Available operator List via AT+COPS=?

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
