title：How to Disable Call Forwarding: Easy USSD Codes Guide

content：Stop Unwanted Call Forwarding in Minutes

Have you ever noticed calls to your number going to someone else without your knowledge? Maybe a friend pranked you, or you forgot to turn off forwarding after a trip. Either way, it’s frustrating. This guide breaks down the exact steps to check and disable call forwarding using quick USSD codes—no complex settings needed.

After analyzing the video, I’ve simplified the process into actionable steps that work for most GSM networks (like Airtel, Jio, and Vodafone). Let’s dive in.

What Is Call Forwarding & Why It Matters

Call forwarding redirects incoming calls from your number to another. It’s useful for travel or busy days, but unauthorized forwarding can compromise your privacy. The video emphasizes that checking and disabling it is critical to keep your calls secure.

GSM networks (used by most mobile carriers globally) rely on USSD codes for quick service access. These codes are universal and work even if your phone’s settings menu is hard to navigate.

Step 1: Check If Call Forwarding Is Active

First, confirm if your calls are being forwarded. Here’s how:

1. Open your phone’s dialer app.
2. Dial *#21# and press the call button.
3. Wait for the screen to display details: it will show if forwarding is active and the number your calls are going to.

Pro tip: Note down the forwarded number if you see one—this helps you confirm later that it’s disabled.

Step 2: Disable Call Forwarding Instantly

Once you’ve verified forwarding is active, turn it off with this code:

1. In your dialer, dial ##21# and press call.
2. You’ll get a confirmation message: “Call Forwarding Unconditional Service Has Been Disabled.”

Important: Always verify by calling your number from another device to ensure calls now ring on your phone.

Alternative Methods for Non-USSD Users

If you prefer graphical settings over codes:

• For Android: Go to Phone > Settings > Calls > Call Forwarding and toggle off all options.
• For iOS: Go to Settings > Phone > Call Forwarding and switch it off.

USSD codes are faster, but these settings work if you want more control over specific forwarding types (like busy or no answer).

Security Alert: Unauthorized Forwarding

If you find forwarding active without your consent:

1. Disable it immediately using the ##21# code.
2. Change your SIM PIN to prevent someone from accessing your network settings.
3. Contact your carrier to report any suspicious activity.

This extra step keeps your number safe from misuse.
