CallWall: Spam Call Blocker

Block spam calls and scam texts free. No subscription, no ads, no selling your data. 690,000+ known spam numbers, blocked automatically and updated every day.

CallWall is a community-powered spam call and text blocker that actually explains why a number is flagged — not just "Spam Likely." Every number in our database shows a full confidence score from 0–100, so you know exactly how dangerous a caller is.

SEE THE THREAT BEFORE YOU ANSWER Borderline spam calls don't just ring blind — CallWall puts the score right on your call screen, like "Robocall · 75," so you decide at a glance whether to pick up. The most dangerous numbers never ring at all.

HOW IT WORKS CallWall combines real data and community intelligence into a single 0–100 confidence score for every number:

• Government Data — Our database is seeded from over 868,000 FCC consumer complaint records and updated daily with new complaints, covering robocalls, telemarketers, scam texts, and political calls.
• Community Reports — Verified users submit reports with a spam category and description, adding to the database over time.
• Verification System — Community-submitted numbers are reviewed before being added to the verified block list, keeping false positives out.

BLOCK SPAM CALLS Stop robocalls, telemarketers, political calls, and scam callers before your phone rings. Adjustable blocking threshold from 70 to 99.

FILTER SPAM TEXTS CallWall filters scam texts from unknown senders straight to your junk folder — and inspects the links inside them, too. Every link is checked against 320,000+ known scam and phishing sites, right on your device, so dangerous texts get caught even when they come from a number you've never seen. Fake delivery alerts, phishing links, prize scams, bank impersonation — filtered before they clutter your inbox. The text of your messages never leaves your phone.

CHECK ANY LINK, INSTANTLY Not sure about a link? Paste it into CallWall — or share it straight from Messages — and get an instant verdict against 320,000+ known scam sites. Free, unlimited, and 100% on your device. The link never leaves your phone.

LOOK UP ANY NUMBER Search our database of 690,000+ verified spam numbers to see the confidence score, spam type, and total community reports. 3 free lookups per week.

COMMUNITY REPORTING Spot a spam number not in our database? Report it. Your submission enters a review queue, and once verified, it's added to the block list for every CallWall user.

Got a scam text? Paste it and CallWall pulls out the dangerous links on your device — only the links are shared, never your message. Once the community confirms them, those links are blocked for every CallWall user.

COMMUNITY LEADERBOARD Report spam numbers to earn badges and climb the public leaderboard. From "Newcomer" to "Elite Defender."

YOUR DATA STAYS YOURS CallWall never sells your data. Call blocking and SMS filtering happen entirely on your device — scam links are matched locally, and the text of your messages is never uploaded. Your personal information is never shared with other users.
