Why can't the State Council travel code receive verification code?

Unable to receive verification code because:

Details are as follows:

1, it may be that the mobile phone is in arrears, and you can't receive SMS after the mobile phone is in arrears, so it is the key to check whether the mobile phone is down first.

2. It may have been intercepted by harassment. You can also view the interception information of short messages.

3. It may be that the SMS is full. This is because the short message storage capacity of mobile phones is also limited. If the user doesn't clean up the received SMS in time, resulting in too much information on the mobile phone, there will be cases where the subsequent SMS can't be received. It is recommended to delete the message and try again.

4. If the user has not turned on the phone for a long time or is in a place where the signal is not good, it will delay the arrival of the information, and generally the verification code will have a valid time. Failure to receive the message for a long time will also lead to the expiration of the message. Suggest trying somewhere else.
