How to delete the charging software in the mobile phone?

It is distributed in many places of each functional module, which makes people hard to prevent. Now let's talk about several ways to solve the trap of shielding SMS charges. 1. After purchasing a new mobile phone, once the SIM card and the memory card are inserted into the mobile phone, multiple function folders will be automatically created in the card, including the "dsm" folder. The sending address of SMS messages will be hidden in the folder named "dsm", and the file names are update.ini and dsm.ini respectively. Connect the mobile phone to the computer and open these two files with notepad text documents. Never delete these two files (they will be re-created after deletion). After opening, delete all the short message addresses and save them. Ok, when you get to the most critical place, you should change the file attribute to "read-only" after saving, and remove the "archive" check. From then on, it was all over. Press the trap function on the mobile phone again, and "initialization failed" will appear without sending SMS. This principle is to make the system think that these two address files still exist and will not be re-established. As for changing file attributes, mobile phones are not allowed to write new SMS addresses. This kind of mobile phone manufacturer with tariff trap will not add some back doors, and their mobile phones can automatically update or send some information with a signal. Therefore, for the sake of safety, the majority of shanzhai users should not use this kind of mobile phone with tariff trap for online transactions. Second, after the mobile phone is connected to the computer, it will automatically find two "mobile disks". One memory card has a large capacity, and the other has a small capacity. Only a few hundred K is the storage space that comes with the mobile phone. The "dsm" folder is on a small removable disk, and the "dsm" folder on the memory card is empty. There is an easy way to find this "dsm" folder. The mobile phone is not connected to the computer. After you go in, you will have a mobile phone and a memory card by using the file manager that comes with the mobile phone. Select the phone and open the dsm folder. There are two files in the folder: update.ini and dsm.ini 1. Turn off GPRS function. It is turned on by default, and there is no charge when it is not used at ordinary times, but once it is used, and there is no monthly subscription or the traffic is exceeded, the cost is very large. For example, the streaming TV function, online cinema function, online music function and ringtone video download function of some cottage machines will generate huge traffic costs. After closing, you will not be able to use MMS and other functions, and you will not be able to access the Internet through GPRS. 2. Turn off the SP information on demand function. By default, it is enabled. Generally speaking, this function means that users send short messages to a certain number of SP service providers to request some information, and SP service providers charge users related service fees, ranging from a monthly subscription to a few cents to several yuan. This is also the legendary "fee-sucking function". After turning off this function, there will be no way to send information to the SP operator's number, but it will not affect the reception of information and the transmission of information between users' mobile phones. When calling customer service, be sure to explain to the customer service staff that "GPRS function and SP information on demand function are cancelled because there is charging function in the mobile phone". (Not less than one word): Mobile users demand to shut down: Monternet's SP on-demand platform service Unicom users demand to shut down: "Unicom is in the letter" SP SMS service Note: According to the relevant regulations of People's Republic of China (PRC) and the Ministry of Industry and Information Technology, it is illegal for operators to send SMS without prompting the button. Third, modify the internal program of the mobile phone. This can only be achieved by programming instrument software.
