Problem description
Sim card is not being detected
Symptoms
- iPhone will show "no sim" while known working sim card is inserted
- Modem firmware is present in Settings/General/About
- IMEI shows when dialing *#06# in phone dialer
Solution
Replace SIM Reader. On iPhone XR/11/12 (Pro/Max), it is modular and can be replaced. Before assuming it’s motherboard issue, buy a new SIM reader. If this fails, your motherboard is likely defective. Another possibility is a bad baseband CPU. Try to update iOS to the newest version and check under Settings -> General -> About if any modem firmware shows up. If it's not, your baseband CPU is most likely dead and needs to be replaced.
Quick tip: Chinese iPhones use physical dual SIM. You can interchange these SIM readers between models to make dual physical SIM work on any iPhone XR/11/12 model.
