Chặn cuộc gọi rác & lừa đảo

Are you frequently bothered by spam calls, unknown numbers, advertising calls, or numbers with signs of fraud? Blocking a number only to have the caller continue using a different number?

Spam & Scam Call Blocker allows you to proactively filter calls by phone number, prefix, or number sequence. The app also synchronizes a database of sourced alert numbers to help protect users from suspicious calls.

FLEXIBLE CALL BLOCKER

• Enter the entire phone number or prefix to block.

• Block numbers starting with a prefix, for example, 028 or 035.

• Block numbers containing or ending with a number sequence.

• Choose to apply the rule to all SIMs or individual SIMs when Android provides sufficient information.

• Add exception numbers so important people can still call.

SOURCE-BASED SCAM NUMBER DATABASE

• Automatically synchronizes the list of flagged numbers and prefixes.

• Displays the reason, source name, and reference link when data is available.

• Saves the most recent list on your phone for continued reference even when the network is down.

• Allows users to submit suspicious numbers and reasons for administrator verification before adding them to the shared database.

EASY TO CHECK AND MANAGE

• View the history of blocked calls.

• See which rules matched incoming calls.

• Add, edit, or delete blocking rules as needed.

• Clear Vietnamese interface, suitable for both the elderly and those with limited tech experience.

HOW TO USE

1. Install the application and grant call screening roles according to Android instructions.

2. Enable background filtering.

3. Add numbers, prefixes, or rules to block.

4. Check the alert number pool and blocked call history directly within the app.

IMPORTANT NOTE

The ability to identify the SIM receiving the call depends on the information provided by each Android device. No app can identify or block 100% of scam calls because phone numbers and scams are constantly changing. Do not provide passwords, OTP codes, or transfer money only when requested over the phone; contact the caller through an official channel for verification.
