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.
| Action | Code | When 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
- 1Open your Phone app
Tap the Phone/Dialer app on your T-Mobile phone
- 2Dial the forwarding code
Type:
**21*followed by the 10-digit forwarding number, then# - 3Press Call
Tap the green Call button to activate
- 4Wait 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.

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
- Download the T-Mobile DIGITS app from App Store or Google Play
- Sign in with your T-Mobile account
- Follow the prompts to pair your devices
- 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
| Action | Code |
|---|---|
| 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#

##004#
Deactivation Codes by Type
| To Cancel | Dial Code |
|---|---|

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

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.
