Why can’t the Xiaomi 5s phone read the random password sent by China Mobile?

There are three situations:

1. Your mobile phone security software intercepts your text messages. You can view the intercepted text messages.

2. It was indeed a system problem of the mobile company at that moment that caused you to not receive the text message.

3. The most likely possibility is that your mobile phone has been "installed" with a chargeback program.

There are two modes for malicious APP to charge fees: one is to charge fees locally, writing the code directly in the program. The second is remote control, placing the deduction code in the cloud. The APP usually does not work, but it will send a request and wait for the cloud to tell it which number to send the text message to. In this way, users cannot see the virus in the APP code, nor can they 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 which SP manufacturer it is.

No matter what form of verbal deduction is required, the user's "secondary confirmation" is required. According to the policies of the Ministry of Information Industry, when users apply for subscription of monthly or subscription-based mobile information services, basic telecommunications companies should request user confirmation in advance. Without user confirmation and feedback, the subscription will be deemed to be invalid and the user shall not be charged.

If a malicious APP wants to complete the deduction on the mobile phone, it must be confirmed by the user twice. What some apps do is to intercept 10086 and 10000 text messages to the normal inbox, and automatically reply to the confirmation text message on behalf of the user, skipping the user's manual confirmation step and directly operating the user's mobile phone.
