Check the text messages received by the mobile phone.

First, the number of the SMS center is wrong.

Because different regions and different carrier networks in China, the corresponding SMS center numbers are also different. In addition, for users, it is not only tedious to find the number of SMS center on the Internet, but also the version and year of many materials will cause inaccurate information. You can go to the business halls of local operators to find out, or call China Mobile (10086), China Unicom (100 10) and Telecom (10000).

Second, the cell phone signal is poor.

If you are in an occasion where the signal is unstable, the network is temporarily lost or affected by other aspects, the short message may be temporarily unavailable or delayed. In order to solve this problem, you need to go to a place with good signal to receive short messages.

The third is the problem of the mobile phone itself

This phenomenon is unlikely to happen. Generally speaking, users will choose to try out the information function when buying a mobile phone, and may not use the information function unless there is obvious fall or bump in the subsequent process. For example, the phenomenon that some short messages cannot be received should account for a small part of the relationship with the mobile phone itself, and the other part should have a greater relationship with the operator's network. Users don't have to worry about this phenomenon, because similar delays don't happen often, so they need to wait patiently.

Fourth, the blacklist function of mobile phones.

This will prevent SMS from receiving messages containing blacklisted numbers. At this time, it is necessary to turn off the blacklist function of the mobile phone and then restart the mobile phone to solve the problem.

Five, mobile phone arrears

Now that the mobile phone is running out of money, the average operator will send a text message to remind you unless you ignore it.
