• 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.
