EC20-CE disable LTE(4G)

Hello everyone,

I am getting ERROR

when I send "AT+QCFG=“nwscanmode”,1,1 // to enable GSM only

NOTE: The module doesn’t have a USB port, I am sending the command using UART.

Are there any other steps before sending the nwscanmode?

Thanks in advance

what is the ERROR number?
Please use AT+QCFG=“nwscanmode” to check the return value.

Response is ERROR
Not geeting any ERROR number


what is the return value of AT+QCFG=“nwscanmode” command?

while sending this command using UART Getting return value is 0(Zero).

Please input ATV1 first, and then input other AT commands.

After inputting ATV1, correct response getting for other AT commands.
when I input AT+QCFG=“nwscanmode” the response is ERROR.
