Billion Connect does not provide any Slovenia eSIM plan that includes a phone number or SMS capability. Only data‑only eSIM options are available for travelers in Slovenia.
Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible in Slovenia before purchasing a plan.
