Can the deleted SMS content be restored? Can you find it without a password?

If your mobile phone has a recycle bin, you can restore it, or if you had a backup on your computer or memory card before, you can restore it by restoring it. As for the data recovered on the first floor, it is basically impossible to recover without backup, or you can try to recover the hard disk like a computer expert, but the cost may be higher. As for online search, I have been in the mobile phone industry for five years and think it is not credible. First of all, you think that China Mobile or China Unicom should keep confidential data for customers, and their records also record who you sent it to and when. As for finding the content, it is impossible, but the authority is definitely high. Therefore, it is basically impossible. Generally, there are two methods: one is that your mobile phone will not be formatted on the premise of data recovery, and the other is to query the database. There is a professional inquiry network, which can check the call records and short messages according to the answering time and evaluation level. Netizens answered (***46 answers). Recently, a mobile phone information recovery software popular on the second floor "subverts" the confidentiality of mobile phones. 90% of mobile phone information can be easily recovered. The recovery software can be downloaded online for free. Through Mr. Zhang's introduction, the reporter found a software called "Rereading Mobile Phone Information" on the Internet. According to the prompt of the software, 1344 messages, 6 pictures and 109 phone numbers were successfully recovered in only 5 minutes. Then the reporter contacted a company specializing in this service. The company's technicians assured the reporter that they were fully capable of recovering data for the reporter's mobile phone at the cost of paying 60 yuan's service fee. At the same time, they promised that they would not charge any fees if they could not resume their success. They only need to pay for deleting information and fix it at any time. 16 at 4 o'clock in the afternoon, the reporter came to a computer company in Keji Street, Chengguan District, Lanzhou City with his mobile phone. After paying 60 yuan's service fee, a man wearing a floral sweater connected the reporter's mobile phone to the computer with a data cable. When the mobile phone was started by a computer program, the man opened a page of recovery software. The man who is helping reporters recover mobile phone data told reporters that this recovery software is very powerful. It can not only restore all kinds of data that have been deleted in the mobile phone, but also customize the information content received in various mobile phones. The man skillfully found the "H" disk representing the reporter's mobile phone and began to fully recover. With the program running, the percentage on the search interface increased rapidly, and the search ended in less than 3 minutes. The results show that there are 157 1 messages and 158 phone numbers in the whistleblower's mobile phone. There are six pictures. 227 more text messages and 49 more phone calls than the reporter himself recovered. The deleted information has been "super-wide" repaired. Subsequently, the reporter investigated four computer companies that can recover data, and they all agreed that 90% can recover the information that the external memory card of the mobile phone was deleted. Some people investigate privacy and "jump out" to scare the hostess. When the reporter mastered the method of recovering mobile phone data, I decided to help others recover mobile phone data in order to avoid possible accidental factors in recovering data. In the afternoon, in Science and Technology Street, Lanzhou, the reporter met a lady who came to restore the data of her mobile phone. During the conversation, the reporter learned that Ms. Zhang, 27, is a Chinese teacher in a primary school in Chengguan District. She has been using NOKIA66 10 for more than two years, and her mobile phone is her mobile database and notepad. But a few days ago, she accidentally formatted her mobile phone, and all the information was gone, even a few bank card passwords hidden in the notebook of her mobile phone could not be found. The reporter immediately promised to help her find the deleted information for free. According to the steps prompted by the data recovery software, the reporter installed the mobile phone for about 3 minutes, and all kinds of information were recovered one after another. Ms. Zhang saw that her information was indeed retrieved. Two completely different expressions of surprise and joy appeared on her face: "It's really amazing." Without saying a word, a group of recovered text messages jumped out. It was a dozen short messages from 1 17 to 1 155 in the morning of 2004. While blessing the owner, the other party mentioned that the owner had had abortion surgery before and had to go to the hospital for examination. Looking at this suddenly restored message, Ms. Zhang began to feel unnatural. She prevaricated that this group of messages must have been sent by someone using her mobile phone before, and immediately unplugged the connection between the mobile phone and the computer, quickly bid farewell to the reporter and disappeared into the sea of people. During the interview, some citizens thought that the information of journalists' guests was repaired and the extramarital affairs were exposed. Mobile phone data recovery software is indeed a secret weapon to recover losses, but it will cause mobile phone information leakage to some extent, especially in the second mobile phone market at this stage. According to Zhang Boss, who is engaged in recycling second-hand mobile phones, there are still people in the market who specialize in collecting personal privacy information. He is particularly worried about this. During the interview, the reporter came into contact with a private detective named Liu. He frankly blew himself up: finding and recovering mobile phone information is the "killer" for them to accept the investigation of "extramarital affairs" faster than other detective agencies. When we receive a "case" confirming an extramarital affair, we usually ask the parties to provide the mobile phone information of the investigated person. You know, the information recorded in the mobile phone is the most reassuring secret of the mobile phone owner. "Then he told reporters about the first time he used the repair software, when he received a difficult case. Entrusted by a lady, she investigated whether her lover had an affair. However, due to the special status of the respondent, it is difficult to get in touch with him. Detective Liu knows the outside world like the back of his hand, but he can't catch the most direct evidence. Just as she was about to give up the investigation, Detective Liu came across a data recovery software. With the help of the client, Detective Liu finished the investigation easily. Recovered the information inside, and photographed the tryst between the respondent and his lover according to the information. "If the information in the mobile phone is not restored, I may have to compensate the parties, which is not a small sum. "Detective Liu said. Detective Liu also told reporters that they are now used to getting basic information from mobile phones. The information they got from the mobile phone included the opposite sex phone number in the interviewee's mobile phone, frequently dialed phone numbers, some ambiguous short messages and even some more convincing evidence. "Based on this information, they can basically find close relationships." People in the industry turn to manufacturers for help to prevent leaks. How to prevent mobile phone from leaking? The reporter then consulted Wang Laoshi, a computer major at Lanzhou University of Technology. He told reporters that he had heard of mobile phone data recovery software and admitted that mobile phone data recovery technology does exist now. It is reported that many mobile phone manufacturers have set up special programs to recover messages, pictures, videos and other information in their mobile phones before they go on the market. As for how to prevent mobile phone leaks? Because the data of the mobile phone is stored in the flash memory, even if the battery of the device is used up or removed, the data will not disappear. In order to delete the data in the flash memory, the user must perform a "hard reset" even if the hardware is restored to the factory settings. Each mobile phone manufacturer uses different "hard reset" instructions, and some products need technicians or manufacturers for help to complete the "hard reset".
