What should I do if I can't get the verification code when I change my mobile phone number in Xiaoxiang College Entrance Examination?

It may be that there are too many users applying for verification code now, which leads to the congestion of verification code sending channels, and so on.

The second situation is that the mobile phone is in arrears.

The third is that the mobile phone is in flight mode first, then turned on, and then clicked the verification code.

The mobile phone is equipped with interception software, and the verification code cannot be received. I suggest you get rid of SMS interception of application software, or try to change your mobile phone. If the mobile phone is turned off, there is no signal for the time being, and it is in arrears, or you can't receive the verification code and SMS when you stop, it is recommended that you stop the phone in arrears, usually within 24 hours after payment, basically within 24 hours. I suggest you change your mobile phone number or pick it up the next day. If the mobile phone is used abroad or can't receive the SMS verification code, I suggest you try to get it again in the future when the signal network is delayed.
