How to Set Up Call Forwarding on AT&T, Verizon & T-Mobile

As a busy contractor or service pro, the hardest part of the job is often just answering the phone. When you're crawling under a home, up on a roof, or meeting an inspector, stopping every ten minutes to answer calls kills your momentum. But letting those calls roll to voicemail means losing valuable jobs to competitors down the street.

The quickest fix is call forwarding. It takes less than 60 seconds to set up, requires zero technical know-how, and sends your incoming calls straight to your Biz Quantum Leap tracking number and 24/7 AI receptionist. Here is the plain-English, step-by-step breakdown for every major US phone carrier.

1. Verizon Wireless

Verizon makes call forwarding simple using standard dial codes right from your phone's keypad. You can also turn it on or off from the My Verizon app.

Option A: Forward ONLY missed and busy calls (Recommended)

This lets your phone ring normally first. If you don't pick up after 3 to 4 rings, the call transfers over to your AI receptionist so the job is captured:

1. 1Open your phone's Phone / Dial pad app.
2. 2Dial *71 followed immediately by your 10-digit Biz Quantum Leap tracking number (for example: *716025550199).
3. 3Tap the green Call / Send button.
4. 4Wait for a confirmation tone or a short recorded message confirming activation, then hang up.

Option B: Forward ALL calls immediately

1. 1Open your dial pad.
2. 2Dial *72 followed immediately by your 10-digit tracking number (e.g., *726025550199).
3. 3Press Call. Listen for the confirmation beeps or voice confirmation, then hang up.

Whenever you want your phone back to normal, simply open your dial pad, dial *73, and hit Call. You will hear a confirmation tone and forwarding is cancelled.

2. AT&T Wireless

AT&T lines use standard GSM star-and-pound codes. You can also turn on all-call forwarding through your iPhone or Android built-in settings.

Option A: Forward ONLY unanswered or busy calls (Recommended)

1. 1Open your phone's dial pad.
2. 2Dial **004* followed by your 10-digit tracking number, then add the # symbol at the end (for example: **004*6025550199#).
3. 3Press Call / Send.
4. 4A pop-up message will appear on your screen saying 'Setting Registration Succeeded' or 'Call forwarding active'. Tap Dismiss.

Option B: Forward ALL calls immediately

1. 1Dial **21* followed by your 10-digit tracking number and # (e.g., **21*6025550199#).
2. 2Press Call / Send.
3. 3Wait for the confirmation screen, then tap Dismiss.

How to turn off forwarding on AT&T

To cancel all forwarding rules on AT&T, dial ##004# (for conditional forwarding) or ##21# (for all calls) and hit Call. Or dial ##002# to wipe clean all active forwarding rules at once.

3. T-Mobile (and Metro by T-Mobile)

T-Mobile uses the same universal GSM codes as AT&T, which work instantly on any smartphone running on the T-Mobile or Metro network.

Option A: Forward when you don't answer or are on another call

1. 1Open your dial pad.
2. 2Dial **004* followed by your 10-digit tracking number, ending with # (e.g., **004*6025550199#).
3. 3Press Call. You will see a carrier confirmation message confirming call forwarding when busy or unanswered.

Option B: Forward ALL calls immediately

1. 1Dial **21* followed by your 10-digit tracking number and # (e.g., **21*6025550199#).
2. 2Press Call. The network will confirm that all incoming calls are being forwarded.

How to turn off forwarding on T-Mobile

Dial ##004# and press Call to stop conditional forwarding, or dial ##21# to stop all-call forwarding. If you ever want to reset all forwarding settings to default, dial ##002#.

4. Setting it up directly in your smartphone settings (iPhone & Android)

If you prefer clicking through a visual menu instead of dialing star codes, your phone has built-in call forwarding settings for all-call forwarding:

On iPhone (Apple iOS):

1. 1Open the Settings app on your iPhone.
2. 2Scroll down and tap Phone (or Apps > Phone on iOS 18+).
3. 3Tap Call Forwarding.
4. 4Toggle the green switch to ON.
5. 5Tap Forward To and type in your 10-digit Biz Quantum Leap tracking number.
6. 6Tap Back. A small phone-with-an-arrow icon will appear in your status bar to show it is active.

On Android (Samsung Galaxy, Google Pixel, Motorola):

1. 1Open your native Phone app.
2. 2Tap the 3 dots in the top right corner and choose Settings.
3. 3Tap Supplementary services (on Samsung) or Calling accounts / Calls > Call forwarding (on Pixel & Motorola).
4. 4Choose Voice call > Call forwarding.
5. 5Pick either 'Always forward' or 'Forward when unanswered'.
6. 6Enter your 10-digit Biz Quantum Leap tracking number and tap Turn on / Enable.

How to test your forwarding in 30 seconds

Never assume call forwarding is working without testing it once. Here is the foolproof 30-second test:

1. 1Grab a second phone (a spouse's phone, employee's phone, or your home phone).
2. 2Call your normal business cell number.
3. 3If you set up unconditional forwarding, your phone should NOT ring, and you should hear your AI receptionist answer promptly.
4. 4If you set up conditional forwarding, let your phone ring 3 to 4 times without touching it. It should automatically redirect and your AI receptionist will answer.
5. 5Speak a test sentence (like: 'Hi, I need an estimate for my water heater in Mesa') to confirm the AI takes down your information.
6. 6Hang up and check your phone — within seconds you should receive a notification with the captured lead details.
