Apple mobile phone can't receive the verification code. What happened?

The verification code is a verification instruction for many operations on the mobile phone. Only when the verification code is entered correctly can you enter the next program. However, when receiving the verification code, the mobile phone often has the problem of receiving delay or not receiving it. Why can't it receive the verification code?

There may be several reasons for not receiving the verification code:

First, the mailbox is full or the memory is full, which will lead to the mobile phone not receiving new messages. If so, delete redundant information and clear the memory of the mobile phone.

Second, if you still can't get it after deleting it, you can try changing your mobile phone or card to see if it is caused by hardware. If so, you need to find professional maintenance personnel to understand the situation.

3. Intercepted by mobile phone interception software. If "Filter iMessage Information from Unknown Senders" is turned on, you cannot receive related iMessage information sent by strangers. You can cancel by doing the following:

(1) First, click Settings on the mobile phone desktop and enter information.

(2) Then click "Unknown and filtered information"

(3) Then click the Close Filter Unknown Sender switch.

Fourth, it may be that the cell phone signal is abnormal. Check whether the cell phone signal is normal and try to test whether it can be received elsewhere.

5. Some websites or platforms have relevant restrictions. When the number of messages sent exceeds the maximum limit of one day, you will no longer be able to receive verification messages. Please try again another day.
