Voyasim does not offer a Tunisian eSIM that includes a phone number or SMS capability; only data‑only plans are available for travelers.
With such a plan, you can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make voice calls and send messages. However, some destinations may block or restrict certain apps, so travelers should confirm that the apps they need are accessible in Tunisia before purchasing.
