Fail to Registration a network for M66

Hello Experts,
I am trying to configure M66 module for HTTP connection. When tried Qnavigator setup I am getting error of fail to register on network. Kindly help me how to register network ? how to setup basic HTTP communication?.


Hi,I observe that you use AT+CREG? The reply is “0,0”, which means that the automatic network injection of the module fails. You may use AT+CSQ to check the signal value of the antenna. I suspect that there may be something wrong with your antenna and radio frequency
