Billion Connect does not provide a Global (World) eSIM plan that includes a phone number or SMS capability; only data‑only plans are available for this destination.
Travelers can still use popular VoIP and messaging applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages. However, because access to these services can be restricted or blocked in some regions, it is important to check that the apps you rely on are available in the destinations you plan to visit before purchasing a plan.
