can I register WhatsApp using virtual phone numbers?

Using a one-time SMS service will get you up and running fast, but WhatsApp will almost certainly flag that number as disposable sooner or later and disable the account. If you want a stable line that lasts, you really need a genuine mobile SIM (or a long-term leased number) warmed up with real chats before you use it for anything serious. Disposables are basically a ticking time bomb.
