Red rice mobile phone editing SMS can't come out

1. Put your mobile phone card in other mobile phones and see if you can send and receive short messages. If you can't receive the SMS, please contact the network operator to see if it's the sim card.

2. Check whether the center number is wrong. Check whether the SMS center number is normal in Settings-SMS-Advanced Settings-SMS Center Number. (Each region has its own information center number. If you are not sure, you can ask your local network operator. Mobile question 10086, Unicom question 100 10. )

3. Check whether the mobile phone has an Android optimizer, a mobile assistant or a 360. Booting is prohibited.

4. Back up the data and restore the factory settings.

5. If the above operations still can't solve the problem, it is recommended to send it to a nearby Xiaomi after-sales outlet or send it to a machine repairer online. Free maintenance during the warranty period.
