BG95 International (across border) roaming and AT+COPS


We would like to allow our devices to be used on international transport.
Currently we are using AT+COPS=4,2,“PREFERRED OPERATOR”. Preferred operator is the one in the home country.

According to the AT Command Manual, AT+COPS=4 should have automatic fallback. However, this command is timing out every time. We tried anything between 3 and 10 minutes.

Is AT+COPS=4 broken?

How can we support connectivity on international transport? AT+COPS=0?

With a timeout of 12 minutes on AT+COPS=4,2,“FAR AWAY OPERATOR CODE” we see OK response after a little over 10 minutes. This is quite long? But it does seem to work. However, the AT Command manual indicates 180 seconds timeout.
