CleanCall is a Vietnamese application designed for Vietnamese users to identify, block unwanted calls, and filter spam SMS messages. With the prevalence of scams and unknown numbers in Vietnam, this app aims to enhance user experience by automatically categorizing incoming calls and messages as spam, credit, or scams before they are answered. Users can also block unwanted numbers, proactively report spam calls, and update spam numbers daily without needing to access their contacts. CleanCall Premium offers additional features such as automatic call blocking, spam number updates, and community-contributed spam lists.

CleanCall requires users to activate the Call & ID option in their phone settings to fully utilize its call blocking and identification capabilities.
