SIM7000G not connected

I got the following module:

But the SIM isn’t registering to the network,
The SIM is “LIVE” on the dashboard,
I do have access to the module using a serial connection and I can run AT commands,
When I try: AT+COPS?
The results is 0,
Can anyone help me understand what is the problem ?

Thank you.

Found a solution by searching for available networks using:
AT+COPS=? (takes time to get response…)
And then manually setting the first one from the result.
