Yes, for convenience. Buying at the airport or 7-Eleven requires queuing, currency exchange, and completing the mandatory ID registration process. With Cellesim, you buy online, receive the QR code instantly via email, and land in Hong Kong already connected, allowing you to order an Uber or check the Airport Express schedule immediately.
