Unwanted calls can be frustrating, especially when they come from telemarketers, spam numbers, or unknown callers at inconvenient times. Many MTN Nigeria users experience frequent promotional calls, scam attempts, or repeated disturbances that affect productivity and peace of mind.
Fortunately, MTN Nigeria provides several ways to block unwanted calls, including the Do Not Disturb (DND) service, call barring options, and phone-based solutions. In this blog post, you’ll learn how to block unwanted calls on MTN Nigeria using simple and effective methods.
Why You Receive Unwanted Calls on MTN Nigeria
Before blocking unwanted calls, it helps to understand why they happen. Common reasons include:
- Promotional calls from service providers
- Marketing calls from third-party companies
- Robocalls and spam calls
- Scam or fraudulent numbers
- Unknown callers dialing randomly
MTN’s DND service is designed specifically to reduce these disturbances.
Method 1: Activate MTN Do Not Disturb (DND) Service
The MTN DND service is the most effective way to stop promotional and unsolicited calls and SMS messages.
How to Activate Full DND on MTN
To block all promotional calls and SMS:
- Dial
*2442# - Or send “STOP” to 2442
Once activated, you will stop receiving promotional calls and messages from MTN and third-party advertisers.
How to Check DND Status
- Dial
*2442# - Select Status Check
This lets you confirm whether DND is active on your line.
Method 2: Activate Partial DND on MTN
If you still want to receive certain messages (such as banking alerts or service notifications), MTN offers Partial DND.
Partial DND Categories Include:
- Banking/Financial alerts
- Health messages
- Education information
- Religious messages
- Government alerts
How to Activate Partial DND
- Dial
*2442# - Choose Partial DND

Method 3: Block Specific Numbers Using Your Phone
If unwanted calls come from specific numbers, you can block them directly from your mobile device.
On Android Phones
- Open the Phone app
- Tap Recent Calls
- Select the number you want to block
- Tap Block / Report Spam
On iPhones
- Open Phone → Recents
- Tap the info (i) icon next to the number

This method is useful for repeatedly calling numbers that bypass DND.
Method 4: Use MTN Call Barring (SIM-Based)
MTN call barring allows you to restrict certain types of incoming calls.
Common Call Barring Options
- Block all incoming calls
- Block international incoming calls
- Block calls while roaming
To activate SIM-based call barring, you may need to:

This option is usually recommended for advanced call control needs.
Method 5: Use Third-Party Call Blocking Apps
You can also block unwanted calls using trusted call-blocking apps.
Popular Call Blocking Apps

- Hiya
These apps help identify spam numbers and automatically block suspected scam calls. However, ensure you download apps only from official app stores and review their privacy policies.
How to Deactivate MTN DND (If Needed)
If you ever want to start receiving promotional calls again:
- Dial
*2442# - Or send “START” to 2442
Your DND service will be deactivated immediately.
