Testing 2G (fallback) on EG915N

Hi!

I’m trying to test 2G data service (GPRS) on a EG915N. I have a simcard with 2G/3G/4G data service. I have no problem setting up a 4G data connection. In order to test the same on 2G I have tried to use:
AT+WS46=12 (GSM only)
AT+CFUN=0
AT+CFUN=1

Afterwards both AT+QNWINFO and AT+COPS? reports that the modem is using GSM. My modem is however not getting an IP address.

Is the procedure for switching to GSM correct or do I need to do anything else? I have used a similar simcard in other modems, where I only had to use AT+WS46 in order to switch back and forth between 2G and 4G.

Hi
You can use AT+QCFG=“nwscanmode”, 1 command to register only 2G network

Hi!

Does that command the exact same as AT+WS46=12 ?
