What should I do if the phone number verified by my realme SMS is empty?

What should I do if my realme SMS verification phone number is empty? If the mobile phone number is empty, I can't receive the SMS verification code.

It means that your mobile phone has been banned. If the empty number is displayed, it means that your number has been recycled by the system. If your software needs a verification code to log in, you need to change a new mobile phone number, and then change a mobile phone number that needs a verification code. You can log in again.
