Description
Let’s be real — your phone is supposed to be your space. Your connection to friends, family, work. But lately, it feels more like a public nuisance hotline. The second you think you’ve silenced one spammer, three more pop up with fake warranty offers, sketchy loan deals, or that robotic voice asking about your car’s extended warranty. It’s exhausting. It’s invasive. And it’s time to fight back. That’s where Unknown Call & Contact Blocker Mod comes in, not as another app, but as your personal digital bouncer. This isn’t about just declining calls; it’s about reclaiming the peace and privacy your smartphone was meant to provide. With the Pro features unlocked right out of the gate in this mod, you’re getting a premium defense system against the modern plague of unwanted communication.
Why Your Phone Deserves This Bodyguard
Think of Unknown Call & Contact Blocker Mod as the most aggressive, intelligent spam filter you can get for your calls and contacts. While your default phone app might show you a number and leave you to guess, this app works in the background, cross-referencing massive databases of known spammers, telemarketers, and fraud numbers. But it goes deeper. It learns from you. Every time you mark a call as spam, it gets smarter, building a personalized blacklist that protects you more effectively over time. The core loop is beautifully simple: install, set your rules, and forget. The app does the grinding for you, silently screening every incoming call, letting through only the people you want to talk to. It blew up because it solves a universal, daily frustration with a set-it-and-forget-it elegance that actually works.
Unlocking the Pro Power: Your Mod Menu
With the mod APK, the entire Pro toolkit is unlocked from the moment you install. No subscriptions, no trial periods. Here’s how to weaponize it. First, dive into the app’s settings immediately after opening. You’ll see options grayed out in the standard version are now fully active. The key is the Blocking Rules section. This is your command center. To activate the most powerful feature—blocking all unknown/private numbers—go to Blocking Rules → Block Hidden Numbers and toggle it on. Want to be more surgical? Head to Block by Prefix or Pattern. Here, you can block entire area codes or number sequences common to spammers in your region. The mod also unlocks the Automatic Call Recorder for Pro. To use it, go to Settings → Call Recording → Enable Auto Record. You can set it to record all calls, only unknown numbers, or specific contacts. This is a clutch feature for keeping evidence of harassment or simply for note-taking.
Pro-Tip: The Silent Kill Switch
Most users just block and move on, but the real power move is using the “Silently Reject” option. Found in the Call Blocking Action settings, this makes blocked calls die instantly on the caller’s end—they’ll hear one ring or go straight to voicemail without ever ringing your phone. This saves your battery, prevents distraction, and, psychologically, makes the spammer think the number is dead, potentially getting you off their list faster than a loud, obvious rejection.
Context & Performance: Making It Work For You
This mod of Unknown Call & Contact Blocker Mod is optimized for Android 5.1 and up, but it runs lean. It won’t drain your battery like some overzealous security apps because it’s not constantly running heavy scans; it acts at the moment of the incoming call. Compared to other blockers, this one stands out for its deep integration with your contact list and its pattern-based blocking, which is rare in free apps. If you’re on a mid-range or older device, go into the app’s settings and disable “Cloud Lookup” if you’re on a slow data connection; the local database and your personal blacklist will do most of the heavy lifting. The beauty of this mod is it delivers what paid subscription services like Truecaller’s premium tier offer, but locally on your device, often with better battery efficiency.
Getting It On Your Phone: The Fast Guide
Since this is the modded Pro APK, you won’t find it on the Play Store. Don’t worry, sideloading is simple. First, before you download anything, go to your phone’s Settings > Security (or Apps & Notifications) and enable “Install from Unknown Sources” or “Install unknown apps” for your browser or file manager. Next, download the Unknown Call & Contact Blocker Mod APK file (version 1.6.0, about 6.5 MB) from a trusted mod site. Once downloaded, open the file. Your phone will ask for confirmation—tap Install. After a minute, you’ll see the “App installed” message. Open it, and you’re in. The Pro features are already active; no key, no login required. You can now immediately configure your fortress. Remember, after installation, you can toggle that “Unknown Sources” setting back off for security.

Mod Review
Editor's Take: As someone whose phone used to buzz non-stop with “Potential Spam” alerts, finding a real solution felt like a quest. Unknown Call & Contact Blocker Mod isn’t just another app; it’s peace of mind, automated. The modded Pro version transforms it from a useful tool into an essential utility. It works so seamlessly you’ll forget it’s there—until you realize you haven’t been interrupted by a robocall in weeks. This is the digital equivalent of a great spam filter for your inbox, but for your actual voice line.
- Pros:
- Truly Set-and-Forget: Once you configure your blocking rules (like blocking all private numbers), it operates silently in the background with zero daily input needed.
- Pro Features That Matter: The automatic call recorder and SMS filter are game-changers, often locked behind steep subscriptions in other apps.
- Lightweight Performance: Unlike some bloated security suites, this app has a minimal footprint on battery and RAM, even with constant monitoring enabled.
- Pattern Blocking is OP: The ability to block by number prefix (e.g., an entire area code known for scams) is a level of control most free apps don’t offer.
- Cons:
- Update Roulette: Being a mod APK, future official updates from the developer might break some Pro features until the mod is updated.
- Interface is Functional, Not Fancy: The UI is straightforward and gets the job done, but it lacks the polished design of some bigger-name apps.
- Cloud Features May Lag: The community spam database relies on user reports, so brand-new scam numbers might slip through for a day or two before being flagged.
Final Verdict: For anyone tired of being a telemarketer’s target, this mod is a must-install. It delivers premium, paid-level functionality for free, with incredible efficiency. ⭐⭐⭐⭐½ (4.5/5 Stars)

FAQ
Is this mod APK of Unknown Call & Contact Blocker safe to install on Android?
Yes, this specific mod APK from a reputable source is generally safe. It only unlocks the Pro features already present in the app's code; it does not contain additional malware or spyware. As with any mod, always download from trusted mod community sites and run a quick scan with your device's security app after installation for extra peace of mind.
Do I need to root my phone to use this mod?
No root needed! This mod works perfectly on standard, non-rooted Android devices (Android 5.1 and higher). The installation process is simple sideloading—just enable 'Install from Unknown Sources' for your browser, download the APK file, and install it like any other app.
How do I install the mod APK step by step?
1. Go to Phone Settings > Security/Privacy > Enable 'Install from Unknown Sources' for your browser or file manager. 2. Download the 'Unknown Call & Contact Blocker' APK file. 3. Open your file manager, find the downloaded .apk file, and tap it. 4. Tap 'Install' on the prompt. 5. Once installed, open the app—the Pro features will already be active and ready to configure.
How does the app's blocking database work? Does it use my data?
The app uses a two-layer system. First, it checks a built-in and community-updated online database of known spam numbers (this uses a small amount of data). Second, and more importantly, it builds a personal blacklist based on calls YOU block. You can disable the cloud lookup in settings to rely solely on your personal list and save mobile data.
Will using this mod get my phone number or service banned?
No. Using a call blocker app, even a modded one, is completely legal and within your rights as a consumer. It operates locally on your device to screen calls; it does not interact with your carrier's network in a way that could get your number banned. Carriers themselves often offer similar, but more basic, spam protection services.
