How to block a number from calling you
If you block a person, they will not be able to call, text, or FaceTime you. Therefore, learn how to block a number on MTN, Glo, Airtel, or the 9mobile network to stop those pesky callers from disturbing your peace of mind.
1. How do you block someone from calling you on MTN?
You should learn how to block a number from calling you using a USSD code and the MTN blacklist code. It will help you to prevent annoying calls from ruining your day.
- Dial *35*0000*Nigerian phone number# (e.g. *35*0000*08123456789# ) and click SEND.
- Dial *35*0000# and click SEND to unblock all Nigerian phone numbers.
- Dial *351*international phone number# to block international numbers.
The advantage of blocking a number at the carrier level is that the blocked phone numbers cannot contact you if you change your phone or swap SIM cards. You can also use the code to block a number from calling, regardless of the network you or they are using.
Your network might charge you a small fee for this service. Additionally, the Calls and SMS blocking code may vary by network provider. Therefore, contact your network’s customer care agents for more inquiries about blocking terms, conditions, and fees.
How to block incoming calls on MTN Uganda
MTN Uganda subscribers use a different code from MTN Nigeria. Dial 21190#, then confirm with OK to block all incoming calls on your line.
When you want calls again, dial ##002# and confirm with OK to cancel the barring. Contact MTN Uganda’s customer care line if the code does not go through, since prompts occasionally change.

2. How to block calls on Glo
Glo users can block an individual caller through their phone’s contact or call settings. This is usually the most convenient option when you want to stop one particular person but continue receiving calls from everyone else.
Glo also supports call-barring functions. The standard GSM code reported for barring incoming calls is: *35*0000#. To remove incoming-call barring, use: #35*0000#
These codes are for incoming-call barring rather than blocking one specific contact. Glo’s own information confirms that its services can be affected when incoming calls are blocked.
3. How to block calls on Airtel
Airtel Nigeria provides call barring, which can restrict incoming and outgoing calls. The network’s official website says call barring is activated using a personal PIN 2 and advises customers to contact customer care for the code or assistance.
If you only want to block one person, use your phone’s built-in block feature instead. This allows you to keep receiving calls from other contacts.
Airtel also has a separate Do-Not-Disturb service for promotional messages. Customers can send STOP to 2442 to activate full DND. This is intended for promotional messages and should not be confused with blocking a particular caller.
4. How to block calls on 9mobile
9mobile users can block individual numbers through their phone’s call or contact settings. This is preferable if you want to prevent one particular person from calling while allowing other callers through.
Call barring is another option for restricting incoming calls generally. The standard GSM code commonly used for incoming-call barring is:*35*0000#
To deactivate it, dial: #35*0000#
If your barring PIN has been changed, use the current PIN instead of 0000. If the code fails, contact 9mobile customer support for assistance.

8. How to block a number from calling you on a button phone
Many basic or button phones do not have a call-settings menu for blocking. In that case, your best options are the network’s call-barring code above. The process varies by model, but you can generally try these steps:
- Open Contacts or Call Log.
- Select the number you want to block.
- Open Options.
- Look for Add to blacklist, Block number, Reject list or a similar option.

How to stop incoming calls without blocking using code?
You can stop incoming calls from a particular phone number without blocking using these options:
- Go to your smartphone’s settings.
- Tap on the Sound feature.
- Select the option Do Not Disturb.
- Click on the call.
- Select Do Not Allow Any Calls from the pop-up menu.
Please note that your phone might have a different procedure. You can also stop incoming calls by turning on your phone’s Aeroplane/Flight Mode or activating voicemail.
Instead of stopping incoming calls, use your network’s call diverting codes to allow forward calls to one of your other phone numbers or your network’s call waiting and holding codes to put calls on hold so you can receive a new incoming call or make a new outgoing call.
How to permanently block a number from calling you?
Blocking through your phone’s settings is permanent until you manually remove the number from your blocklist, so it stays in place even after a restart.
For a block that survives a lost phone or a SIM swap, pair it with your network’s call-barring service, since that sits on the network side rather than the handset. Review your blocklist occasionally, since phones rarely notify you when it grows long.
How to block your MTN SIM card online?
This is different from blocking a caller; it stops your entire line from working, which is useful if your phone is lost or stolen. Log in to the MyMTN app or the MTN self-service website, go to the security or SIM management section, and select the option to block or suspend your SIM.
You can also call MTN customer care on 180 from another line to request an immediate block while you arrange a replacement SIM.
What is the code to block a number from calling you?
There is no single universal USSD code that reliably blocks one specific caller across MTN, Glo, Airtel and 9mobile. The commonly used GSM code *35*PIN# bars incoming calls as a category. It does not function like the block button on an Android or iPhone.
If you want to stop only one number, use your handset’s blocking feature. If you want to stop all incoming calls, call barring may be appropriate.
How do you stop a particular number from calling you?
The easiest method is to block the number directly on your phone.
The best way to learn how to block a number from calling you is by familiarising yourself with all features on your phone. You should also contact your network’s customer care agents to learn more about their call and SMS blocking services.
