Your Phone Rings, But You’re Not There to Answer
You’re in an important meeting, your hands are full with groceries, or you’re simply stepping out for a moment. That crucial call from your doctor’s office, your child’s school, or a client starts buzzing in your pocket, and you can’t pick up. The frustration of missed connections is a modern headache we all know too well.
AT&T’s call forwarding feature is the simple solution hiding in plain sight on your device. It automatically redirects incoming calls to another number of your choosing, ensuring you never miss a beat, whether you’re switching phones temporarily, traveling, or just need a digital receptionist for a few hours.
This guide will walk you through every method to set up call forwarding on AT&T, from quick dialer codes to detailed app settings. We’ll also cover how to turn it off, troubleshoot common issues, and explore the smart alternatives AT&T offers to keep you connected.
What Call Forwarding on AT&T Actually Does
Call forwarding, sometimes called call diverting, is a network feature, not just a phone setting. When you activate it, you instruct the AT&T network to reroute calls destined for your number before your phone even has a chance to ring. The caller hears the standard ringtones, unaware their call is being redirected behind the scenes.
There are several types of forwarding, each useful for different scenarios:
– Unconditional Forwarding: All calls are immediately sent to another number, no matter what.
– Busy Forwarding: Calls go to another number only when your line is busy.
– No Answer/Unavailable Forwarding: If you don’t pick up after a certain number of rings (usually 4 or 5), the call forwards.
– Not Reachable Forwarding: Forwards calls when your phone is off or out of network coverage.
For most everyday needs, unconditional forwarding (“Forward all calls”) is what you’ll use. The other types are powerful tools for creating a seamless call flow, like ensuring busy calls go to a voicemail service or a colleague.
Prerequisites and What to Check First
Before you start, confirm a few things. First, ensure your AT&T line is active and in good standing. Call forwarding is a standard feature included with all postpaid and most prepaid plans at no extra monthly cost, though forwarded calls may use your plan’s minutes.
You will need the target phone number you want to forward calls to. This can be a landline, another mobile number (even on a different carrier), or a voicemail service number. Also, have your phone handy. While you can manage some features online, the fastest methods use your phone’s dialer.
The Universal Method: Quick Dialer Codes
The fastest way to activate call forwarding is using star codes, also known as feature codes or vertical service codes. You enter these directly into your phone’s keypad as if making a call. They work on almost any phone, from the latest iPhone to a basic flip phone.
To forward all your calls immediately, open your phone app and dial exactly:
*21*[TargetPhoneNumber]#
Replace “[TargetPhoneNumber]” with the full 10-digit number, including area code. For example, to forward to 555-123-4567, you would dial: *21*5551234567# and then press the call button.
You will hear a confirmation tone or message, and see a notification like “Call Forwarding Activated” on your screen. Your phone will now not ring for incoming calls; they will go directly to the number you specified.
To deactivate forwarding and return to normal, simply dial:
#21#
Press call. You’ll get a confirmation that call forwarding is deactivated.
Other Useful AT&T Forwarding Codes
For more granular control, use these codes. Always dial them and press the call button.
– Forward when busy: *67*[TargetNumber]# to activate. #67# to deactivate.
– Forward when no answer: *61*[TargetNumber]# to activate. #61# to deactivate.
– Forward when unreachable: *62*[TargetNumber]# to activate. #62# to deactivate.
To check the status of any forwarding setting, dial *#21#, *#67#, *#61#, or *#62# respectively. A voice announcement or on-screen message will tell you the current forwarding destination.
Managing Forwarding Through Your Phone’s Settings
If you prefer a menu-driven approach, both iPhone and Android have call forwarding settings built in, though the path varies.
On iPhone (iOS)
Navigate to Settings > Phone. Scroll down and tap “Call Forwarding.” Toggle the switch on. You’ll then tap “Forward To” and enter the target phone number. This setting typically enables unconditional forwarding for all calls. Toggle the switch off to disable it.
