SimOptions does not provide an eSIM plan for Hong Kong that includes a phone number or SMS capability. The eSIMs sold by SimOptions for Hong Kong are data‑only, so travelers who need voice or text communication must rely on internet‑based applications such as WhatsApp, Telegram, or iMessage. Those apps can usually be used over the data connection, but some destinations may block or restrict certain VoIP services, so it is advisable to check that the apps you intend to use are accessible in Hong Kong before purchasing.
