Mobile phone can't receive dynamic password SMS. What happened?

There may be several reasons why the text message is not received.

1, the phone storage is full.

This situation is generally common in non-smart phones, thinking that the storage space of non-smart phones is generally limited, and many text messages are saved by default as mobile phone cards, and the storage capacity of mobile phone cards is very small, so they are generally easy to fill up. At this time, you need to delete some short messages or other things that occupy memory.

2, SMS center number settings

I can't get the text message. Maybe there is something wrong with the number setting in the SMS center. For this problem, you can set the number of SMS center correctly in the mobile phone information settings, and then confirm it to solve the problem.

3, mobile phone settings

In this case, a certain setting of the mobile phone was unexpectedly changed at a certain time, which caused the mobile phone to be unable to receive short messages. This situation may be due to recent personalization and changes in some system settings.

4. Set blacklist and information interception.

Smart phones are more convenient now, but some spam messages often harass users, and users have to set up blacklists. However, sometimes they don't pay attention. Some settings in the setting options have not been completely changed according to their own wishes, resulting in information being intercepted, so it is necessary to remove blacklist interception.
