Absolutely. DataESIM provides a data-only connection, meaning it does not assign a new local phone number to your device. Consequently, your existing WhatsApp account, including all chat histories, group memberships, and contacts, will remain fully functional and associated with your primary phone number. You can continue to use WhatsApp for messaging and VoIP calls as you normally would. If WhatsApp prompts you to update to a new number, explicitly decline this option to retain your original account configuration.
