GigSky does not provide Seychelles eSIM plans that include a phone number or SMS capability; the only plans available for Seychelles are data‑only eSIMs.
Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify before purchasing that these services are accessible in Seychelles, as some destinations may block or restrict them.
