Voyasim does not provide a South Sudan eSIM that includes a local phone number or SMS capability. The available plans from this provider are strictly data‑only, so travelers cannot receive inbound calls or text messages on a South Sudan number.
Users who need voice or messaging can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or limit access to certain apps or VoIP services, so it is advisable to confirm that these services will work in South Sudan before purchasing a data‑only eSIM.
