Can I find personal information after I cancel my mobile phone number?

Personal information cannot be found after the mobile phone number is cancelled. After the mobile phone number is cancelled, all personal information will be emptied, including call records and SMS records. However, if legal cases are involved or relevant departments inquire according to law, relevant information may still be found in business files. It is illegal for individuals to inquire about the information of cancelled mobile phone numbers privately, which is an invasion of personal privacy. Mobile phone number, also called mobile phone number, is a series of numbers consisting of 1 1 digits, which are uniformly numbered by the Ministry of Information Industry. No matter in GSM system or CDMA system, digital mobile phone users will get a mobile phone number card when they access the network.
