| How to Block Unwanted Calls on MTN Using USSD Codes |
Unwanted calls can be very annoying—whether they come from telemarketers, fraudsters, or even persistent contacts you no longer want to hear from. Thankfully, MTN Nigeria provides a simple way to block unwanted calls directly from your phone using USSD codes. This guide will walk you through everything you need to know about blocking numbers on MTN.
Why Block Unwanted Calls on MTN?
There are many reasons you may want to block calls, such as:
- Avoiding fraud/scam calls from suspicious numbers.
- Stopping telemarketing and spam calls that waste your time.
- Maintaining your privacy by blocking people you don’t want to reach you.
- Peace of mind—fewer interruptions during your busy day.
MTN Do-Not-Disturb (DND) Service
MTN has a Do-Not-Disturb (DND) feature that lets you stop promotional and unsolicited calls/SMS from reaching your line. If you’re tired of spam calls from marketers, this feature is very effective.
How to Activate DND on MTN
- Dial
*2442# - Choose the option to stop all promotional messages and calls
- You’ll receive a confirmation SMS once activated
This won’t block personal contacts, but it will stop spam calls and SMS from MTN partners.
How to Block Calls on MTN Using USSD
MTN also provides call barring services that help you block specific types of incoming or outgoing calls.
Steps to Block Incoming Calls with USSD
-
Dial
*35*0000#- This code blocks all incoming calls on your MTN line.
- Default barring PIN is 0000 (you can change it later).
-
To unblock, dial:
#35*0000#
How to Block International Calls
If you want to stop international numbers from disturbing you:
- Dial
*331*0000#
To deactivate:
- Dial
#331*0000#
How to Change Your MTN Call Barring PIN
For security reasons, you should change the default PIN (0000) to a personal one:
- Dial
**03*330*OLD PIN*NEW PIN*NEW PIN#
Example: **03*330*0000*1234*1234#
Using Your Phone’s Built-in Call Blocking
Apart from MTN’s USSD codes, you can also block specific numbers directly from your phone:
- On Android: Go to Phone App > Call History > Select Number > Block/Report Spam
- On iPhone: Go to Phone App > Recent Calls > Info > Block this Caller
This method is best for blocking individual numbers.
