Test SIM800L

Is there a way to test a SIM800L board without using a SIM card? Or, without network? I have no network where I am currently, but I want to test it now that I got it soldered in place.

The light comes on and powers up properly right now, but signaling not connected to network.

Before I soldered it into the final project, I was able to take the board up to a high point, and the light blinked, signaling it was connected to the network.

Maybe there is a simple command that doesn't require the card? I looked online, but no one seems to need to do this.


Hello? Can someone please help?

I found some test code finally. It is even simpler than I thought it would be.
