Why can't I get the verification code when I receive and fill in the information for the birth permit?

1. The interception software is installed in the mobile phone, and the verification code cannot be received. I suggest you remove the SMS interception of the application software, or try to replace the mobile phone. 2. The mobile phone is turned off, there is no signal for the time being, the payment is overdue, or the verification code and SMS can't be received. It is recommended that you stop the phone due to arrears, and it will generally be restored within 24 hours after payment, basically within 24 hours. It is recommended that you change your mobile phone number or get it again the next day. 3. If the mobile phone is used abroad or you can't receive the SMS verification code, I suggest you try to get it again later if the signal network is delayed. 4. The SMS storage is full, and the SMS verification code cannot be received. It is suggested that you try to switch the phone on and off.
