When applying for a bank card, is it safer to reserve a phone number for text message notification, or is it safer not to leave it?

This issue should be distinguished from reserving a mobile phone number to verify the identity of the cardholder and activate various payments on the Internet. The purpose of reserving a mobile phone number is to receive text messages about account changes. The bank discovers that there is an account change. Issues will be notified to you in a timely manner.

If a person’s account does not require a verification code to be used for online payment, there is no need to reserve a mobile phone number.

The current situation is that verifying your identity to activate online payment and reserving a mobile phone number to accept account changes are confused. This has resulted in the current situation. If you reserve a mobile phone number, you are afraid of being intercepted by the verification code, and if you do not reserve a mobile phone number, you are afraid of being intercepted by the verification code. Changes cannot be accepted.

Personal information leaks are more serious now. As long as it is your number, no matter what kind of business you handle, as long as you reserve your number, there will be information leakage. Even if you do not reserve your number, but Some of your information may also be disclosed.

In fact, I always have a sense of security, and I have multiple perspectives on everything. Now that the Internet has developed, it is much more convenient, but on the other hand, there are more information leaks. Everything is relative, and there is no absolute security. You'd better pay more attention to yourself
