If you’re not in the United States, touch United States, and then select the country where you live. When you register, WhatsApp will send you an SMS message with a verification code. You’ll need to enter this code before you can proceed. If you don’t have SMS on your phone, you can also request an automated phone call.
You can use your real name or a pseudonym. You can add a profile photo on this screen.
If you choose not to permit this access, you can always add friends to WhatsApp manually using their phone numbers.
You can also send a message from the Chats screen.
If you don’t have any friends using WhatsApp, you’ll need to ask a friend to install it on their phone before you can send a message.
