Introduction

In today’s digital world, your phone is both a lifeline and a potential vulnerability.

While the Communications Authority of Kenya (CAK) continues to implement regulations to curb such behavior, it’s crucial for individuals to take personal action.

This article will walk you through how to block unwanted numbers on your phone in Kenya, using both smartphone and non-smartphone methods. Whether it’s a pesky ex, a relentless telemarketer, or a fraudster, you’ll find the tools you need to take control of your privacy.

Why Blocking Unwanted Calls Matters

Blocking numbers isn’t just about convenience—it’s about security, mental peace, and control. In Kenya, cyber fraud and scam calls have been on the rise, often targeting vulnerable groups. Here are some common issues:

• Mobile money scams (M-PESA)

• SMS fraud promising fake prizes

• Persistent telemarketing calls

• Harassing personal contacts

By blocking these numbers, you avoid stress, financial loss, and potential identity theft.

Method 1: Use Built-in Features on Android and iPhone

For Android Users

Most modern Android phones have a built-in feature to block numbers. Here’s how to do it:

Option 1: From Call Log

1. Open the Phone app.

2. Go to Recents or Call History.

3. Tap the number you want to block.

4. Tap Details (info icon).

5. Choose Block number or Report as spam.

Option 2: Through Settings

1. Go to Phone Settings > Blocked Numbers.

2. Add the unwanted number manually.

Tip: Different brands like Samsung, Xiaomi, or Infinix may label these settings differently, but the functionality is similar.

For iPhone Users

1. Go to the Phone app and tap Recents.

2. Tap the info icon (i) next to the number.

3. Scroll down and tap Block this Caller.

To manage blocked contacts:

• Go to Settings > Phone > Blocked Contacts.

Method 2: Use USSD Codes from Mobile Operators

In Kenya, all major telecoms—Safaricom, Airtel, and Telkom—offer USSD-based services or apps to help manage calls.

Safaricom

Currently, Safaricom does not offer a universal USSD code to block calls, but the MySafaricom App includes features to manage contact preferences and report spam.

Airtel Kenya

Airtel customers can use Call Manager Services. To activate:

• Dial *100# > Call Services > Blacklist (if available on your plan)

Alternatively, download the Airtel Thanks App for more control.

Telkom Kenya

Use the My Telkom App to block numbers or manage DND (Do Not Disturb) settings. You can also contact Telkom’s customer service for manual blacklisting.

Important Note: Telecom providers may charge for premium call-blocking services.

Method 3: Install Call Blocking Apps

For advanced protection, use third-party apps available on the Google Play Store or Apple App Store.
