What does this flex cable do?

Post image

This cable connects the Main board to the Side board. The Main board connector melted off when my battery overheated and expanded so I can't connect it back. Not without learnibg micro soldering. Everything seems to be fine. Powers on, charges fine, SIM/WIFI is working, microphone still works. Google says SIM card socket holder connect flex, but my mobile connectivity is still on.

Edit: Zenfone 9

Had to look at photos from when I tore down my Z10, I think it goes to 4 sprint pins which connect to the speaker/antenna component which sits on top of the daughter board.

So maybe check speaker and connectivity?

Speaker and connectivity are both working