A key point: this iPhone setting communicates with the AT&T network to enable the forwarding. If you have network issues, it may fail, in which case the dialer codes are a more reliable fallback.
On Android Devices
The path can differ by manufacturer (Samsung, Google Pixel, etc.), but the setting is usually in the Phone app itself. Open your Phone app, tap the three-dot menu or “More” settings, then look for “Settings” or “Call settings.”
Find “Call forwarding,” “Supplementary services,” or “Advanced settings.” You should see options for different forwarding types (Always forward, When busy, etc.). Tap the desired one and enter the number. Like on iPhone, this interfaces with the network to activate the feature.
Using the myAT&T App and Online Account
For account-wide management, the myAT&T app or website is a powerful tool. Log in to your account, either on the app or at att.com. Navigate to the section for managing your wireless line or device.
Look for options labeled “Call forwarding,” “Call management,” or “Phone controls.” The interface lets you set a forwarding number and choose the type (always, when busy). This method is excellent if you need to forward a line for another person on your account or make changes away from the physical device.
Changes made here sync directly to the network and affect the line immediately, regardless of the phone’s power or location.
Common Troubleshooting and Why It Might Not Work
Sometimes, you dial the code but nothing happens, or you get an error message. Here are the most common fixes.
First, ensure you have a strong AT&T network signal. The feature codes are commands sent to the network; low signal can interrupt them. Try moving to an area with better coverage.
Double-check the syntax of the dialer code. It must be exact: *21*5551234567# with no dashes, parentheses, or spaces. A single mistyped character will cause it to fail.
Verify that your line has not been barred from call forwarding by AT&T. This is rare but can happen on some very old grandfathered plans or certain business accounts. Contact AT&T customer care at 611 from your mobile phone to confirm the feature is enabled on your line.
If you’re trying to forward to an international number, confirm with AT&T that international call forwarding is allowed on your plan, as extra charges or blocks may apply.
You Forwarded Calls But They’re Not Ringing the Target
If calls seem to vanish, first check the target number. Is the phone powered on and in service? Does it have voicemail set up that might be answering? Call the target number directly from another phone to test it.
Try deactivating all forwarding with #21# and then reactivating it. This resets the network instruction. Also, check for conflicting services. If you have AT&T’s “ActiveArmor” or call screening apps enabled, they might be intercepting calls before the forwarding rule applies. Temporarily disable such apps to test.
Smart Alternatives to Basic Call Forwarding
While standard forwarding is handy, AT&T offers more sophisticated tools for managing calls.
AT&T ActiveArmor (included with most plans) provides spam call blocking and identification, but also offers a “Call Forwarding” management screen within the app, often with a simpler toggle interface than dialer codes.
For business users or those needing a more professional setup, AT&T Mobile Office (a paid add-on) can provide simultaneous ring, where your phone and another number ring at the same time, and more advanced call routing rules.
Don’t forget about voicemail. A well-set-up voicemail greeting that informs callers you’re away and when you’ll return can often be just as effective as forwarding for non-urgent matters. You can also use conditional forwarding to send “No Answer” calls directly to a dedicated voicemail service for transcribing.
Taking Control of Your Incoming Calls
Call forwarding is a simple telecom feature that solves a complex modern problem: being reachable on your terms. Whether you use the quick *21* code for a temporary redirect during a movie, set up a no-answer forward to your office desk phone every workday, or manage it all from the myAT&T app, you now have the knowledge to control where your calls land.
Start by testing it. Forward your phone to a trusted landline or another mobile for just 15 minutes and have a friend call you. Hear the seamless redirect for yourself. Once you’re comfortable, consider setting up a smart rule, like forwarding calls when busy to your voicemail to avoid the endless ringing for your callers.
Your phone number is your digital address. With AT&T’s call forwarding tools, you decide who can reach you there, and when. It’s one less thing to worry about in a constantly connected world.
