welp, I got the piece of broken SIM tray out of my old phone, but it still won't read my SIM, I guess it was a good call to replace the device because if I get this fixed it'll take quite a while (and probably not be worth it, considering the price of a used LG G6)
I guess I could still do *something* with this phone, especially if I get the broken USB port fixed, it's still a fairly powerful little device
