How to Block Collect Calls (Call Me Back Calls) on MTN

If you are an MTN subscriber in Nigeria, you’ve probably received a Collect Call (also known as “Call Me Back” or “Please Call Me” request) before. This feature allows someone without airtime to push the cost of the call to you. While it may be useful in emergencies, it can also become annoying or costly if friends, family, or even strangers keep sending them too often.

The good news is that MTN allows you to block collect calls on your line. This article explains what MTN Collect Calls are, why you may want to block them, and how to do it step-by-step.

What Are MTN Collect Calls?

MTN Collect Call is a service that lets the receiver pay for the call instead of the caller.

Example: If someone dials your number without airtime and selects the “Collect Call” option, you’ll get a message asking if you want to accept and pay for the call.
If you accept, your airtime is deducted for the duration of the call.
If you decline, the call ends, but some people may keep trying repeatedly.

While it’s helpful in emergencies, it can become a burden if overused.

Why Block Collect Calls?

Here are some reasons you may want to stop Collect Calls on MTN:

Prevent Unwanted Charges – Avoid losing airtime to calls you never intended to pay for.
Stop Spam Calls – Some people misuse the feature to disturb others.
Better Control of Your Airtime – Ensure your airtime is used only for your own calls, not for others.
Peace of Mind – No more annoying “Would you like to pay for this call?” pop-ups.
