How do you activate call forwarding for MTN, Airtel, Glo and 9Mobile
The general activation process for Nigerian mobile networks uses standard GSM codes. Each type of call forwarding has its own purpose and unique code.
Unconditional call forwarding
This option redirects all incoming calls to another number immediately, without ringing your phone. It is ideal when you want every call sent to a secondary line, such as when you are using another phone.
- To activate MTN SIM cards, Glo, and 9Mobile, dial **21*ForwardNumber#, then press SEND. For example **21*08012345678#.
- To activate call forwarding for Airtel, dial **002*ForwardNumber#, then press SEND. For instance: **002*08012345678#.
Once entered, your network will send a confirmation message to confirm that call forwarding is active.

Conditional call forwarding
This only redirects calls under certain conditions. You can activate each scenario individually depending on your needs:
- When busy: This forwards calls when you are already on another call. To activate, you should dial **67*ForwardNumber#, then press SEND.
- When unreachable: This forwards calls when your phone is switched off or out of coverage. To activate it, dial **62*ForwardNumber#, then press SEND.
- When not answered: This forwards calls when you do not answer after a few rings. To activate it, dial **61*ForwardNumber#, then press SEND.
After entering any of these codes, wait for a confirmation message from your mobile network. You must repeat the steps for each SIM if your device uses dual SIM cards.

How to deactivate call forwarding on Android
Disabling call forwarding on Android is a straightforward process. However, the steps may vary slightly depending on your phone brand. For this guide, Google’s default phone app was used to explain how to cancel call divert settings.
If your device supports dual SIM, you must repeat the process for each SIM card individually. Follow the steps below:
- Open the phone app from your home screen or app drawer.
- Tap the three-dot menu in the top-right corner, then select ‘Settings’.
- Choose the SIM card you want to manage.
- Tap on ‘Call forwarding’ to view the active forwarding rules.
- You will see options such as: Always forward, When busy, When unanswered, and When unreachable. Tap on each one, then press ‘Turn Off’ or ‘Disable’ to deactivate it.
- If all four options are active, make sure to turn off each one to fully cancel all diverts.

On iPhone, call forwarding works if your line uses a GSM network. If you use a CDMA network, you may need to contact your carrier for help. While there is no universal call divert code for iPhone, here is how to enable the feature through your settings:
- Unlock your iPhone and navigate to ‘Settings’, then tap ‘Phone’.
- Select ‘Call Forwarding’, then toggle it on. A forwarding icon will appear in the status bar when active.
- If your device uses two lines, choose the one you wish to manage.
- Tap ‘Forward To’, enter the phone number, and tap ‘Back’ to save.
Note that you must be connected to your cellular network when enabling call forwarding, or it will not work. If your mobile provider supports conditional call forwarding (e.g., when busy or unreachable), contact them directly to configure those settings.
How to deactivate call forwarding using dial codes
If you prefer using short codes instead of navigating through settings, you can use a universal dial code that works across MTN, Airtel, Glo, and 9Mobile. To cancel all active call forwarding on any of these networks, follow the below steps;
- Open the phone app
- Enter the code: ##002#
- Press the Call/Send button
- Once successful, this code will remove all types of call forwarding on the SIM.
How to know if you have deactivated call forwarding
If you are unsure whether call forwarding has been turned off, you can verify in the following ways:
- Check for call forwarding notifications: If the “Call forwarding active” message no longer appears in your notification panel, the feature is off.
- Ask someone to call you: If your phone rings directly without delays or messages like “call is being forwarded,” then call forwarding has been deactivated.
- Inspect the call forwarding settings: Go back to the Phone app settings and check if all call forwarding options show as inactive.
- Contact your service provider: If you still have doubts, reach out to your network provider for confirmation and assistance.
How do you know if your call is forwarded to another number?
If you suspect someone has activated call divert on your phone, or you want to check it yourself, here are the signs to look out for:
- Persistent notification: If your device shows “Forwarding all calls” or similar messages, it means call forwarding is active.
- Voice prompt from the network: When someone calls you and hears, “Please wait while your call is forwarded,” it indicates your number is diverting calls.
- Frequent complaints from callers: If people say your number is always busy, unreachable, or never rings, it might mean calls are being forwarded without your knowledge.
- Manually check in settings: Navigate to the call forwarding section of your Phone app to review and disable any active rules.

Why should you activate call forwarding?
People activate call forwarding for various reasons. Here are some of the crucial reasons why you should activate call forwarding on your SIM card.
- Stay reachable when your phone is off or has no signal: Call forwarding ensures important calls reach you even if your phone is switched off, dead, or in a no-network zone. You can divert them to another working number, such as a secondary SIM or landline.
- Manage calls during busy periods: If you are on another call or in a meeting, you can forward incoming calls to an assistant, colleague, or voicemail. This helps you avoid missing calls while staying professional and organised.
- Avoid missing urgent calls when travelling: When travelling, especially to areas with poor reception or when using roaming, call forwarding can route your calls to a local number or someone you trust. It helps maintain communication without high roaming charges.
- Separate personal and work calls: You can direct business calls to a work phone during office hours and turn it off afterwards. This keeps personal and work life balanced and ensures better focus.
Call forwarding is a powerful feature that enhances your communication flexibility. Whether you want to stay accessible while travelling, manage calls during busy periods, or avoid missing important conversations, knowing how to activate or deactivate call forwarding gives you full control.
