Billion Connect does not provide an Iceland eSIM that includes a local phone number or SMS capability. All eSIM plans sold by Billion Connect for Iceland are data‑only. Travelers who need to use a phone number for calls or text messages must rely on VoIP services over the data connection.
Because the plan offers only data, you can still use applications such as WhatsApp, Telegram, or iMessage to make voice and video calls or send messages. Be aware that certain destinations may block or restrict access to specific VoIP apps, so it is advisable to confirm that the apps you rely on are available in Iceland before you buy an eSIM.
