1. Under the standby desktop-click Application-Settings-More Settings-Mobile Network-Network Operator-Search Network-Select the network operator supported by your SIM card.
2. Try to replace the SIM card.
3. Check whether the mobile phone is equipped with software such as security guards or incoming calls, uninstall it and try again.
4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.
