What is the use of mobile network duration?

Mobile network duration is an important indicator for measuring the "age" of a mobile number's use, and it has practical value in various scenarios:

• User Profile Analysis: Operators and enterprises can understand user loyalty and stability through network duration. Users with longer network duration are usually considered high-quality, high-value customers.
• Precise Marketing: Differentiated marketing strategies can be designed for user groups with different network durations. For example, offering exclusive discounts to old users to increase renewal rates, and recommending entry-level packages to new users.
• Risk Control: In finance, credit, and other fields, network duration is sometimes used as one of the auxiliary indicators for evaluating user credit risk. Longer network duration may mean that the user's identity is more stable and reliable.
• Fraud Identification: Numbers with shorter network duration are more likely to be used for telecommunication fraud and other illegal activities, so network duration can be used as a reference factor for identifying risky numbers.
