So my Nokia 5.1 stopped reading the SIM card. For some months it had already only read the SD card intermittently, but then the SIM card stopped working, too.
I tried restarting and resetting network settings; no luck. I bought a new SIM tray from a reputable shop, put it in, and tried putting in the SIM; no luck. I tried experimentally putting my mother’s SIM card in, to see if the issue was my SIM card itself; no luck, it wouldn’t read that there was a SIM card inserted at all, and I tried it with both the old and new SIM trays.
I’m wondering if it’s something in the phone’s hardware itself, rather than the tray. All I know is that it’s unuseable for things like texts and PayPal, signing in for anything with two-factor authentication, etc., because they also all rely on texts. Help?
