# T-Mobile Call Forwarding to an AI Receptionist

Source: https://insertchat.com/call-forwarding/t-mobile

> Forward T-Mobile calls to InsertChat’s AI receptionist from your phone’s settings: always, or only when unanswered, busy, or unreachable. Verify and undo it.

On T-Mobile, forwarding is set in the phone’s own call settings. Forward every call, or set separate destinations for unanswered, busy, and unreachable calls.

## Finish the setup in InsertChat

1. **Enter your business number.** In your assistant’s phone settings, choose Forward my existing number, enter it, and check compatibility. Confirm the provider you pay for phone service.
2. **Forward to your routing number.** Choose when calls forward, then follow your provider’s steps to send them to the private routing number InsertChat creates. Never publish that number.
3. **Verify with a test call.** InsertChat places a verification call. For unanswered-or-busy forwarding, let it ring without answering so your provider’s rule can forward it.

## Where are the forwarding settings on my phone?

Open the Phone app’s settings and look for Call forwarding; the exact menu names vary by device. Set each condition you want, such as unanswered, busy, and unreachable, to your private routing number.

## Will my voicemail still pick up?

Forwarding unanswered calls sends them to the AI receptionist instead of voicemail. If voicemail keeps answering first, make sure the unanswered condition points to your routing number, then run verification again.

## Does forwarding my number cost extra?

The first active line is included with your InsertChat plan; additional lines are $10 per month plus voice minutes. Your phone provider may also count forwarded calls against your plan, so check your plan with them.

## What if my provider is not listed?

Choose Another provider during setup. Ask your provider to forward all calls, or unanswered and busy calls, to your private routing number, keep caller ID passthrough on when offered, and make carrier voicemail ring longer than the forwarding timeout.
