WhatsApp Messenger is an incredibly easy to use and popular mobile messaging system that is encrypted end-to-end for all users. One reason it’s popular is that the app allows users to exchange texts and media messages through their internet provider data plan or using Wi-Fi without having to pay for SMS.

The only caveat to using WhatsApp is that you can only message people who use WhatsApp. For instance, if your contacts are using Google Hangouts or their default messaging app, they won’t be able to communicate with you unless they install WhatsApp.

Here’s how to install and use WhatsApp Messenger on a Verizon-branded Nexus 6.

Installing WhatsApp Messenger

  1. Open the Google Play Store on your Android device.
  2. Search for whatsapp.
  3. Locate and tap the entry by WhatsApp Inc.
  4. Tap Install.
  5. Read the permissions listing.
  6. If the permissions listing is acceptable, tap Accept.

After the installation completes, you should see a launcher for WhatsApp Messenger in your App Drawer or on your home screen. Tap the launcher to fire up the application. The first time you use it, follow these steps.

  1. Agree to the EULA.
  2. Grant WhatsApp permission to access your contacts.
  3. Grant WhatsApp permission to access your photos, media, and files.
  4. Verify your phone number.
  5. Enter your device phone number and then tap the Send button. WhatsApp Messenger can automatically detect the verification code, so you don’t have to open your current messaging app to retrieve the digits.
  6. Grant WhatsApp permission to send and view SMS messages by tapping ALLOW when prompted. WhatsApp will finally detect the incoming verification code.
  7. Enter a name for your profile and tap NEXT.

Now you’re ready to begin using WhatsApp.

Using WhatsApp Messenger

Beyond that, using WhatsApp is as simple as using any other messaging app. You might want to check the ability to configure the media auto-download. With this feature (Menu | Settings | Data Usage), you can define what is automatically downloaded when using mobile data and when connected to Wi-Fi (Figure C).

To prevent anything from auto-downloading while using your data plan, uncheck Images for mobile data and check everything for Wi-Fi (Figure D).

One of the best messaging apps

Give WhatsApp a try, and see if it doesn’t quickly wind up becoming your default messaging app — at least for contacts already using or willing to use it.
