Unable to get SMS. What happened to the replay attack?

The reasons why we can't get the short message are the wrong number of the information center, the arrears of the number, the abnormal reception and forwarding of the network base station and the failure of the mobile phone. Solution:

1. Correct the information center number. First, check whether the message center number set by SMS-SMS Settings-Message Center Number in the mobile phone is correct (compare it with similar local cards or consult the operator to confirm the message center number).

2. Information centers are stored in mobile phone cards. You can change your mobile phone card and restore the factory settings (Settings-More Systems-Restore the factory settings, please do not completely check Clear) to eliminate the contrast. Determine whether it is a mobile phone card problem or a mobile phone problem.

3. Change the observation and comparison in different time periods.

4. Consult the mobile phone card to exclude the phone bill balance.

5. If the above methods fail to solve the problem, please take the purchase invoice, warranty card and mobile phone to the nearest brand mobile phone customer service center for testing and handling.
