Cool God f2 suddenly didn't receive a text message these two days. What happened?

1. It may be caused by network delay. Observe whether there is this phenomenon in the surrounding mobile phones.

2. The mobile phone is full, which makes it impossible to accept SMS. It is suggested to delete some short messages and multimedia messages on your mobile phone.

See if you can send a message. If the short message cannot be sent, check whether the number of the short message center is correct.

4. Mobile phone settings. It is recommended to back up important data and restore factory settings.

5. Set blacklist or information interception;

6. Replace the mobile phone card and test whether the mobile phone problem is a card problem. If it is a mobile phone problem, it is recommended to send the mobile phone to the after-sales outlets for specific testing.
