Can I make a call in WhatsApp without a SIM card - in detail?
To determine whether you can make a call on WhatsApp without a SIM card, it is essential to understand how the platform functions and what requirements are necessary for its operation.
WhatsApp, owned by Meta Platforms Inc., is a messaging and voice-over-IP (VoIP) service that allows users to send text messages, make voice and video calls, and share media files with individuals or groups. The core functionality of WhatsApp relies on an active internet connection, either through Wi-Fi or mobile data. However, the initial setup and verification process requires a SIM card for authentication purposes.
During the installation and verification phase, WhatsApp sends a unique code to your phone number via SMS. This code is used to verify your account and confirm that you are the legitimate owner of the phone number. Without a SIM card, you cannot receive this SMS code, making it impossible to complete the initial setup process. Consequently, you will be unable to make calls or use any other features of WhatsApp if your device is not associated with a valid phone number.
Moreover, even after the initial setup, WhatsApp periodically requires re-verification to ensure that the account remains active and secure. This process also involves sending an SMS code to your registered phone number. Failure to receive this code due to the absence of a SIM card will result in the temporary deactivation of your WhatsApp account, preventing you from making calls or accessing other services until re-verification is successful.
In summary, while WhatsApp primarily utilizes an internet connection for its communication services, the presence of a SIM card is crucial for the initial setup and periodic re-verification of your account. Without a SIM card, you will be unable to make calls or use any other features on WhatsApp. It is therefore recommended to have an active SIM card in your device to ensure uninterrupted access to WhatsApp's services.
