Various Apps are available for screening telemarketing calls. These Apps generally collect telemarketers’ numbers through reports from the public and set up relevant databases. When there is an incoming call, these Apps will assist the user to identify whether it is a telemarketing call by checking the calling number against the databases.
Before installing and using call-filtering Apps, please take note of the following:
- Databases used by various call-filtering Apps mainly rely on reports by the public. There is no guarantee that these databases are accurate or complete.
- Understand more about the conditions of use and the permission requests of the Apps.
Moreover, you may ask your telecommunications service providers if they are providing similar call-filtering services and the relevant details.
