The mobile phone has never received the verification code. What happened?

If your mobile phone has been unable to receive the verification code, there may be the following reasons:

Signal problem: If your mobile phone is in an area with weak or no signal, it may not be able to receive verification code messages normally. Try moving to a place with a good signal, or try again after the signal is restored.

Mobile phone settings: Check the settings of the mobile phone to ensure that there is no setting to disable or prevent SMS notification. Sometimes, some applications or settings may prevent text messages from arriving.

Wrong setting of SMS center number: SMS center number is the key setting for mobile phone to send and receive SMS. If the number of the SMS center is set incorrectly, you may not be able to receive SMS normally. You can contact your mobile phone operator to get the correct SMS center number and make adjustments in your mobile phone settings.

Spam message filtering: Some mobile phones or communication applications may automatically filter spam messages and move them to the spam message folder. Check whether the mobile phone has turned on the spam filtering function, and confirm that the verification code message has not been misjudged as spam message.

Operator problems: Sometimes, the delay or loss of SMS transmission may be caused by the operator's network problems. If you often encounter the problem of not receiving the verification code, it is recommended to contact the mobile phone operator for consultation and seek their support.

Please note that the above are some suggestions, and the specific solutions may vary according to individual circumstances. For the problem that you can't receive the verification code continuously, you'd better contact the customer service department of the mobile phone operator or mobile phone manufacturer to get customized help for your specific situation.
