Hi @Alaa
Please ensure that the module antenna is connected properly.

Hi @lyman-Q
The antenna is connected and I can access gsm only, but when I tried to access LTE by the command “AT+QCFG=“nwscanmode”,3,1”, this error occurs, and note that I have LTE connection on my phone in the same place. How I can debug this issue.
Thanks in advance.

Hi @Alaa
May I ask what error code was reported?

Hi @lyman-Q,
I mean the modem stocking in the searching state and cannot connect to LTE network, just connected to GSM
