Billion Connect does not provide Hong Kong eSIM plans with a phone number or SMS capability. The provider’s Hong Kong offerings are data‑only plans.
Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict the use of specific VoIP services, so it is advisable to verify that the apps required are accessible in Hong Kong before purchasing a plan.
