Wechat self-service unsealing prompts to send SMS verification code, which has been sent but not received. What's going on here?

It should be that your mobile phone is in arrears, or the mobile phone number is wrong.

(Reason 1)

The number of acquisitions exceeds the limit.

Solution: You can only get the verification code 20 times a day. If you have exceeded this number today, please try again tomorrow.

(reason 2)

Mobile phone service is not supported.

Solution: At present, all segments of the three major domestic mobile operators have been supported. However, mobile phone numbers in Tibet, Xinjiang, Hong Kong, Macao and Taiwan and overseas will be restricted by mobile phone service operators, so it is impossible to handle mobile telephone service. Please try to change another mobile phone number.

Note: Some number-carrying users are temporarily unable to receive short messages from third parties due to the change of data interface. Please call Netease customer service hotline for consultation.

(reason 3)

Mobile phone security software interception (for smartphone users who have installed security software)

Solution: Open the mobile phone security software first, turn off the interception function first, and then try to obtain the verification code.

(reason 4)

The SMS gateway is congested or abnormal.

Solution: When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. I suggest you try again after a while.

(reason 5)

Because mobile phones are used abroad or use overseas mobile phones.

Solution: Due to the business influence of the mobile phone service operator, the mobile phone cannot receive the verification code when it is used abroad or when it is used abroad. It is recommended to try another mobile phone.

(Reason 6)

People around you can use it normally, but they never use it, which may be the reason of the mobile phone itself. It is recommended to change the mobile phone card to someone else's mobile phone and try again.
