# Set up a phone number in Infinity3

Use a business phone number to handle supported calls and text messages through Infinity3.

#### Before you start

You’ll need access to phone settings and a phone service enabled for your account. Number availability, features and charges depend on your setup.

For UK numbers, you may need an approved regulatory bundle containing business, identity or address information. Infinity3 can help you identify the requirements.

#### Add a number

1. Log into the Infinity3 Platform at app.infinity3.ai.
2. Open **Settings** → **Phone System** → **Manage Numbers**.
3. Select **Add Number**, then **Add Phone Number** if prompted.
4. Choose the country and the type of number you need.
5. Check the number’s capabilities. Choose an SMS-capable number if you want to send texts.
6. Select an approved regulatory bundle if required.
7. Review the displayed number and usage charges before completing the purchase.

If these options aren’t available, contact Infinity3 to arrange your phone setup.

#### Configure incoming calls

Open the number’s configuration and choose who should receive incoming calls. Depending on your setup, calls can ring team members, forward to another number or reach voicemail.

Call the number from an external phone to check the route before sharing it with customers.

#### Things to know

- Adding a number does not transfer an existing business number.
- Voice support does not automatically mean SMS support.
- Number rental and usage charges may apply.

If you need to keep your existing number, contact Infinity3 to discuss the available options.
