A notice will be shown during registration or when updating phone number to inform users about the possibility of phone number blacklisting.
If you encounter a situation where your phone number is blacklisted, the only solution in this case is to register with a different phone number. This ensures that you can complete the update or registration process successfully.
It's important to note that the Admin cannot intervene in situations where a phone number is blacklisted. While Admin may assist with other inquiries or technical issues, they are unable to address this specific situation due to system limitations.
