It's easy! Just go to the app store/s of your phone's Operating System (OS) and download WHATSAPP
- Windows Phone
Do note that some apps may not be available in a particular OS. The app itself is free but downloading it will require regular data charges if you are using Globe's mobile data connection, unless subscribed to a data plan/promo. Upon installation of the app in your phone, you can already use WHATSAPP20 for free even without WiFi.
