WonderConnect does not provide an Iceland eSIM that comes with a phone number or SMS capability, so only data‑only plans are available from the provider.
Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but some destinations may restrict or block specific apps or VoIP services, so it is a good idea to confirm that the apps you need are accessible in Iceland before purchasing a plan.
