Available operator List via AT+COPS=? | Telit Cinterion IoT Developer Community

Hi,

I'm trying to use AT+COPS=? to get a list of all the available network operators to allow a user to manually choose one.

This seems to work fine on a EHS5-E mode. On the other hander, it fails when using a PH8-p.

In this case, I'm constantly getting an "+CME ERROR: operation not allowed" response after a few seconds waiting.

The SIM in use is the same one.

Why would that be? The documentation says it should work.

NOTE: When using the "AT+COPS=0,2"(write command for automatic network selection, it works just fine.
So does the "AT+COPS?" read command
