Virtual Numbers (with Caution): While not officially supported or recommended for primary use, some users explore virtual phone numbers (VoIP services) from certain providers.

It's crucial to understand the limitations and potential risks associated with these.

The Critical Nexus of Security and Privacy: Protecting Your Number
While your WhatsApp cell phone number offers unparalleled convenience, its central role in your digital identity also makes it a prime target for various security and privacy threats. Protecting this number is paramount to safeguarding your communications and linked online accounts:

Two-Step Verification (2SV): This is the single most important security feature for your WhatsApp account. It adds an extra layer of protection by requiring a unique PIN that you create, in addition to the SMS verification code, whenever your phone number is registered on a new device. This helps prevent unauthorized access even if someone gets hold of your SIM card.
SIM Swap Scams: Be acutely aware of SIM swap fraud, where criminals trick your mobile carrier into transferring your phone number to their SIM card. Once they control your number, they can intercept WhatsApp verification codes and gain access to your account, potentially leading to further compromise of linked banking, email, or social media accounts. Report suspicious network activity to your carrier immediately.
