All T-Mobile Call Forwarding Codes

T-Mobile uses standard GSM codes for call forwarding. These codes work on all T-Mobile phones (iPhone, Android, basic phones) and carriers using T-Mobile's network like Metro by T-Mobile and Mint Mobile.

ActionCodeWhen It Forwards
Forward ALL Calls**21*number#All calls - phone doesn't ring
Forward When No Answer**61*number#After phone rings ~20 seconds
Forward When Busy**67*number#When you're on another call
Forward When Unreachable**62*number#Phone off or no signal
Forward to Voicemail*21*123#All calls to T-Mobile voicemail
Turn OFF All Forwarding##21#Cancels unconditional forwarding
Turn OFF All Conditional##004#Cancels all conditional forwarding

Important: T-Mobile does NOT use *72/*73 codes like Verizon. Always use the GSM codes above (**21*, ##21#, etc.) for T-Mobile phones.

Forward All Calls (**21*)

Unconditional call forwarding sends ALL incoming calls to another number. Your phone won't ring - calls go directly to the forwarding destination.

Step-by-Step Instructions

  1. 1
    Open your Phone app

    Tap the Phone/Dialer app on your T-Mobile phone

  2. 2
    Dial the forwarding code

    Type: **21* followed by the 10-digit forwarding number, then #

  3. 3
    Press Call

    Tap the green Call button to activate

  4. 4
    Wait for confirmation

    You'll hear a confirmation tone or see a message. End the call.

// Example: Forward all calls to 555-123-4567

**21*5551234567#

// Turn OFF all call forwarding

##21#

Conditional Call Forwarding

Conditional forwarding only redirects calls in specific situations - when you don't answer, when you're busy, or when your phone is unreachable. Your phone rings first, giving you a chance to answer.

No Answer

Forwards after ~20 seconds of ringing

ON: **61*number#

OFF: ##61#

Check: *#61#

Busy

Forwards when you're on another call

ON: **67*number#

OFF: ##67#

Check: *#67#

Unreachable

Forwards when phone is off/no signal

ON: **62*number#

OFF: ##62#

Check: *#62#

Pro Tip: To set up ALL conditional forwarding types at once to the same number, you would need to dial each code separately. Use ##004# to turn off all conditional forwarding at once.

Call Forwarding on T-Mobile iPhone

T-Mobile iPhones support both the Settings app method and dial codes for call forwarding.

Method 1: Using iPhone Settings

  3. 3. Tap Call Forwarding
  4. 4. Toggle Call Forwarding ON
  5. 5. Tap Forward To and enter the destination number
  6. 6. Tap Back to save

Good News: Unlike Verizon, T-Mobile iPhones DO show the Call Forwarding option in Settings because T-Mobile uses GSM technology.

Method 2: Using Dial Codes (Recommended)

Dial codes work instantly and give you more control over forwarding types:

// Forward ALL calls

**21*5551234567#

// Forward only when no answer

**61*5551234567#

T-Mobile DIGITS (Alternative to Call Forwarding)

T-Mobile DIGITS is a powerful alternative to traditional call forwarding. Instead of forwarding calls to another number, DIGITS lets you use your T-Mobile number on multiple devices simultaneously.

What DIGITS Can Do

  • ✓Use your T-Mobile number on up to 5 devices (phones, tablets, computers)
  • ✓All devices ring simultaneously when you get a call
  • ✓Works on any carrier - use DIGITS on a Verizon or AT&T phone
  • ✓Send & receive texts from all connected devices
  • ✓No traditional "forwarding" - it's true multi-device calling

How to Set Up DIGITS

  1. Download the T-Mobile DIGITS app from App Store or Google Play
  2. Sign in with your T-Mobile account
  3. Follow the prompts to pair your devices
  4. Or visit a T-Mobile store for assistance

DIGITS Pricing: $10/month for "Data with Paired DIGITS" plan to add your number to another device. Some T-Mobile plans include DIGITS at no extra cost.

