Why can't Apple receive the SMS verification code?

There are many reasons why Apple's mobile phone can't receive information, as follows:

1, there is a problem for no reason: this situation is generally not a broken mobile phone, but a problem on the operator's server, network delay and so on. So call the mobile phone network operation service desk, such as mobile 10086, telecom 10000, Unicom100/0, etc. , and transferred to the manual service. Explain the situation.

2, mobile phone arrears: this is the most basic problem. Nowadays, mobile phones are generally used to evaluate credit rating. If the credit rating is high, the amount you can owe is even greater, depending on whether the payment is timely or not. Now that you are in arrears, you will not directly cut off the functions of mobile phones and short messages. So, when you can't receive the text message, think about whether the operator sent a text message to urge you to pay the phone bill and didn't pay it.

3. The mobile phone is full: This situation is generally more common. Many short messages are saved in the mobile phone card by default, so they are generally easy to fill up. At this time, you need to delete some short messages or other things that occupy memory.

4. Number setting of SMS center: You can't receive SMS, or there may be a problem with the number setting of 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.

5. Poor signal in the wrong place: In tunnels, tunnels, deep mountains or sparsely populated places, the signal is generally poor, and mobile phones can't receive short messages. Or other places, but the instrument with signal shielding shields the cell phone signal, so it is temporarily unable to receive information. Just change your location and go to a place with good signal, and you will naturally receive the information you didn't receive.

6. Mobile phone settings: In this case, a certain setting of the mobile phone was unexpectedly changed at a certain time, resulting in the inability of the mobile phone to receive short messages. This situation may be that some system settings have been changed recently, so go to the phone settings and click "Backup Reset".

7. Mobile phone hardware/system problems: System problems can be solved by reinstalling the system or factory setting. Hardware problems have to be repaired after sale.
