Why can't the mobile phone receive SMS verification code?

The reasons why the mobile phone can't receive SMS verification code are: blacklist of mobile phone, arrears of sim card, network delay, bad cell phone signal, congestion of SMS gateway, etc.

1, mobile phone blacklist

If the mobile phone can't receive the verification code, it may be because the mobile phone has been blacklisted or blocked as spam messages. In the privacy settings, you can refuse to accept the verification code and query whether there is a verification code in the intercepted information. In addition, mobile phone security software interception is also a solution, temporarily turn off the interception function and try to get the verification code again.

2, mobile phone sim card arrears

The mobile phone cannot receive the verification code because the sim card of the mobile phone is in arrears. When the balance of the mobile phone card is insufficient, the verification code cannot be received, and it can be accepted normally after payment. This situation may be that the mobile phone has been in arrears and stopped, resulting in the inability to receive text messages. Therefore, it is the key to check whether the phone is turned off first.

3. Network delay

Network delay is one of the reasons why mobile phones can't receive verification codes. Due to network or geographical problems, the SMS verification code sent by the server may be delayed. If it still can't be solved, I suggest you consult the corresponding operators for feedback. In addition, if the mobile phone is in a place where the network signal is not good, the server will have different degrees of delay in sending the SMS verification code.

4. The cell phone signal is not good

The mobile phone can't receive the verification code, which may be because the mobile phone signal is not good. If the cell phone signal is not good, you may not receive the SMS verification code. The solution is to move to an area with better signal or try to receive the verification code at another time. If the local network signal is poor, it may also lead to the time delay of receiving the verification code.

5, SMS gateway congestion

When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. This is because when the short message gateway is congested or abnormal, the sent short message cannot reach the receiving end in time, resulting in the failure to receive the verification code. It is recommended to contact the mobile phone operator for verification or try to get the verification code after a while.
