{% hint style="info" %}
Although you can start using your WhatsApp API immediately, you are limited to the following: 

* Adding **2** numbers to your account
* Sending business-initiated templated messages to a maximum of **250** unique recipients per day
* Unlimited user-initiated messages

To remove these limitations, [verify your Business Account](https://guides.clickatell.com/whatsapp-channel/getting-started/get-business-verified).
