What You Will Need

  • Your iPhone or Android phone

  • An internet connection (Wi-Fi or mobile data)

Step 1: Download WhatsApp

Step 3: Enter Your Phone Number

Select your country from the dropdown list (it usually detects it automatically).

Type your phone number without the country code (it is already added).

Tap Next or Done.

Step 4: Verify Your Number

WhatsApp will send a 6-digit code to your phone by SMS. This happens automatically.

  • If the code arrives as a text message, WhatsApp will detect it and verify automatically
  • If it does not detect it, type the 6-digit code manually

This confirms that the phone number belongs to you.

Step 5: Set Up Your Profile

You will be asked to:

  1. Add your name — type your first name (this is what people see when you message them)
  2. Add a profile photo (optional) — tap the circle and choose a photo from your gallery or take a new one

Tap Done or Next.

WhatsApp will scan your phone contacts and show you who already has WhatsApp.

To send your first message:

  1. Tap the pencil icon (iPhone) or chat bubble (Android) to start a new chat
  2. Select a contact from the list
  3. Type your message and tap Send (arrow icon)
