Call blocker: block spam, robocalls & unknown numbers by area code or prefix.
Get your peace back: Block-Spam is the call blocker that stops spam calls, robocalls and scams before your phone even rings. Only the people who matter get through, and your contacts never leave your phone. YOUR PHONE IS YOURS AGAIN • Automatic spam call blocking: known spam numbers are cut off automatically, in a meeting, at dinner or while you sleep. • Know who's calling before you answer: an alert tells you when a call is likely spam. • Identify unknown numbers: look one up and our AI tells you who is calling and why (telemarketing, debt collectors, likely scam), without ever sending your full number. • Never miss an important call: numbers on your allow list (your doctor, your kids' school, the delivery driver) always get through. • Block whatever you want: your own blacklist, hidden and unknown numbers, or silence calls instead of hanging up. • Reply without picking up: send an automatic text to the calls you reject. YOUR PRIVACY, FOR REAL No account, no sign-up: it works from the first minute. We don't upload your contacts and we don't sell your data. FREE, NO FINE PRINT The free version keeps you fully protected from day one. If you ever want more, optional advanced features are available. FAQ Is it free? Yes. Blocking spam calls costs nothing and needs no subscription. Does it upload my contacts? No. Your address book stays on your phone and you don't need an account. Can I block hidden or unknown numbers? Yes, with a single tap in the settings. Questions? support_android@block-spam.com
