What Are Spam Calls and SMS?
Spam calls and SMS are unwanted messages or phone calls, often promotional, scams, or robocalls that interrupt your peace or even expose you to fraud. Many MTN users in Nigeria receive these frequently—either from MTN itself or unknown numbers.
How to Block Spam Calls and SMS on MTN (2025 Methods)
Here are effective ways to stop spam messages and block nuisance calls on your MTN line:
1. Use MTN DND (Do Not Disturb) Code
MTN allows you to stop promotional and marketing SMS through their DND service.
-
To block all promo messages:
Send "STOP" to 2442 -
To choose specific categories (e.g., Banking, Sports):
Send "HELP" to 2442
You'll receive a list of categories and instructions.
This method is great for blocking network promotional offers and 3rd party SMS ads.
2. Use MTN Blacklist Feature
This allows you to block specific numbers that send spam messages or make spam calls.
