I have a confession to make. I once missed a job offer because my phone was silent. Not dead. Not broken. Just... silent. The call went straight to voicemail while I sat there refreshing my email like an idiot. Turns out, I had accidentally enabled a feature I didn't understand. That feature was call forwarding. And it had been rerouting my calls to an old burner phone I'd tossed in a drawer months earlier.
Let me save you from that same gut-punch feeling. Here's everything you need to know about call forwarding iphone—the good, the bad, and the "why did Apple put this setting HERE?"
What Exactly Is Call Forwarding? (And Why You Should Care)
Call forwarding is a feature that reroutes incoming calls from your iPhone to another number. Simple concept. Massive implications.
Think of it like mail forwarding. You move houses, but letters still need to reach you. Your phone number is your digital address. When you enable call forwarding, every call that comes to your iPhone gets redirected elsewhere. A landline. Another mobile. Your grandma's flip phone. Whatever number you choose.
I use it constantly. Here's why you might too:
- You travel for work. International roaming charges are a scam. Forward your US number to a local SIM and save your wallet.
- Your battery dies at 2 PM. Happens to me weekly. Forward calls to your tablet or a coworker's phone.
- You're avoiding someone. Not blocking them, just... redirecting. We've all been there. No shame.
- You work from home but need a professional landline. Forward your work number to your iPhone and answer from anywhere.
- You're at a concert, festival, or anything with terrible reception. Forward to a friend's phone and enjoy the show.
I once forwarded my phone to my sister during a camping trip. She got a call from my dentist about a cleaning appointment. She handled it. I got a text later: "Your teeth are fine. You owe me coffee."
Context is everything.

The Carrier Reality Check Nobody Warns You About
Here's the dirty secret about call forwarding iphone: it's not entirely up to Apple. Your carrier holds some of the cards. AT&T. Verizon. T-Mobile. They all handle it differently.
I learned this the hard way. I was on a prepaid plan years ago. I spent twenty minutes digging through Settings, toggling switches, feeling like a tech genius. Nothing worked. Calls still rang on my iPhone. I called support. The rep said, nice as could be, "Sir, your plan doesn't support call forwarding."
I wanted to throw my phone into a river.
So before you do anything else, check these two things:
First, does your plan allow forwarding? Prepaid plans often block it. Some budget carriers charge extra. Log into your account online or call your carrier. Ask specifically about "unconditional call forwarding." That's the industry term. Use it. Sound smart.
Second, does your carrier support conditional forwarding? This means forwarding only happens when your line is busy, unanswered, or unreachable. Most carriers support it. But not all. And the ones that do might use weird codes to activate it.
I still get annoyed thinking about it. It's 2026. We have self-driving cars and AI that writes poetry. But I still need to call a customer service line and press 2 for "technical support" just to forward a phone call. Progress.
The Step-by-Step Setup You've Been Waiting For
Okay. Let's do this. I'm holding my iPhone right now. You should be holding yours too.
The native method works on iOS 15 through the latest version. Apple hasn't moved these menus much. Probably because they forgot they exist.
Open Settings
Tap the gear icon. It's gray. You know the one.
Scroll Down to Phone
This is where most people get lost. You need to keep scrolling. Past Bluetooth. Past Notifications. Past the Apple ID stuff you never touch. Keep going until you see "Phone." It's usually between "Music" and "Photos." Tap it.
Find Call Forwarding
Under the "Calls" section, you'll see it. Right below "Silence Unknown Callers." Right above "Change Voicemail Password." It's hiding in plain sight.
Flip the Toggle
You'll see a switch at the top that says "Call Forwarding." Flip it green. Your iPhone will pause for a second. It's contacting your carrier. If it fails, you know who to blame.
Enter the Forwarding Number
A new field appears: "Forward To." Tap it. Type the number you want calls sent to. Use full international format if needed. +1 for US numbers. +44 for UK. Don't forget the plus sign. I typed 1-555... once and my calls vanished into the ether. Never again.
Test It
Call your iPhone from another phone. If it rings on the forwarded number, you win. If it doesn't, check your carrier settings. Or curse quietly to yourself.
That's it. You've successfully set up call forwarding iphone to another number. Took two minutes. Feels good, right?
