In today’s world, mobile security is more important than ever. Your phone isn’t just a device for communication—it’s your bank, your identity, and your personal assistant. But have you ever wondered how secure your incoming calls are? If not, it’s time to pay attention. In this article, we will show you how to secure your incoming calls easily using simple tools and techniques.
📌 Why You Should Secure Incoming Calls
Whether you’re an Android or iPhone user, unsecured calls can expose your sensitive information. Cybercriminals are now using call spoofing, phishing, and caller ID manipulation to steal your data. Here’s why securing your calls is essential:
- 🔒 Prevent identity theft
- 🔒 Block spam and scam callers
- 🔒 Keep business and personal communication confidential
- 🔒 Protect from social engineering attacks
✅ 1. Use a Caller ID & Spam Protection App
One of the easiest ways to secure your incoming calls is by using caller ID protection apps. These apps identify unknown numbers and block fraudulent or suspicious calls before they even ring.
🔹 Best Apps to Try in 2025:
- Truecaller: Blocks spam, identifies callers, and even records calls (optional).
- Hiya: Advanced spam detection with reverse phone lookup.
- CallApp: Combines caller ID, call blocking, and recorder with cloud backup.
These apps use AI and crowdsourced data to alert you if a number is flagged by others.
✅ 2. Enable Built-in Call Protection (Android & iPhone)
Most smartphones now have built-in call screening features. Here’s how you can enable them:
📱 On Android (Pixel or Samsung):
- Go to Phone > Settings > Caller ID & Spam
- Toggle on Filter spam calls
- Use Google Assistant call screening for unknown numbers
🍏 On iPhone:
- Go to Settings > Phone > Silence Unknown Callers
- Use Focus mode to allow only selected contacts
This way, only your saved and trusted contacts can reach you.
✅ 3. Block Suspicious Numbers Manually
If an unknown number keeps calling, block it immediately. Here’s how:
Android:
- Open Call log
- Tap the number → Block/report spam
iPhone:
- Open Recent Calls
- Tap the “i” icon → Block this Caller
You can also create a whitelist of allowed numbers using third-party apps.
✅ 4. Encrypt Your Phone Calls
For those who want next-level privacy (especially for business or legal purposes), encrypted calls are a must. Apps like:
- Signal – End-to-end encrypted voice and video calls
- Telegram (secret chats) – Offers voice call encryption
- Threema – Anonymous and secure calling option
These apps ensure your calls are protected from eavesdropping.
✅ 5. Turn Off Call Forwarding and Voicemail Access
Hackers can exploit call forwarding to redirect your calls. Here’s what to do:
🔧 Disable Call Forwarding:
Dial these codes on your phone:
- ##002# – This disables all call forwarding settings
🔧 Secure Voicemail:
- Set a strong PIN code
- Avoid default PINs like 0000 or 1234
✅ 6. Be Wary of Call Spoofing
Call spoofing tricks you into believing that a call is coming from a legitimate source. If someone pretends to be your bank or a government office—never share OTPs or passwords on a call.
Tips to Avoid Spoofing:
- Always call back using the official contact number.
- Don’t trust caller ID completely—numbers can be faked.
✅ 7. Use a Second Number for Public Use
If you’re running a business, joining online groups, or listing on public directories, it’s better to keep your personal number private.
Apps That Offer Second Numbers:
- TextNow
- Burner
- Google Voice
This protects your primary number from harassment, marketing calls, and potential leaks.
