In conclusion, you don't miss reading this text you can use and enjoy this app. 

What is WhatsApp?

WhatsApp is an app to chat and to make  calls or videocalls   for free. You don't need to pay to have WhatsApp. The only thing you need is a cell phone number with internet connection. If you don't have a number  you can use an  app to   get a virtual number, but first you need to verify if WhatsApp accepts that  number because if it doesn’t work with WhatsApp  you will have to wait 15 days to try again.

How to use WhatsApp?

The main function in WhatsApp is to send and receive  messages. It is too easy, you don't need instructions  for  that. That's why I will teach you how to  add contacts or modify your profile.

To add a new contact in WhatsApp only you have to add a contact in your contact list of your phone how you always do it. If  the contact is in the same country  as you, you don't need to put  the country code but if it is in  another country, you will need to put  the country code. 

To change your profile  picture it's simple, just go to  settings and then you can see the button that appears with your photo. If you don't have a photo press the button that appears when you  don't have a profile picture then you will see 2 options:  add a profile picture or change your name, press the add a picture  option and add the picture that you prefer.

Why do people use WhatsApp a lot?

Most people use WhatsApp to chat, to make voice calls or to make video calls. People prefer to make  calls on WhatsApp because they don't waste cell minutes, the calls are by the Internet then they are free. In  WhatsApp you can exchange images or other contents with  a person or groups. Some people like to use it because they have nothing better to do like me.  

How to protect your WhatsApp account?

If  you don’t have a  code, I recommend you to  add one because  someone can steal your WhatsApp  account   and they can change your  account and erase your WhatsApp contacts and information so be careful. If you don't want  that  problem you have to go to  settings, then select verification there you have to activate verification and put your code.
