Are you tired of missed calls being automatically forwarded to voicemail, another number, or a mysterious third party? In the current digital landscape (December 2025), controlling your incoming calls is a critical aspect of mobile security and privacy. Call diversion, also known as call forwarding, is a helpful feature when used intentionally, but if left active by accident—or worse, maliciously—it can cause you to miss crucial communications and potentially expose your number to unwanted services. This comprehensive, up-to-date guide provides you with the universal USSD codes and the exact, step-by-step device settings you need to permanently disable all types of call forwarding on any smartphone or network.

Stopping call divert is far simpler than you might think, often requiring nothing more than dialing a quick, universal code. Forget digging through confusing menus; the most effective and fastest method is using a short code that overrides all your phone’s settings and communicates directly with your mobile network's switching center. We'll show you the master code that works almost everywhere, plus the specific codes to target individual forwarding types.

The Master Keys: Universal USSD Codes to Deactivate All Call Forwarding

The fastest and most reliable way to disable any form of call forwarding is by using a universal USSD (Unstructured Supplementary Service Data) code. These codes are standardized across most GSM (Global System for Mobile Communications) networks worldwide, including major carriers like T-Mobile, Vodafone, Telkomsel, and many others. Always dial these codes from your phone’s keypad and press the call button.

The two most powerful codes you need to know are the "Erasure Codes," designed to wipe out all active forwarding settings.

  • ##002# (The Universal Master Code): This is the ultimate code to cancel all active call forwarding/diverting services on your line, regardless of the type (unconditional, busy, no answer, or unreachable). It’s the first and best code to try for an instant fix.
  • ##004# (The Conditional Master Code): This code is specifically designed to cancel all conditional call forwarding. Conditional forwarding includes situations where your phone is busy, you don't answer, or your phone is unreachable. If ##002# doesn't work, this is your next best option.

Check Your Call Forwarding Status First

Before deactivating, you can check which forwarding services are currently active on your number. This is a crucial step for troubleshooting and security.

  • *#21# (Check All Forwarding Status): Dial this code to see if your calls, SMS, or data are being unconditionally forwarded and to which number.
  • *#61# (Check 'No Answer' Forwarding Status): This shows the status of forwarding when you don't answer a call, and the number the call is being forwarded to.
  • *#67# (Check 'Busy' Forwarding Status): Use this to check the status of forwarding when your line is busy.

Targeted Deactivation: Stopping Specific Types of Call Divert

Call forwarding is categorized into four main types. If you only want to stop one specific type of call diversion (e.g., you want to keep voicemail for "no answer" but stop "unconditional" forwarding), you can use these targeted deactivation codes.

These codes follow the format ##[Code]# and are universally recognized on GSM networks.

1. Unconditional Call Forwarding (Always Forward)

This is the most intrusive type, as all calls are immediately diverted without your phone ever ringing. It’s often the setting used in call-forwarding scams.

  • Deactivation Code: ##21#

2. Call Forwarding When No Reply/No Answer

This is the most common setting, typically diverting to your voicemail after a set number of rings (usually 15-30 seconds). If you want your phone to ring indefinitely, you must disable this.

  • Deactivation Code: ##61#

3. Call Forwarding When Busy

This setting diverts calls when you are already on the line. Disabling it means a caller will receive a busy signal instead of being diverted.

  • Deactivation Code: ##67#

4. Call Forwarding When Unreachable/Out of Service

This diverts calls when your phone is turned off or you are out of network coverage. Disabling it means callers will hear a "number unreachable" message instead of being diverted to a number.

  • Deactivation Code: ##62#

Device Settings: How to Disable Call Forwarding on iPhone and Android

While the USSD codes are the fastest method, you can also manage and disable call forwarding directly through your smartphone's settings. This is often necessary if the USSD codes do not work due to specific carrier restrictions or if you prefer a visual interface.

For Apple iPhone Users (iOS)

The process is straightforward as Apple keeps the Call Forwarding toggle easily accessible within the Phone settings.

  1. Open the Settings app on your iPhone.
  2. Scroll down and tap on Phone.
  3. Tap on Call Forwarding.
  4. Wait a moment for the current status to load.
  5. Toggle the Call Forwarding switch to the OFF position (white/grey). If it was ON, you will see the number your calls were being diverted to.

For Google Android Users

The menu path can vary slightly depending on your phone's manufacturer (Samsung, Google Pixel, OnePlus) and the Android version, but the core settings are found within the Dialer or Phone app.

  1. Open the Phone (Dialer) app.
  2. Tap the three-dot menu (⋮) or More icon, usually in the top right corner.
  3. Tap Settings or Call Settings.
  4. Look for the Calling Accounts or Supplementary Services option, then tap on Call Forwarding.
  5. You will see a list of the four forwarding types: Always forward, Forward when busy, Forward when unanswered, and Forward when unreachable.
  6. Tap on each option that shows an active number and select Turn Off or Disable.

Carrier-Specific Deactivation Codes (US & Global Examples)

Although the universal GSM codes (`##002#`) work for most carriers, some networks, particularly in the US, use their own proprietary codes for certain services.

  • Verizon Wireless: To disable all call forwarding, dial *73 and press the Call button.
  • AT&T Wireless: To disable all call forwarding, dial *73#.
  • T-Mobile (US): The universal codes like ##21# for unconditional forwarding are generally recommended, but the master code ##002# should also work.
  • Vodafone (Global): Vodafone UK specifically recommends dialing ##002# to cancel all diverts.

Troubleshooting: Why Call Forwarding Might Revert or Not Stop

If you've dialed the universal codes and checked your phone settings, but call diversion keeps reactivating or you're unable to disable it, consider these advanced troubleshooting steps:

  • Check for a Conflicting App: Third-party apps that offer voicemail, call screening, or virtual number services (like Google Voice, Skype, or business VoIP apps) often use call forwarding to route calls. Disabling the feature within the third-party app itself is necessary to stop the divert.
  • Verify with Your Carrier: Sometimes, call forwarding is a network-level feature provisioned on your account, not just on your device. Contact your carrier's customer support (e.g., Verizon Customer Support, T-Mobile Support) and ask them to "de-provision" or "remove the call forwarding feature" from your account entirely.
  • Ensure Conditional Codes are Used: If your calls are only diverted when you don't answer, the unconditional code (##21#) won't work. You must use the conditional code ##004# or the specific ##61#.
  • SIM Card Issue: If you recently moved your SIM card to a new phone, the old phone's settings might have left a residual forwarding instruction on the network. Using ##002# will clear this network instruction.

By using the universal erasure code ##002#, or by navigating directly to your device's Call Forwarding settings, you can ensure that you have complete control over your incoming calls, protecting your privacy and ensuring you never miss another important communication.
