Call forwarding on T-Mobile

Dial three short codes from your cell phone, and optionally a fourth to choose how long it rings first.

Your receptionist number

Replace XXXXXXXXXX below with your receptionist's 10-digit number from your account, with no spaces or dashes.

Turn it on

  1. 1

    Dial this code and press Call, for calls you don't answer:

    **61*1XXXXXXXXXX#
  2. 2

    Dial this code for when your phone is off or has no signal:

    **62*1XXXXXXXXXX#
  3. 3

    Dial this code for when you're already on a call:

    **67*1XXXXXXXXXX#
  4. 4

    Optional: choose how long your phone rings before forwarding (5 to 30 seconds; this example uses 20):

    **61*1XXXXXXXXXX**20#

On an iPhone

The Call Forwarding switch in iPhone Settings forwards every call, so your iPhone would never ring. Don't use it for your receptionist. Instead, open the Phone app's keypad and dial your carrier's codes from its guide. They work on any iPhone.

On Android

The codes above work on any Android phone. Google Pixel and most others: Phone app, three-dot menu, Settings, Calls (or Calling accounts, then your carrier), Call forwarding. Turn on When busy, When unanswered and When unreachable, each with your receptionist number. Samsung Galaxy: Phone app, three-dot menu, Settings, Supplementary services, Call forwarding, Voice call.

Test it

From a different phone, call your business number and don't answer. After a few rings your receptionist picks up, and the call shows in your account within a minute.

Turn it off

  • Reset forwarding to T-Mobile's normal settings (your voicemail comes back):

    ##004#

Good to know

  • Wait for the confirmation message after each code before dialing the next one.
