esimzon does not provide Hong Kong eSIM plans that include a local phone number or SMS capability. The provider sells only data‑only eSIMs for Hong Kong, with no outbound or inbound voice or text service.
Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. It is advisable to confirm whether these services are accessible in Hong Kong before purchasing a plan, as some destinations may block or restrict specific apps or VoIP services.
