Route an SMS-enabled number to one or more users so they can send and receive texts in the Webphone. Incoming texts appear in the Webphone of every user you choose.



US numbers can receive SMS. To send SMS from a US number, register an A2P 10DLC campaign first. See [SMS registration for US numbers](https://kb.voipcloud.online/us/services/phone-numbers/us-sms-a2p-registration/).

**On a free trial?** SMS isn't available during the free trial. You can set this up once your account is active. See [Your free trial](https://kb.voipcloud.online/us/getting-started/free-trial/).

## Before you start

- An SMS-enabled number, such as a virtual mobile number.
- Each user needs a Webphone device (**Webphone browser**, **Webphone desktop** or **Webphone mobile**). SMS doesn't work on desk phones or third-party softphones. See [User](https://kb.voipcloud.online/us/pbx/accept-make-divert/user/).
- To send texts, the user's licence needs an **SMS plan**. Set it in [PBX licences](https://kb.voipcloud.online/us/services/pbx-licences/).

## 1. Route the number to users

1. Go to **Services** › **Phone numbers** and open the **Active numbers** tab.
2. Next to the number, click **SMS routing**.
3. Under **Users who can receive and send SMS from this number in the Webphone**, select each **User**. To add more users, click **+**.
4. Click **Save**. The change can take up to 10 minutes.

Some numbers can only receive SMS until Application-to-Person messaging (A2P) is activated, because of regulatory requirements. The window then says **Users who can receive SMS from this number in the Webphone** and shows a note.

## 2. Check the user's SMS settings (optional)

In the PBX, open the [User](https://kb.voipcloud.online/us/pbx/accept-make-divert/user/) settings:

- **Default SMS ID** picks the number used when the user starts a new SMS chat. It's useful when a user has several SMS-enabled numbers.
- **Allowed alphanumeric SMS IDs** lets them send from your company name instead of a number. You need to register a sender ID first: see SMS sender ID register.

Click **Save** and **Apply configuration** after any change.

## Check it works

1. Sign in to the Webphone as one of the users.
2. Send a text from a mobile to the number. It should appear in the Webphone.
3. Reply from the Webphone. The mobile should receive it from your number.

## Rules and limits

- A standard SMS holds 160 characters. Longer messages are split into parts of 153 characters, up to 3 parts (459 characters).
- If a message has emojis or non-Latin characters, one SMS holds 70 characters and the maximum is 201 characters.

To check whether you can send SMS to a destination, look for an outbound SMS rate in [Rates search](https://kb.voipcloud.online/us/billing/check-call-rates/).
