Pixel 4a 5g NO NETWORK WONT DETECT SIM

[GeeAyeZee]

I purchased a pixel 4a 5g yesterday secondhand and it turns on and everything works except for the fact that it won't detect the SIM and shows no network in the top right of the screen. It won't allow me to use mobile data at all. Somebody hopefully has repaired this issue before and can advise me what to do?? Thanks

Try doing a factory reset to the phone - maybe the first owner had the phone configured to use an eSIM so it may ignore physical SIM cards.

I've tried the factory reset. Also flashed a couple different firmwares that I downloaded from Google

Just tried flashing Lineage 18 and after a successful flash I still have no sim detected and no data. The guy I bought it off said that his kids may have dropped it in some water but If it was water damage I don't think it would turn on at all. I'm at wits end with the thing.
