Dear Lenovo users, hello!
1. Check if the SIM card is installed? Try it again.
2. It may be that the SIM card chip is stained, and you can use an eraser to wipe it. Or try to change to other telecom SIM cards, if it is normal, it means that the SIM card itself is abnormal, and you need to go to the telecom business hall to replace it.
3. It may be that there is an abnormality in the system. Let's back up the important data such as contacts, text messages, etc., and try it by restoring it to factory settings.
If the SIM card can be recognized normally, it is impossible to display the contacts inside, you can do it like this:
Go to the main menu program--- Contacts--- click the menu key--- select the "Contacts to Display" option--- select all contacts, so that you can display both body and SIM card contacts.
Or, there is an abnormality in the system. Try to back up the data and restore the factory settings under the operation. If the problem persists, it is recommended that you go to your local Lenovo authorized repair station and let the repair station engineer help you deal with it.
