Why can't my mobile phone receive the random password information sent by mobile communication?

1, your mobile phone security software intercepted your message. You can check the intercepted message.

2. It was really the system problem of the mobile company at that time that caused you not to receive the SMS.

3. The biggest possibility is that your mobile phone has been "installed" with a fee deduction program.

There are two modes of malicious APP deduction: one is local deduction, and the code is written directly in the program. The second is remote control, which puts the deduction code in the cloud. The application usually doesn't work, but it sends a request and waits for the cloud to tell it which number to send a text message to. In this way, users can't see the virus in the code of the APP, and they can't see the SMS number. Through remote control, the virus author can change the number at any time, which is controllable at any time, and it is difficult to find out which SP manufacturer it is.

No matter what form of withholding fee, users need to "confirm twice". According to the policy of the Ministry of Information Industry, when users apply to subscribe to mobile information services on a monthly basis, basic telecommunications enterprises should confirm with users in advance. If the user fails to confirm the feedback, the subscription will be deemed invalid and no charge will be charged to the user.

A malicious APP wants to complete the deduction on the mobile phone, and it must be confirmed by the user twice. Some apps intercept 10086 and 10000 messages to the normal inbox, automatically reply to the confirmation message on behalf of the user, skip the manual confirmation of the user, and directly operate the user's mobile phone.