Metro by T-Mobile & Mint Mobile Codes

Metro by T-Mobile (formerly MetroPCS) and Mint Mobile both use T-Mobile's network, so they use the same GSM call forwarding codes.

Metro by T-Mobile

ActionCode
Forward all calls**21*number#
Forward when no answer**61*number#
Forward when busy**67*number#
Forward when unreachable**62*number#
Turn off all forwarding##21#

Note: Metro by T-Mobile may charge $1/month for the call forwarding feature depending on your plan. Check with Metro support or your account settings.

Mint Mobile

Mint Mobile uses T-Mobile's network, so the same GSM codes work. Use **21*number# to forward and ##21# to cancel. No additional monthly fee for call forwarding on Mint Mobile plans.

Turn Off T-Mobile Call Forwarding

To disable call forwarding on T-Mobile, use these codes:

Turn off unconditional forwarding:

##21#

Turn off ALL conditional forwarding at once:

##004#

Deactivation Codes by Type

  • *#67# - Check busy forwarding status
  • *#62# - Check unreachable forwarding status

Troubleshooting T-Mobile Call Forwarding

Problem: Code doesn't work / "Connection problem"

The forwarding code fails or shows an error message.

Solutions:

  • Make sure you have cellular signal (not just WiFi)
  • Use the format **21*5551234567# with no spaces or dashes
  • Try *21*number# (single asterisk) if double doesn't work
  • Reset by dialing ##21# first, then try again

Problem: Conditional forwarding not working

Calls don't forward when you don't answer or phone is off.

Solutions:

  • First dial ##004# to reset all conditional forwarding
  • Then set up each type individually (**61*, **67*, **62*)
  • On iPhone: Disable Visual Voicemail temporarily to test
  • Check if voicemail is intercepting calls before forwarding activates

Problem: Can't forward to a specific number

Forwarding works to some numbers but not others.

Solutions:

  • T-Mobile only allows forwarding to 10-digit US numbers
  • You cannot forward to international numbers
  • Verify the destination number is active and can receive calls
  • VoIP numbers may have intermittent issues - try a regular cell number

Problem: Calls still going to voicemail

You set up forwarding but calls still go to T-Mobile voicemail.

Solutions:

  • Make sure you used unconditional forwarding (**21*) not conditional
  • Dial *#21# to verify forwarding is active
  • Visual Voicemail may override forwarding - try disabling it
  • Contact T-Mobile support: 1-800-937-8997

Frequently Asked Questions

What is the T-Mobile call forwarding code?

The main T-Mobile call forwarding code is **21* followed by the 10-digit phone number and #. For example, **21*5551234567# forwards all calls to 555-123-4567. To turn off forwarding, dial ##21#.

How do I turn off call forwarding on T-Mobile?

Dial ##21# and press Call to turn off unconditional call forwarding. To disable all conditional forwarding (busy, no answer, unreachable) at once, dial ##004#. Wait for the confirmation tone.

Does T-Mobile charge for call forwarding?

No, T-Mobile does not charge to activate or use call forwarding within the US. There's no per-minute fee for forwarded calls. However, if you forward to an international number (which isn't supported), charges would apply. Metro by T-Mobile may charge $1/month for the feature depending on your plan.

Why doesn't *72 work on T-Mobile?

*72 and *73 are Verizon codes, not T-Mobile codes. T-Mobile uses GSM-based codes: **21* to activate and ##21# to deactivate. This is because T-Mobile uses GSM network technology while Verizon historically used CDMA.

Can I forward T-Mobile calls to an international number?

No, T-Mobile does not allow call forwarding to international numbers. You can only forward calls to 10-digit or 11-digit US phone numbers. For international forwarding, consider using a VoIP service like BubblyPhone instead.

What's the difference between T-Mobile DIGITS and call forwarding?

Call forwarding sends your calls to a different phone number. T-Mobile DIGITS lets you use your same number on multiple devices simultaneously - all devices ring at once, and you can answer from any of them. DIGITS is $10/month or included with some plans.
