User Guide: Getting Started
Welcome to WhatsApp! This is a multiplatform mobile phone messaging service that uses your phone's internet connection to chat with and call other WhatsApp users.
Before you download and install WhatsApp, make sure WhatsApp supports your phone type. Please check this here.
To download WhatsApp, visit this link on your phone. Once installed, ensure that the friends who you wish to message have WhatsApp installed on their phones. If they do not show up under the Favorites screen (Contacts tab on Android), carefully add their numbers to your phone contacts:
- Enter the number the same as you would if you were to make a phone call to that person. Double check to make sure you entered the number correctly.
- If this is an international phone number, do not use any exit codes or leading 0s. Start all international phone numbers with a + sign, followed by the country code. For specific examples and instructions, see this article.
- Open WhatsApp and refresh your Favorites list (Contacts tab on Android).

Provided you have an adequate data plan, it is free to send messages over WhatsApp. More details concerning cost are available here.
