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.

• 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.

Recommended Apps

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.

Ready to reclaim your peace? Activate DND, use your phone’s built-in features, try a third-party app, and stay proactive in reporting spam numbers.

Purchasing Airtel airtime online is a quick and convenient way to stay connected without needing physical scratch cards or visiting a retail shop. Below is a simple guide on various methods you can use to buy Airtel airtime online. While steps may vary slightly depending on your country and banking options, the core process is similar across Africa.

1. Via Airtel Mobile Money App

Why Use It

If you have an Airtel Money account, using the official Airtel Money app (if available in your region) is often the most direct and secure method to top up your airtime.

Steps

1. Download/Update the App:
   • Find the Airtel Money (or MyAirtel) app in your device’s app store (Google Play Store for Android, Apple App Store for iOS).
   • Install or update to the latest version.
2. Log In or Register:
   • Open the app and log in with your phone number and PIN. If you don’t have an account, register by following the in-app prompts.
3. Select “Buy Airtime” or “Recharge”:
   • Look for an option like “Buy Airtime,” “Recharge,” or “Top Up.”
4. Enter Details:
   • Confirm the phone number you want to top up (this can be your own or someone else’s).
   • Input the amount of airtime you wish to purchase.
5. Confirm and Pay:
   • Review the transaction details, ensure your Airtel Money balance covers the purchase.
   • Tap “Pay” or “Confirm” to complete the transaction.
6. Check Airtime Balance:
   • You should receive a confirmation SMS. Dial the balance check code (e.g., *123#) to confirm the new airtime amount.

2. Using a Banking or Fintech App

Why Use It

Many African banks and fintech solutions offer direct airtime purchase options for multiple networks, including Airtel. This method is convenient if you have a bank account or e-wallet with enough funds.

Steps

1. Open Your Bank/Fintech App:
   • Log in to your mobile banking or fintech (e.g., Chipper Cash, Wave, etc.) app.
2. Find the “Buy Airtime” or “Airtime/Data” Section:
   • Look for a menu item named “Airtime,” “Top-up,” or “Buy Airtime.”
3. Select Airtel as the Operator:
   • Choose Airtel from the list of telecom providers.
4. Enter Amount and Phone Number:
   • Input the amount of airtime and confirm the Airtel phone number you want to recharge.
5. Confirm and Authorize Payment:
   • Check the details for accuracy.
   • Authorize the purchase with your app PIN, fingerprint, or other security method.
6. Verification:
   • Wait for the in-app confirmation and SMS message from Airtel stating your new balance.

3. Buying Online Through a Web Portal

Why Use It

If you don’t want to install an app, many websites allow direct top-ups using debit cards, credit cards, or mobile money. This is useful for topping up from a computer or if you’re outside the country.

Steps

1. Visit a Trusted Top-Up Website:
   • Examples might include the official Airtel site, third-party platforms like Recharge.com, Ding.com, or local aggregator sites.
   • Ensure the site uses HTTPS for security.
2. Enter Phone Number and Network:
   • Specify the Airtel phone number and confirm the network (Airtel).
3. Select or Input Amount:
   • Choose a preset airtime amount or type in a custom figure.
4. Payment Method:
   • Most sites accept card payments (Visa, Mastercard) or mobile wallet options (e.g., M-PESA, Airtel Money, etc., depending on the country).
5. Check Out and Confirm:
   • Provide your payment details, then review and confirm.
6. Confirmation:
   • You’ll see a success message onscreen, and the phone number recharged should receive an SMS indicating the updated balance.

4. USSD Shortcodes (If Linked to a Bank Account)

Why Use It

USSD (Unstructured Supplementary Service Data) codes work without internet, making it easy to buy airtime directly from your bank account or mobile money wallet.

Steps

1. Dial the USSD Code:
   • If your bank or Airtel Money supports USSD, dial the code (e.g., *185#, *140#, or *444#—the exact code depends on your country/region).
2. Select “Airtime” or “Buy Airtime”:
   • Navigate through the menu options.
3. Enter Phone Number:
   • Confirm the number you’re topping up if asked.
4. Enter Amount:
   • Specify how much airtime you want.
5. Confirm Payment:
   • Enter your mobile money PIN or bank PIN if prompted.
6. Check SMS Confirmation:
   • Wait for the text confirming a successful top-up.

