Smart Call Blocker vs PrefixBlock

Block unwanted calls with surgical precision using pattern matching. Unlike crowd-sourced blockers, Smart Call Blocker lets YOU define exactly which numbers to block using wildcard patterns. Block entire number ranges with a single rule. FEATURES: • Pattern matching — Use * as a wildcard for any digit • Block number ranges — e.g., 1900****** blocks 1 million 1900xxxxxx numbers in one rule • Background loading — Large blocklists keep loading after you leave the app, with a Live Activity on iOS 26 • SMS spam filter — The same patterns silently move junk texts from unknown senders to the Junk tab • Duplicate cleanup — One-tap removal of patterns already covered by a broader rule • 213 countries — Full E.164 international format support • Rule labels — Name each rule so you remember why you blocked it • System-level blocking — Powered by Apple CallKit PREMIUM: • Up to 7 wildcards per pattern — block a 10-million-number range in one rule (you confirm before saving) • Unlimited blocking rules • Block up to 1 billion numbers in total (free: 6 million); the real limit depends on your device • Access to all 213 countries • 136 pre-built spam templates across 25 countries • Siri Shortcuts and automation • Priority support FREE: • 5 blocking rules • iCloud Sync across all your devices • Block up to 6 million numbers • Single-country lock (your first rule's country) • Pattern matching with up to 6 wildcards (1 million numbers per rule) • Allow list and import/export • Weekly blocking report HOW IT WORKS: 1.

• 17 languages and 69 countries — block prefixes at home and abroad Chặn Đầu Số identifies and warns you about spam calls and texts by prefix. When a number from a prefix you added calls, the app shows a "Spam" label right on your screen. Other apps only block one number at a time — block this one, they call from the next. Chặn Đầu Số works differently: you block the whole prefix (024899, for example) and the app covers every number starting with it. Spam operations buy numbers in bulk blocks, so blocking by prefix hits them at the source. Key features: • Block calls by landline prefix — 024 (Hanoi), 028 (Ho Chi Minh City) and more • Filter spam SMS from those same prefixes too • Quick-block suggestions for the most common telesales prefixes — one tap • "Warn only" mode — show a label instead of hard-blocking, your choice • Bilingual Vietnamese / English, switch right inside the app Privacy first: • Does NOT read or upload your contacts • NO ads, NO tracking • Your block list stays on your device Free for up to 500,000 numbers. Upgrade to Premium (monthly / yearly / lifetime) to block without limits. Note: iOS handles blocking silently, and it does not block numbers saved in your Contacts.
