CleanCall: Caller ID & Block

CleanCall is a Vietnamese caller ID and spam protection app that helps users identify unknown numbers and filter SMS for scams and spam before answering. It automatically labels numbers as spam, scam, or related categories, and lets you block unwanted callers directly from the app without needing access to your contacts.
