We are having issues with RC7620-1 modem connection to the network in specific places like Australia while no issue in other places. The modem starts OK and we get the CREG: 0 and CREG: 2 but nothing else after that. It just hangs there until our 5 minute timeout. I have tried to set RAT switching …

I think APN is needed for LTE network. yes, you can try Release 9 BTW, you need to isolate if this is SIM card issue.

Yes, setting APN before waiting for connection works. Thanks for that information.
