How to Block Spam Calls in Nigeria (DND & Apps)

Dealing with spam calls in Nigeria can be frustrating and time-consuming. Fortunately, there are simple ways to reduce unwanted calls, such as activating Do Not Disturb (DND) services on your mobile network and using third-party call-blocking apps. Below is a step-by-step guide to help you block spam calls effectively.

1. Activate Do Not Disturb (DND) on Your Network

Why Use DND?

The Nigerian Communications Commission (NCC) mandates that mobile operators provide a Do Not Disturb service. Enabling DND helps block unsolicited SMS and promotional calls from various brands and advertisers.

Steps to Activate DND (SMS):

1. Check Your Network’s Shortcode:
   • MTN Nigeria: Send STOP to 2442
   • Glo: Send STOP to 2442
   • Airtel Nigeria: Send STOP to 2442
   • 9mobile: Send STOP to 2442
2. Confirm Activation:
   • You should receive a confirmation SMS indicating that DND is now active.
3. Partial vs. Full DND:
   • Full DND: Blocks all promotional messages and calls.
   • Partial DND: Allows certain categories of messages (e.g., banking alerts, religious messages, etc.). For partial DND, send the relevant keyword (e.g., HELP to 2442 to see the available categories).
4. Check DND Status or Opt Out:
   • For some networks, you can dial *2442# or re-send an SMS (e.g., STATUS to 2442) to see whether you have Full or Partial DND.
   • To opt out or customize DND, send ALLOW or the specific category codes to 2442.

2. Use Smartphone Features to Block Calls

Android Phones

• Block Numbers via Call Settings:
  1. Open the Phone or Dialer app.
  2. Go to Settings → Blocked Numbers or Call Blocking.
  3. Add the phone number you want to block or enable Block Unknown/Private Numbers.
• Do Not Disturb Mode:
  While primarily for silencing notifications, you can configure Do Not Disturb to allow calls only from saved contacts.

iPhones

• Block a Number via Recent Calls:
  1. Open the Phone app, tap the Recents tab.
  2. Tap the info icon (i) next to the unwanted caller.
  3. Scroll down and select Block this Caller.
• Silence Unknown Callers (iOS 13+):
  1. Go to Settings → Phone.
  2. Toggle on Silence Unknown Callers to send calls from numbers not in your contacts, messages, or mail straight to voicemail.

3. Install Third-Party Call-Blocking Apps

Why Use Apps?

Call-blocking apps leverage large databases of reported spam callers, making it easier to identify and block unwanted numbers automatically.

2. Grant Permissions:

3. Configure Block Settings:
   • Customize which types of calls to block (spam, unknown, hidden numbers, etc.).
4. Keep the App Updated:
   • Spam databases regularly update. Ensure the app is always on the latest version.

4. Report Spam Calls

• NCC Complaints Portal:
  If unwanted calls persist despite enabling DND, consider filing a complaint on the Nigerian Communications Commission (NCC) website.
• Network Support:
  Reach out to your mobile network’s customer care line or social media channels to lodge a complaint about persistent spam calls.

5. Best Practices for Minimizing Spam

1. Don’t Share Your Number Publicly:
   Avoid posting your phone number on social media or websites.
2. Opt Out of Promo Lists:
   When registering on e-commerce sites or events, uncheck marketing consent boxes if you don’t want promotional calls.
3. Stay Vigilant:
   Never disclose personal or financial information over the phone to unverified callers.

Final Thoughts

Blocking spam calls in Nigeria is easier when you combine the Do Not Disturb service, phone-based call blocking, and a reliable spam-blocking app. By leveraging these methods, you can significantly reduce annoying and potentially fraudulent calls and enjoy a quieter, safer communication experience.
