Call barring is a useful feature that allows mobile users to restrict certain types of calls on their phones, such as outgoing international calls, incoming calls when roaming, or all outgoing calls. However, there are times when you may need to disable this feature to resume normal calling functionality. One of the easiest ways to manage call barring is through a USSD code. USSD codes are quick commands entered directly into your phone’s dialer to communicate with your mobile network operator. Using the correct USSD code to cancel call barring ensures that your phone can make and receive calls without restrictions.
Understanding Call Barring
Call barring is a network service provided by mobile operators that lets users control which types of calls are allowed or blocked on their phone. It is particularly useful for preventing unauthorized usage, controlling costs, or restricting certain types of communication for personal or business reasons. Call barring can be applied to outgoing calls, incoming calls, international calls, or calls when roaming.
Types of Call Barring
- Outgoing Call Barring – prevents all outgoing calls or specific types like international calls.
- Incoming Call Barring – blocks all incoming calls or calls while roaming.
- International Call Barring – restricts international outgoing calls to control expenses.
- All Calls Barring – blocks both incoming and outgoing calls for total call restriction.
Understanding the type of call barring activated on your phone is important because the USSD code used to cancel it can vary depending on the specific restriction.
What Is a USSD Code?
USSD stands for Unstructured Supplementary Service Data, which is a protocol used by GSM cellular phones to communicate with the mobile network operator. USSD codes are short codes that typically begin with an asterisk () and end with a hash (#). These codes allow users to check balances, activate services, or modify settings directly with the network, without needing an app or internet connection.
Why USSD Codes Are Useful for Call Barring
- Quick and easy to use without internet access.
- Works across most GSM and 4G networks.
- Provides immediate confirmation from the network.
- Allows precise control over specific network services, such as call barring.
Because USSD codes communicate directly with the network, they are an effective method to cancel call barring instantly.
How to Cancel Call Barring Using USSD Codes
The process to cancel call barring using a USSD code generally involves dialing a specific code followed by your phone’s barring password or PIN. Most mobile networks require a default password for call barring, often set to 0000, unless changed by the user.
Steps to Cancel Call Barring
- Open your phone’s dialer application.
- Identify the type of call barring you want to cancel (outgoing, incoming, international, or all calls).
- Enter the USSD code for cancelling the specific type of call barring.
- Enter your barring password when prompted.
- Wait for confirmation that the call barring has been successfully deactivated.
It is important to use the correct code for the type of call barring you want to cancel, as different restrictions require different codes.
Common USSD Codes to Cancel Call Barring
While USSD codes may vary slightly between operators, the following codes are generally used to cancel different types of call barring
Outgoing Call Barring
- 33password# – Cancels all outgoing call barring.
- 331password# – Cancels barring of international outgoing calls only.
Incoming Call Barring
- 35password# – Cancels all incoming call barring.
- 351password# – Cancels barring for incoming calls while roaming.
All Calls Barring

Remember to replacepassword with your actual barring PIN, which is typically provided by your mobile operator.
Tips for Using USSD Codes Effectively
Using USSD codes is straightforward, but a few tips can help you avoid errors and ensure that call barring is successfully canceled.
Best Practices
- Verify your current barring status before using a USSD code to avoid unnecessary commands.
- Always use the correct password; multiple wrong attempts may temporarily lock the barring feature.
- Keep your barring password secure and change it from the default if needed.
- Confirm the cancellation with a test call to ensure your outgoing and incoming calls work correctly.
- Contact your mobile operator if the USSD code does not work, as some networks have unique codes.
Following these best practices helps ensure that your call barring settings are properly managed and that you maintain control over your phone usage.
