Can I change my real-name registration system mobile phone card in the Telecom app? Is it safe?

You can change the real-name registration system mobile phone card in the Telecom app, which is safe. The reasons are authentication, real-name management and security technology.

1. Authentication: Before the real-name registration system replaces the mobile phone card, you need to authenticate yourself, such as entering personal information such as ID number and name. This method can effectively prevent others from using your identity to change their mobile phone cards, and ensure that personal information will not be leaked.

2. Real-name system management: According to relevant national laws and regulations, China Telecom requires users to carry out real-name registration system authentication, that is, to authenticate users' real identity information. This management method can effectively protect the personal information security of users.

3. Security technology: Telecom APP adopts various security technologies such as encrypted transmission and data isolation to ensure that user information will not be leaked and tampered with during transmission and storage.
