Call Blocker - Stop spam calls

Getting unwanted spam calls? Check whether other people have reported the number and block calls you do not want to receive. Call Blocker helps you block spam calls and look up suspicious phone numbers. Check community reports about unwanted telemarketing calls and potential phone scams, and choose which calls to block. PROTECT YOURSELF FROM SPAM CALLS Block calls from numbers identified as spam by UnknownPhone.com and its community. Update the spam number list in the app to include newly identified numbers and block their calls automatically. CHECK SUSPICIOUS PHONE NUMBERS Look up a number and read available information and community reports before calling back. Results depend on the information contributed by the community; not every number will have a result. CHOOSE WHICH CALLS TO BLOCK Alongside spam protection, choose the blocking options you need: • Block numbers that start with a specific prefix or sequence of digits. • Block calls from numbers that are not in your contacts. • Block international calls from numbers that are not in your contacts. • Block calls with a hidden number or no caller ID. • Block individual numbers you add to your personal block list. Enable the options that suit you and manage your blocked numbers in the app. SHARE YOUR EXPERIENCE Received a suspicious call? Report the number and explain what happened to help other people recognize unwanted calls and possible scams. SET UP YOUR CALL PROTECTION Follow the setup steps and grant the permissions needed for the features you choose. Functionality may vary depending on your device and Android version.