How to Set Up Call Forwarding iPhone to Another Phone (Real Scenarios)
The basic method works for any number. But life isn't basic. Let's get specific.
Forwarding to a Landline
Landlines are the vinyl records of phones. They're making a comeback. Sort of. If you need to forward to a landline, enter the number with the area code. Example: 212-555-1234. Country code if you're dialing internationally. Calls usually redirect within a ring or two. No extra steps needed.
I forwarded my iPhone to a landline once. At a cabin. No cell service. It worked perfectly. I felt like a wilderness survival expert. Then the landline rang at 3 AM. Spam call. So much for escaping civilization.
Forwarding to Another Mobile Number
This is the most common scenario. You have a work phone and a personal phone. You want work calls to hit your personal phone while you're on vacation. Or vice versa.
Enter the work number in the "Forward To" field. Done. But here's the trick: turn off call waiting on the receiving phone. Otherwise you'll get double audio. Echoes. Feedback. It sounds like a nightmare, and it is.
Forwarding to an International Number
Traveling abroad? You can forward your US number to a UK SIM. Enter +44 followed by the local number. Drop the leading zero from the local number. Example: +44 20 1234 5678.
But watch out. Carriers charge for international forwarding. Even if you don't answer the call. I once forwarded to a French number for a weekend. My bill had a $50 "international forwarding surcharge." I almost cried. Check your plan first.
Conditional Forwarding (When You Don't Answer)
What if you only want forwarding when you're busy or unreachable? That's conditional forwarding. It kicks in when your phone is off, busy, or unanswered.
Apple's native iPhone settings don't let you configure this directly. Annoying, right? You'll need carrier codes instead.
Here are the common US carrier codes:
Verizon: Dial *72 followed by the forwarding number, then press Call. To stop, dial *73.
AT&T: Dial **21* plus the number plus # then call. Disable with ##21#.
T-Mobile: Dial *21* plus the number plus # then call. Cancel with ##21#.
Want only unanswered calls forwarded? Use *61* instead. This is where it gets nerdy. But it works. I keep these codes saved in my Notes app. You should too.
How to Call Forwarding iPhone Turn Off
Eventually, you'll want to stop the madness. Maybe you're back home. Maybe you're tired of your mom answering your work calls. (She means well. But clients don't need to hear about her cat's diet.)
Turning it off is easier than turning it on.
Method 1: Settings (The Easy Way)
Open Settings. Go to Phone. Tap Call Forwarding. Flip the toggle to OFF. Gray. Done. Your iPhone will disconnect from the carrier's forwarding feature. You might see a spinning wheel. That's normal. You're free.
Method 2: Carrier Codes (The Nerdy Way)
Use the same codes from earlier but with different numbers. Dial ##21# on most carriers to disable all forwarding. Your phone might show a message: "Call Forwarding Deactivated." Feels satisfying every time.
Method 3: Carrier App (Why Would You)
Some carriers let you disable forwarding through their app. I've only done this once. It took three menus deep. I gave up and used Settings instead. Faster.
What Happens When You Turn It Off?
Incoming calls go straight to your iPhone again. Voicemail resumes normally. No more random calls showing up on another device. It's like putting a "Now Serving" sign back on your phone. Peace restored.
I once forgot to turn off forwarding after a weekend trip. My mom's phone got my work calls for two full days. She loved it. She felt important. My boss? Not so much. He called me Monday morning asking why I sounded like a 65-year-old woman named Brenda. I explained. He didn't laugh.
Troubleshooting Call Forwarding Issues
Call forwarding isn't perfect. Here are the problems I've encountered. And how to fix them without throwing your phone.
"Call Forwarding Failed" Error
This usually means your carrier is blocking it. Try restarting your phone. Toggle Airplane Mode on and off. If that fails, call your carrier. Ask them to enable "unconditional forwarding" on your account. Use those exact words. Sound confident.
I once had to argue with a chatbot for ten minutes. It kept saying "I'm sorry, I don't understand." I wanted to scream. Finally I typed "SPEAK TO A HUMAN" and it transferred me. Victory.
Forwarding Only Works Sometimes
You might have conditional forwarding enabled without knowing it. Check your carrier's settings via the phone dialer. Dial *#21# to see what's active. If it shows "Call Forwarding: Active," you're fine. If it shows "Unconditional," all calls are going there.
