My message must have been intercepted. What should I do?

The first scheme: card replacement, serial number 89860. The second option: do not change the card. The specific scheme is as follows: 1: Call 10086 to modify the service password. 2. Lock all SMS messages (suspected to be people around you). 3: Turn off Bluetooth (suspected Bluetooth spy). 4: Stop 1 month (only the other party can intercept your information, but inform your relatives and friends before stopping. . . . )
