How to Forward Calls on iPhone with any Carrier: Explore Complete Details

Call forwarding on your iPhone can be a lifesaver in situations where you can’t afford to miss important calls, whether you’re in a meeting, on vacation, or experiencing phone issues. This feature ensures that you remain reachable by routing your incoming calls to another number. This guide provides a comprehensive overview of how to activate call forwarding on your iPhone across various carriers.

Understanding Call Forwarding

Before diving into the specifics, it’s essential to understand what call forwarding is and how it can be useful. Call forwarding, also known as call diversion, allows incoming calls to be redirected to a different number. This can be another mobile phone, a landline, or even a VoIP service, depending on your needs and setup.

How to Set Up Call Forwarding on iPhone

The process to enable call forwarding might slightly vary depending on your carrier, but the basic steps are generally the same across GSM networks such as AT&T, T-Mobile, and internationally.

Steps to Enable Call Forwarding:

  1. Open Settings: Start by tapping the Settings icon on your iPhone.
  2. Navigate to Phone Settings: Scroll down and select “Phone” from the list of options.
  3. Access Call Forwarding: Tap on “Call Forwarding” within the phone settings.
  4. Activate Call Forwarding: Toggle the “Call Forwarding” switch to ON.
  5. Enter the Forwarding Number: In the “Forward To” field, input the phone number where you want your calls redirected.
  6. Confirm Settings: Press the back button to save and activate the call forwarding settings.

It’s important to note that while these steps apply to most GSM networks, the availability and specific process might differ slightly with your carrier.

Using Forwarding Codes for Older Networks and Specific Carriers

For users on CDMA networks such as Verizon or legacy networks like Sprint, enabling call forwarding through iPhone settings might not be an option. Instead, you’ll need to use specific USSD codes provided by the carrier.

Common Forwarding Codes:

  • T-Mobile: Dial 21* followed by the 10-digit phone number, and # to forward all calls. To deactivate, dial ##21#.
  • Sprint (now part of T-Mobile): For legacy Sprint users, activate by dialing *72 followed by the number. Deactivate with *720.
  • Verizon: Enable by dialing *72 followed by the number. To turn off forwarding, dial *73.

These codes allow you to set up call forwarding directly through the network, bypassing the need for in-phone settings.

Advanced Forwarding Options: Conditional Call Forwarding

Beyond basic call forwarding, most carriers also offer conditional call forwarding, which is used when you want to forward calls only under specific conditions, such as when your phone is busy, when you don’t answer, or when you’re unreachable.

How to Set Up Conditional Forwarding:

  • Unanswered Calls: Typically involves dialing a code like *61* followed by the forwarding number and #.
  • When Busy: Use a code like *67* followed by the forwarding number and #.
  • When Unreachable: Dial *62* followed by the forwarding number and #.

These options ensure that you can maintain control over how and when your calls are forwarded, making the feature suitable for varying personal and professional needs.

Troubleshooting Common Issues

Sometimes, you might encounter issues where call forwarding isn’t working as expected. Here are a few troubleshooting tips:

  • Verify Activation: Double-check if the call forwarding is correctly set up and activated in your iPhone settings or using the correct USSD code.
  • Check Number Format: Ensure that the forwarding number is entered correctly, including area codes.
  • Carrier Limitations: Some carriers may not support forwarding to international numbers or might have specific restrictions. Check with your carrier for details.


Call forwarding is an invaluable feature for anyone who needs to ensure they’re always reachable, regardless of circumstances. By following the appropriate steps for your carrier and understanding how to use the various codes and settings, you can effectively manage your incoming calls and stay connected wherever you are.
