| How to Block WhatsApp and VoIP Calls on MTN Network |
In today’s digital world, WhatsApp and other VoIP (Voice over Internet Protocol) apps like Telegram, Skype, and Messenger have become very popular for making calls over the internet. While these platforms are convenient, some MTN users in Nigeria may prefer to block WhatsApp and VoIP calls to save data, avoid disturbances, or reduce distractions.
This guide will show you how to block WhatsApp calls and other VoIP services on the MTN network, step by step.
Why Block WhatsApp and VoIP Calls on MTN?
There are several reasons why MTN subscribers may want to block internet-based calls:
- Save Data – WhatsApp and VoIP calls consume internet data, which can be costly if you are on limited bundles.
- Prevent Disturbance – Sometimes WhatsApp calls come in during working hours or at night, causing distractions.
- Encourage Normal Calls – If you want your contacts to reach you via regular MTN calls instead of WhatsApp, blocking VoIP ensures they use your phone number directly.
- Parental Control – Parents may want to limit children from using WhatsApp calls excessively.
Methods to Block WhatsApp and VoIP Calls on MTN
1. Using MTN Call Control Service
MTN Nigeria provides call control services that allow users to restrict certain types of calls. While it does not directly say "WhatsApp," you can block internet-based services by controlling data usage.
- Dial 300 to reach MTN customer care.
- Request them to restrict VoIP calls or guide you on blocking such traffic.
2. Turn Off Data for WhatsApp
A practical way is to block WhatsApp’s access to mobile data:
- Go to Settings on your phone.
- Select Apps > WhatsApp.
- Tap on Data Usage.
- Turn off Mobile Data access (and Wi-Fi if needed).
This stops WhatsApp from making or receiving internet calls.
3. Using Firewall Apps (Android/iOS)
You can use third-party apps to block VoIP traffic on MTN:
- NetGuard (Android) – A free firewall app that allows you to block specific apps like WhatsApp from accessing data.
- Mobiwol Firewall – Another option to restrict VoIP services.
- iOS Screen Time Settings – On iPhone, you can use Screen Time to block WhatsApp calls.
Download apps like NetGuard from Google Play Store to set this up.
4. Deactivate VoLTE/VoIP Support
Some smartphones route calls via VoIP if VoLTE is enabled. Disabling it can help:
- Go to Settings > Connections > Mobile Networks.
- Turn off VoLTE Calls.
5. Use DND (Do Not Disturb) on MTN
MTN Nigeria also offers a Do Not Disturb service. While it mainly applies to SMS and promotional messages, you can customize it to limit disturbances. Dial:
- 2442 and follow the prompts to manage restrictions.
Alternative Option: Restrict WhatsApp Calls Only
If you don’t want to block WhatsApp completely but only stop calls:
- Open WhatsApp > Settings > Notifications.
- Turn off Call Notifications.
- Alternatively, block individual contacts from calling you via WhatsApp.
Final Thoughts
Blocking WhatsApp and VoIP calls on MTN is possible using different methods, from app settings to firewalls and MTN customer support. If you want to save data, reduce distractions, or encourage traditional voice calls, these options give you full control over how your MTN line is used.
