How to Forward Calls from T-Mobile to an AI Receptionist

Last updated: March 2026

TL;DR

Forward your T-Mobile calls by dialing **21* followed by the destination number. The entire process takes under 2 minutes. You can forward all calls or just missed calls. Once set up, calls route to any number you choose, including an AI receptionist like Aira that answers 24/7, books appointments, and takes messages. Plans start at $24.95/mo.


How to Forward All Calls from T-Mobile

Follow these steps to forward every incoming call from your T-Mobile phone to another number. This works with any destination, including an AI receptionist, voicemail service, or another phone line.

  1. Open your phone's dialer
  2. Enter the call forwarding code: Dial **21* followed by the 10 digit phone number you want your calls forwarded to, then #
  3. Press the call button to activate call forwarding
  4. Wait for confirmation tone or message that call forwarding is enabled

Dial Code

**21*[number]#

Alternative: Set Up via App or Online

Set up call forwarding in your phone's settings under Phone > Call Forwarding (iPhone) or Calls > Call Forwarding (Android). T-Mobile does not allow setup via website or app.

Note

You can set different numbers for each conditional forwarding type or use the same number for all.


How to Forward Missed Calls from T-Mobile

Conditional forwarding lets your phone ring first. If you don't answer, the call forwards automatically to another number. This is ideal for sending missed calls to an AI receptionist while still answering calls yourself when you're available.

  1. Open your phone's dialer
  2. Choose the type of missed call you want to forward
  3. For no answer: Dial **61* followed by the forwarding number, then #
  4. For busy: Dial **67* followed by the forwarding number, then #
  5. For unreachable: Dial **62* followed by the forwarding number, then #
  6. Press the call button to activate the setting
  7. Wait for confirmation that conditional call forwarding is active

Why Forward T-Mobile Calls to an AI Receptionist?

Most businesses miss 20 to 40 percent of incoming calls. Every missed call is a lost customer, a missed appointment, or revenue walking out the door. Forwarding your T-Mobile calls to an AI receptionist solves this instantly.

What an AI Receptionist Does with Your Forwarded Calls

  • Answers every call 24/7. No voicemail, no hold music, no missed opportunities. Nights, weekends, holidays, and lunch breaks are all covered.
  • Books appointments automatically. The AI checks your calendar availability and schedules appointments directly during the call. No back and forth needed.
  • Takes detailed messages. When you can't take a call, the AI captures the caller's name, number, reason for calling, and any urgent details. You get a notification instantly.
  • Speaks English and Spanish. Bilingual support means you never lose a caller because of a language barrier. The AI detects the caller's language automatically.
  • Costs a fraction of a human receptionist. Plans start at $24.95/mo for 30 calls. Compare that to $3,000+/mo for a full time receptionist or $500+/mo for a traditional answering service.

The setup takes under 2 minutes. Forward your T-Mobile calls using the steps above, and your AI receptionist starts answering immediately.

T-Mobile supports international call forwarding, so you can route calls from anywhere to your AI receptionist.
