# SMS

> Text customers from your business name when WhatsApp can't reach them, through your own Termii account.

SMS goes out through [Termii](https://termii.com) on its transactional route, so numbers on Do-Not-Disturb still get it. Use it for replies and updates to your own customers, never promotions.

## Before you start

* **A Termii account** with an approved sender ID: the name customers see the SMS is from, usually your business name.
* **Owner access in Frictionless,** on the **Starter plan or above**.

**1. Copy your Termii API key**

In Termii, open **Settings → API token** and copy the API key and the API address (base URL).

**2. Connect your Termii account**

In Frictionless, open **Channels → SMS** and paste both under **Connect your Termii account**. Your keys are encrypted and never shown again, even to you.

**3. Pick a sender ID**

Choose one of the sender IDs Termii has approved on your account. If none is approved yet, request one in Termii first. Termii approves each name by hand, usually in 1 to 2 working days.

## How it works

* **Customers can't reply to a sender name.** Ask them to message you on WhatsApp instead.
* **Termii bills your account** for each SMS. 160 characters is one SMS; an emoji makes it 70.
* **Turning SMS off** stops your team texting customers. Past SMS stay in their chats.
