What happens to my electronic signature if I transfer my mobile number to another person?

Your signature approval must always consist of two factors, e.g., possession and knowledge. For example, you possess a mobile number, and you know your password when using, for example, the password and SMS code method (PWD/OTP).

When you transfer your mobile number to another person, you lose possession of that particular mobile number. Thus, your registered digital identity linked to your electronic signature cannot be triggered.

Therefore, you need to register again with a new mobile number.
