What's the matter with iphone suddenly failing to receive text messages?

The mobile phone suddenly can't receive the short message, which may be due to the poor signal and the arrears of the mobile phone.

Question 1: A question for no reason.

In this case, I was fine a few days ago, but suddenly I didn't receive a text message and didn't do anything unusual with my mobile phone. In this case, it's usually not that my mobile phone is broken, but that there is a small problem on the server side of the operator, network delay and other reasons, so I called your mobile phone network operation service station, such as mobile phone 10086, telecom 1000 and Unicom 65438.

Question 3: The storage space of the mobile phone is full.

This situation is very common in non-smart phones. People think that the storage of non-smart phones is usually limited. By default, many short messages are stored in calling cards, which have a small storage capacity and are usually easy to fill. At this point, you need to delete some short messages or other contents that occupy memory.

Question 4: SMS center number setting.

I can't get the message. There may be a problem with the number setting in the SMS center. For this problem, you can set the SMS center number correctly in the mobile phone information settings, and then confirm to solve the problem.
