How to use the housing provident fund app to extract the certification, and why can't I receive the verification code?

App certification of housing provident fund failed to receive verification code, which may be caused by the following circumstances: 1. Non-Chinese mainland mobile phone number solution: At present, only Chinese mainland mobile phone number registration is supported. Please change other mobile phones. 2. Mobile phone security software interception (for smartphone users who have installed security software) Solution: Turn on the mobile phone security software, temporarily turn off the interception function, and then try to obtain the verification code again. 3. Solution to congestion or abnormality of SMS gateway: Congestion or abnormality of SMS gateway will cause delay or loss of sent SMS. I suggest you try again later. 4. People around you can use it normally, but there is no solution: it may be the problem of the mobile phone itself. It is recommended to change the mobile phone card to someone else's mobile phone and try again. Extended data:
