Meizu mobile phone can't receive short messages, only send them. What should I do?

How to deal with the problem that mobile phones can't send and receive short messages;

① Check whether the mobile phone network is abnormal.

(2) Check the SMS blacklist to see if there is any SMS blocked. At the same time, you can also consult the operator to see if the card is abnormal, get the number of the SMS center, and open the SMS-Settings-SMS Center Reset Test.

③ If you use security housekeeper software such as 360 or turn on ROOT authority, it is recommended to try to uninstall all mobile phone management software and turn off root authority, and then restart the machine to see if there is any improvement.

④ You can try to change an original small card for testing.
