? to get module IP. If you cannot ping module successful, which means that the module and your PC are not in the same local are network, you can not connect them directly. Thanks!
