GigSky does not provide India eSIM plans that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs for India from GigSky. However, apps that use internet data, such as WhatsApp, Telegram, and iMessage, can normally be used for calls and messaging over the data connection. Availability of these VoIP services may vary, so travelers should verify that the apps they rely on work in India before buying a GigSky eSIM.