Tips and Best Practices

• Keep PINs Secure:
  Whether using Airtel Money, bank apps, or USSD, never share your PIN with anyone.
• Check for Promotions:
  Airtel often runs bonus airtime or data promotions when buying via specific channels. Stay updated on these to maximize value.
• Regularly Track Transactions:
  Keep an eye on your bank statements or mobile money transaction logs to ensure accuracy and catch any fraudulent activity promptly.

Final Thoughts

Buying Airtel airtime online is a flexible and quick process—use the method that aligns best with your resources and preferences. Whether via Airtel’s own app, a banking or fintech platform, a web portal, or USSD, you can instantly top up without the hassle of physical cards.

Ready to simplify your Airtel top-ups? Choose any of these convenient methods, follow the prompts carefully, and enjoy effortless recharging anytime, anywhere!

7 Easy Ways to Fix Slow Wi-Fi at Home (African ISPs)

Experiencing sluggish Wi-Fi at home can be frustrating, especially when you’re trying to stream videos, work online, or keep multiple devices connected. Whether you’re using MTN, Telkom, Safaricom, Airtel, or another African ISP, these straightforward fixes can help boost your network’s performance.

1. Check Your Internet Plan and Speeds

Why It Matters

Sometimes slow Wi-Fi isn’t about your router or devices—it may be your internet plan. If your plan provides limited bandwidth, upgrading to a higher-speed package might be necessary.

What to Do

• Run a Speed Test: Use tools like Speedtest.net to see if your actual speed matches your plan.
• Contact Your ISP: If speeds are consistently below what you’re paying for, reach out to your ISP to discuss options or troubleshoot line issues.

2. Optimize Your Router Placement

Why It Matters

Wi-Fi signals weaken when they have to pass through walls or when there’s interference from appliances or metal objects. Placing your router strategically can improve coverage and speed.

What to Do

• Central Location: Position your router in a central area of your home.
• Elevate It: Place it on a shelf or mount it high on the wall—avoid cramped corners and floor-level spots.
• Away from Interference: Keep your router away from devices like microwaves, cordless phones, or Bluetooth gadgets that can disrupt Wi-Fi signals.

3. Change the Wi-Fi Channel or Band

Why It Matters

In areas with multiple overlapping Wi-Fi signals (apartments, urban neighborhoods), congestion on a specific channel or band can slow performance.

What to Do

• Router Settings: Log in to your router’s admin panel (consult the device’s manual) and navigate to the wireless settings.
• Channel Selection: Switch between 2.4GHz and 5GHz bands or try different channels (1, 6, 11 on 2.4GHz) to reduce interference.
• Auto Channel Mode: Some routers automatically select the least congested channel—enable this if available.

4. Update Router Firmware and Device Software

Why It Matters

Firmware updates can address security vulnerabilities, enhance performance, and fix bugs. Similarly, outdated device software can hamper connectivity.

What to Do

• Router Firmware Update: Check your router manufacturer’s website or the admin panel for firmware updates.
• Device Updates: Keep your smartphones, laptops, and tablets updated with the latest software and drivers.

5. Use Wi-Fi Extenders or Mesh Systems

Why It Matters

Large homes or buildings with thick walls can experience Wi-Fi dead zones. Extenders or mesh systems ensure consistent coverage.

What to Do

• Wi-Fi Extender: Place it midway between your router and the dead zone to boost signal strength.
• Mesh Network: Consider investing in a mesh Wi-Fi system if you have a large home. Mesh nodes create a unified network for seamless connectivity.

6. Secure Your Network

Why It Matters

An unsecured or weakly protected Wi-Fi network can invite unauthorized users, which slows speeds and poses security risks.

What to Do

• Strong Password (WPA2/WPA3): Use a robust passphrase instead of default or simple passwords.
• Disable WPS: Wi-Fi Protected Setup can be exploited; turn it off if not needed.
• Guest Network: Provide visitors with a separate guest network to protect your primary devices and data.

7. Contact Your ISP (When All Else Fails)

Why It Matters

Persistent slow speeds may signal a line issue, ongoing network congestion, or hardware faults. Your ISP can run diagnostics to identify the root cause.

What to Do

• Document Issues: Keep notes on times and frequencies of slowdowns.
• Request a Technician: If phone support can’t resolve your issue, ask for an on-site visit.
• Explore Alternatives: If your ISP repeatedly fails to provide stable speeds, consider switching to another provider or upgrading to fiber if available in your area.

Final Thoughts

Slow Wi-Fi can be fixed with a combination of simple in-home adjustments and proactive ISP communication. Whether you fine-tune router placement, upgrade your plan, or strengthen network security, these steps can help ensure a smoother, faster online experience—regardless of your location in Africa.
