GigSky does not provide an eSIM for Hong Kong that includes a local phone number or the ability to send or receive SMS. Travelers who purchase a GigSky Hong Kong plan will receive only high‑speed data access.
Users can rely on data‑based communication apps such as WhatsApp, Telegram, or iMessage for voice and messaging. However, some destinations may block or restrict VoIP services, so it is advisable to confirm that the apps you need are accessible in Hong Kong before buying a plan.
