GigSky does not sell eSIM plans for Indonesia that include a phone number or SMS capability. All of its Indonesia offerings are data‑only, meaning there is no inbound or outbound voice or text service. Travelers who need to make calls or send messages can rely on internet‑based apps such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block or restrict these services, so it is advisable to confirm their availability in Indonesia before purchasing.
