Airalo does not offer any eSIM plans that provide a local phone number or SMS capability for Sudan. Travelers can purchase only data‑only plans through Airalo for access to the internet.
If a traveler needs to communicate via voice or text, they can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable to confirm that the necessary apps work in Sudan before purchasing an eSIM.
