  2. Start the installation: Tap the WhatsApp icon and press the “Install” button.   
  3. Read the terms of service: Once the app is installed, open it and carefully read the terms of service and privacy policy.
  4. Agree to the terms: If you agree to the terms, tap “Agree and continue”.
  5. Enter your phone number: Type your valid phone number in international format, complete with the country code. It is essential to have an active phone number to receive the verification code.   
  6. Verify your number: You will receive an SMS with a six-digit verification code. Enter it into the app to verify your number. In some cases, you might receive a call with the verification code.   
  7. Create your profile: Enter your name and, if you wish, a profile picture.
  8. Grant permissions: WhatsApp will ask for access to your contacts and, if you wish, to your photos, videos, and media files. Grant the necessary permissions to use all the app’s features. The way to grant permissions may vary slightly depending on the Android version and the device manufacturer.

After completing these steps, WhatsApp will be installed and ready to use on your Android device. The app icon will appear on your home screen.

iOS (iPhone and iPad)

  1. Download the app: Open the App Store on your iPhone or iPad and search for “WhatsApp Messenger”.
  2. Start the installation: Tap the WhatsApp icon and press the “Get” button.
  3. Read the terms of service: As with Android, carefully read the terms of service and privacy policy.
  4. Agree to the terms: Tap “Agree and continue” to accept the terms.
  5. Enter your phone number: Select your country from the drop-down menu to automatically add the international prefix and enter your valid phone number. Make sure the number entered is correct and that your SIM is active.
  6. Verify your number: You will receive a six-digit verification code via SMS or a call. Enter the code into the app. If you don’t receive the code via SMS, you can request an automated call with the code.
  7. Create your profile: Enter your name and add a profile picture, if you wish.
  8. Grant permissions: Grant WhatsApp access to your contacts and, if you wish, to your photos, videos, and media files. You can manage WhatsApp permissions later from your device’s settings.   

As you can see, the steps to install WhatsApp on Android and iOS are very similar, with some minor differences in the interface and verification options.
