Installing WhatsApp on a smartphone requires a valid mobile phone number. However, as you will discover in this guide, there are different methods for using WhatsApp on a device that does not have a SIM card. Here's how..
Get the WhatsApp verification code without giving your mobile number
In just a few years, WhatsApp (What's Up in English) has become one of the most popular instant messaging apps in the world. What started out as a tool to modernize SMS quickly turned into a success story. Several tens of billions of messages pass through its mobile platform every day.
But like any application, WhatsApp has its pros and cons. When registering, the messaging service will require that you provide a mobile phone number. I warn you immediately useless to try to cheat. 
Because as soon as the number is entered, WhatsApp will send you a security code by SMS which you will have to enter directly in the app..
Obviously if you use a smartphone without a SIM card , this may cause some problems. Rest assured here is a very simple alternative to set up so that you do not have to enter your mobile number during the registration process. This is news that should comfort everyone who does not wish to give their mobile number to Facebook (the parent company of WhatsApp).
Use your landline number
As a VoIP service, WhatsApp needs to authenticate the owner of an account. But rather than using a mobile phone, we will use the one on your landline. With this method you will be able to use WhatsApp on a smartphone without a SIM card..
- Open the WhatsApp application on your smartphone
- Start the registration process
- Select your country then enter your landline number
