Even if your iPhone or Android Phone does not have a SIM Card installed on it, you download and install WhatsApp on it and use you phone to make free voice/video calls to other WhatsApp users.
Use WhatsApp Without SIM Card
WhatsApp prompts users to provide a phone number only during the setup process. Once the setup process is completed, it does not matter whether your mobile device has a SIM card installed on it or not.
This means, you can always connect your iPhone or Android Phone without SIM to a Home or Office Wi-Fi network and download WhatsApp on your mobile device from the App Store or Google Play Store.
Once WhatsApp is downloaded and available on your mobile device, you can use WhatsApp on your iPhone or Android Phone without SIM by using any of the following alternative methods to verify your WhatsApp account.
1. Use WhatsApp Without SIM by Using Phone Number from Another Device
