Just installed GOS on a Pixel 8 I bought on Backmarket. Setup went fine, but when I put my SIM card in, the mobile network is set to Emergency calls only, the Mobile network state is Disconnected, and Service State is Out of Service. Manually setting APN didn't work. Resetting network settings didn't work either. The correct phone number and carrier (Metro by T-Mobile) is being displayed when I go to About phone, so it must be reading the SIM correctly, right? Checked the IMEI number and the phone isn't blacklisted or anything. Anybody else get this problem or have any suggestions?
