GigSky does not provide plans for El Salvador that include a phone number or SMS capability. Travelers can purchase only data‑only eSIMs from GigSky for use in El Salvador.
With a data plan, users can still communicate through VoIP applications such as WhatsApp, Telegram, and iMessage, but the availability of these services may be restricted in some locations. It is advisable to confirm that the apps one relies on are accessible in El Salvador before buying a GigSky data‑only eSIM.
