TEL0161 MQTT Issue

I have purchased the TEL0161 (SIM7600G) Module. I have been using the SMS functions sucessfully. I now want to use the MQTT functions. However, the first thing I try is “AT+CMQTTSTART” and I always “+CMQTTSTART: 7” followed by “ERROR”. Error 7 appears to be “network open fail”. Can anyone tell me why I am getting this error?

I believe I have solved the problem. My PDP context was not setup. Once I inserted the correct PDP Type and APN. (See “AT+CGDCONT” command.) All started working correctly. Oh, you must reset the TEL0161 Module after the changes are made. Either power down and up or use the “AT+CRESET” command.
