How to Use WhatsApp on a Windows PC without Phone or SIM
Unlike WhatsApp for Web, which needs a constant connectivity from your phone as well as from your PC in order to use WhatsApp in a browser, in this case, you use Android software emulator Bluestacks in order to install and activate Whatsapp for your own use.
You need to activate and enable Google Play Store in order to download Whatsapp for Android from the Play store. I have already spoken about enabling the Play Store in the software in an earlier post.
Once you have downloaded and installed the App, you need to have an active SIM connection on a mobile phone to use the activation code. Once done, you do not need any constant connectivity with your phone and can be used, even when the phone is switched off.
Whats more, you can also use Whatsapp Calling feature to call your Whatsapp contacts.
Here are the screenshots:
Activating Whatsapp is a onetime process and you can do that without using a smartphone. You only need to receive an SMS.
I hope this was helpful. Cheers!
