Mastering Connectivity: The Ultimate Guide to Call Forwarding on iPhone
In an era of constant connectivity, the ability to manage your incoming communications is vital. Whether you are traveling abroad, managing a business, or simply trying to preserve your battery life, knowing how to forward calls on iPhone is a fundamental skill for every user.
From the classic iPhone 11 to the cutting-edge iPhone 15 and even looking ahead toward the anticipated capabilities of the iPhone 17, the core mechanics of call redirection remain a cornerstone of iOS functionality. This guide provides an exhaustive deep dive into setting up forwarding, troubleshooting recent iOS 18 glitches, and managing carrier-specific requirements like those found on Verizon.
Step-by-Step: How to Forward Calls on iPhone (All Models)
Regardless of whether you are using an iPhone 11, 13, or 14, the process for setting up call forwarding via the iOS interface remains remarkably consistent. Apple has streamlined this feature to ensure that users can redirect their calls in just a few taps.
The Standard Settings Method
To forward your calls to another number or phone, follow these precise steps:
- Open the Settings App: Locate the gear icon on your Springboard.
- Navigate to Phone: Scroll down until you find the ‘Phone’ module.
- Select Call Forwarding: Tap on the ‘Call Forwarding’ option.
- Toggle On: Switch the toggle button to the ‘On’ position (it will turn green).
- Enter the Destination: Tap ‘Forward To’ and type in the full phone number you wish to receive your calls.
- Verify: Once entered, tap ‘Back’ to save the settings.
How to Forward Calls on iPhone 15 and iPhone 16
With the latest hardware iterations like the iPhone 15 and iPhone 16, users often look for more advanced integration. While the basic steps remain identical, these newer models benefit from enhanced cellular modem stability, making the handoff between your device and the forwarded number much smoother during high-traffic periods.
Future-Proofing: How to Forward Calls on iPhone 17
While the iPhone 17 is still on the horizon, we can anticipate that Apple will continue to refine the ‘Call Forwarding’ UI. Based on current trajectories in iOS development, users should expect even tighter integration with Apple Intelligence, potentially allowing for-voice command-based forwarding (e.g., “Siri, forward my calls to my office number while I’m driving”).
Specific Scenarios: Redirecting to Other Numbers and Voicemail
Users often have different goals when managing their incoming traffic. We have categorized the most common requests below.
How to Forward Calls on iPhone to Another Number or Phone
If you are transitioning between work and personal life, you may need to forward calls on iPhone to another phone entirely (such as an iPad with a cellular connection or a secondary device). The process is the same: input the target digits in the ‘Forward To’ field. This ensures that no matter which physical device you have on hand, your important communications follow you.
How to Forward Calls on iPhone to Voicemail
There are times when you don’t want a person answering; you simply want the call to go straight to your digital receptionist. To forward calls on iPhone to voicemail, you can either:
- Use Carrier Codes: (See the section below).
- Set ‘Do Not Disturb’: While not technically forwarding, enabling Focus modes effectively pushes all incoming calls directly to your voicemail without the phone ringing.
\ Note: This is ideal for deep-work sessions or during sleep.
Carrier-Specific Instructions: Verizon and Major Networks
Sometimes, the iOS settings menu might not reflect the changes immediately due to carrier overrides. If you are using how to forward calls on iPhone Verizon or other major US carriers (AT&T, T-Mobile), you may need to use MMI/USSD codes—essentially ‘secret’ dialer commands.
| Method | Action/Code | Use Case |
| iOS Settings | Toggle in Phone App | Standard redirection for most users |
| Verizon/AT&T Code | `21 [Number] #` | Immediate activation via network signal |
| Deactivation Code | `##21#` | To stop all forwarding and return to normal |
| Check Status | `*#21#` | To see if a number is currently being forwarded |
Pro Tip: If the Settings menu fails, dialing `21[TargetNumber]#` and pressing call is often more reliable for carriers like Verizon as it instructs the network directly rather than relying on the device software.
Troubleshooting: What to do if Call Forwarding is Not Working on iOS 18
Recent reports from tech observers indicate that some users are experiencing issues where Call Forwarding is not working on iOS 18. If your calls are still ringing on your primary device despite having the toggle ‘On’, follow this troubleshooting checklist:
1. Reset Network Settings
This is the most effective way to clear glitches in how your iPhone communicates with cellular towers.
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
Warning: This will also erase saved Wi-Fi passwords.*
2. Check Carrier Settings Update
Sometimes, a carrier update is required to support new iOS features. Go to Settings > General > About. If an update is available, a prompt will appear automatically.
3. Verify Cellular Data and Signal
Call forwarding requires a stable handshake with the network. If you are in a low-signal area, the instruction to forward might not reach the carrier’s switching center.
Advanced Tips: Battery Management and Hidden Features
Set Up Call Forwarding When Your Phone Battery Is Dying
One of the most overlooked use cases is emergency management. As your phone battery is dying, you should proactively set up call forwarding to a landline or a partner’s phone. This ensures that even when your iPhone shuts down, your incoming calls are not lost in a vacuum but are redirected to an active device.
Using Secret Phone Codes for Hidden Features
As noted by industry experts, there are several secret phone codes that can unlock hidden diagnostic features on both Android and iPhone. While primarily used by technicians, using `#06#` to check your IMEI or `#31#` to hide your caller ID can be part of a larger strategy for managing your device’s identity and connectivity.
Summary Table: Quick Reference Guide
| Feature | Primary Method | Best For |

| Carrier Forwarding | Dial Codes (`21`) | Verizon/AT&T users, bypassing software bugs |
| Voicemail Redirect | Do Not Disturb / Carrier Code | Privacy and uninterrupted sleep |
| Emergency Setup | Manual redirection before shutdown | Battery preservation |
