# Send your first Viber message

To use Viber Business Messages on the Infobip platform, you need to meet the following requirements:

- Create an [Infobip account](https://www.infobip.com/docs/essentials/getting-started/create-an-account) (if you do not already have one) by completing the platform onboarding.
- [Enable your Viber configuration](https://www.infobip.com/docs/viber/business-messages/get-started) and obtain approval from Viber.

## Start your free trial

New Infobip users automatically receive a **60-day** [free trial](https://www.infobip.com/docs/essentials/getting-started/free-trial) and are assigned Infobip's **test sender**. Use this Infobip-branded sender to test your Viber communication.

**Limitations**:

- You can send **100 free Viber messages** to 5 recipients.
- You can only send messages to **verified numbers**.
- To start sending live traffic, **register a dedicated Viber sender** during the onboarding process in our web interface.

When your free trial ends, a banner will appear at the top of your homepage. You can add funds by clicking the Upgrade now button, allowing you to continue sending messages to your customers.

## Upgrade to a paying account

When ready, you can upgrade to a [paying account](https://www.infobip.com/docs/essentials/getting-started/paying-account). Select the **Add funds** options at the top of the page and choose a billing option. Once you add funds to your account balance, it will no longer be in free trial mode.

## Start using Viber

1. **Start using Viber on our [web interface](https://portal.infobip.com/).**
   At the top of the page, select whether you are a **business user** or a **developer**:
