How to Enable or Disable Call Barring on iPhone & Android (Easy Guide)

Enabling or disabling call barring helps you control the types of calls you can make or receive on your phone. It lets you block outgoing calls, such as international calls, or restrict incoming calls when you do not want to be disturbed.
However, the process to enable or disable call barring on iPhone and Android is not always straightforward. The feature is often hidden within different menus, and in some cases, you may also need a password or an MMI code provided by your operator.
The good news is that turning call barring on or off does not have to be confusing. In this guide, you will learn exactly how to enable or disable call barring on both Android and iPhone devices step by step.
Key Highlights:
- Call barring helps you control which calls you can make or receive. It often involves blocking outgoing international calls or restricting incoming calls.
- Before turning on call barring, make sure your carrier supports it and ensure it doesn’t interfere with other calling features on your device.
- On Android phones, you can enable or disable call barring by dialing the MMI code or through the Phone app settings under Supplementary Services or Call Settings.
- iPhones have limited native support for call barring; you can use MMI codes or third-party apps like Truecaller to manage restrictions.
- To deactivate call barring, follow the same steps as activation, before entering your PIN to remove restrictions.
Things to Know Before Enabling Call Barring
Before enabling call barring, check if your carrier supports it and ensure you have the required PIN or password. Also, be aware that it may affect features like voicemail or call forwarding.
- Carrier Support: Some carriers may only allow you to block incoming or outgoing calls. So, it’s best to check with your carrier to see if they support international call barring.
- Password or PIN: Most phones ask for a PIN or password to turn call barring on or off. This code is usually set by your carrier, so you need to contact them to obtain it.
- Compatibility with Other Features: Enabling call barring options can interfere with the voicemail or call forwarding features in your device. It’s advisable to test or ask your carrier before turning it on.