Calls Still Ring on Original Phone
This happens when your carrier doesn't fully support the feature. Some prepaid carriers forward calls but still let the original phone ring once. That's a carrier limitation. Not an iPhone problem. You can't fix it without switching plans.
Forwarding Number Wrong
Double-check the number you entered. Miss a digit? It won't work. Also, make sure you're not using spaces or dashes. Just plain numbers with a plus sign if it's international. I once forgot the plus sign before an international number. Calls went nowhere. I felt like an idiot.
Carrier Codes Aren't Working
Make sure you're dialing from the iPhone itself. Not from a third-party app. Also, some carriers require you to be on their network. Not Wi-Fi calling. Try turning off Wi-Fi and dialing again.
My Personal Relationship with Call Forwarding
I have a love-hate relationship with this feature. I'll be honest.
I love it when I'm traveling. I forward my US number to a local SIM and save money. I love it when I'm working from a coffee shop with terrible reception. Forward to my Google Voice number. Problem solved.
But I hate it when I forget to turn it off. I hate it when my carrier charges me extra. I hate it when I try to explain it to my parents and they look at me like I'm speaking ancient Greek.
There was one time I forwarded my phone to a friend's number during a flight. I was testing something. The flight landed. I forgot to turn it off. My friend got a call from my bank about a fraudulent charge. He answered. He pretended to be me. The bank believed him. They blocked the charge. My friend saved me $200.
I owe him coffee forever.
Third-Party Apps vs. Native Settings
Sometimes the native iPhone method isn't enough. That's when third-party apps shine.
Here's a comparison based on my experience:
| Feature | Native iPhone | Third-Party (Google Voice, YouMail) |
|---|---|---|
| Cost | Free | Free (with limits) or paid upgrades |
| Setup Time | 2 minutes | 5-10 minutes (install + configure) |
| Conditional Forwarding | Limited (via codes) | Full control |
| Number Masking | No | Yes |
| Reliability | Carrier-dependent | App-dependent |
| Voicemail Transcription | No | Yes |
For most people, native is enough. But if you're a freelancer or business owner juggling multiple numbers, apps like Google Voice let you forward calls to multiple devices simultaneously. They also transcribe voicemails. That's neat.
I use Google Voice for my side hustle. It saves me from giving out my real number to strangers. Also filters spam calls. Worth the setup time.
When Call Forwarding Is a Bad Idea
Not every situation calls for it. Here's when you should avoid it:
- During an emergency. Emergency services don't always forward correctly. Dial 911 directly.
- If your carrier charges per minute. Some older plans do. Check your bill.
- If you're forwarding to a premium number. That's just sketchy. Don't.
- If you're already using VoIP. Double-forwarding confuses the network. Calls get lost.
Also, don't use it to prank someone. Forwarding your phone to your friend's number at 3 AM is funny for five minutes. After that, you're just a nightmare.
Trend Alert: Call Forwarding in 2026
Call forwarding feels like an old feature. But it's evolving.
With the rise of remote work, more people forward office phones to personal ones. With eSIMs becoming standard, travelers forward easily between carriers. With AI voicemail assistants, calls get forwarded to bots that handle screening.
I've noticed more people using call forwarding for privacy. They give out a Google Voice number. Then forward it to their real iPhone. Spam calls hit the Google number. Real calls hit their personal phone. Smart.
There's also a trend of "conditional forwarding only." People don't want all calls forwarded. Just the ones they miss. Carrier codes make this easy. But most users don't know they exist.
I think Apple should simplify conditional forwarding in iOS. But that's a pipe dream. For now, we have carrier codes and workarounds.
Final Thoughts
Setting up call forwarding iphone isn't rocket science. It's more like assembling IKEA furniture without the manual. You'll hit a wall occasionally. But once it's working, it's oddly satisfying.
Whether you're forwarding calls to a landline for work, a second phone for travel, or just avoiding spam, the feature is a lifesaver. When it works. And when your carrier doesn't charge you extra.
Remember the key steps: Settings > Phone > Call Forwarding. Toggle it on. Add the number. Test it. To turn it off, flip the toggle back.
Now go set it up. Forward your phone to a friend while you take a nap. They'll handle your calls. Probably. And if they don't? Well, that's what voicemail is for.
