What is the Use of Mobile Network Duration?
Mobile network duration is an important indicator for measuring the age of a mobile number's usage, and it has practical value in various scenarios:
- User Profile Analysis: Operators and businesses can understand user loyalty and stability through network duration. Users with longer network durations are generally 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 fields such as finance and credit, network duration is sometimes used as one of the auxiliary indicators for assessing user credit risk. A longer network duration may imply a more stable and reliable user identity.
- Fraud Identification: Numbers that have been active for a short period are more likely to be used for telecommunication fraud and other illegal activities, so network duration can serve as a reference factor for identifying risky numbers.
