WhatsApp Messenger is one the most messaging app used around the world and you must be one of their users. Do not miss the opportunity to send text messages, photos, videos and even audio files to your friends and family. In few steps, you can install WhatsApp on your Android Smartphone
The minimum requirements are to have a Smartphone that runs with Android 2,1 or above, and internet data plan (3G or 4G or Wi-Fi). Tablet devices are not supported.
You can install it directly from your Smartphone using Google Play Store. First you need an account of this store, that is, a gmail account. Search the app on Google Play Store and click on the Install button. After ask some data, you can simply wait for the download to finish.
For some time, WhatsApp developers charge 0,99$ each year by downloading this app, but if you already paid for this service and you only want to download the app again because you have bought a new mobile phone you will not be asked to pay for it again. Personally, I think it is worth it, one dollar for one year and you can send thousands of messages, share photos and videos with all your contacts.
