No, voilà does not provide an unlimited data eSIM plan for Indonesia. All of the plans listed for Indonesia have a fixed data cap, the largest being 50GB for 30 days or 180 days, and another 20GB for 30 days.
Travelers who need a large amount of data can choose one of these fixed data plans. For example, the 50GB plan valid for 30 days costs $34.90 USD and offers 5G coverage in Indonesia, while the 20GB plan valid for 30 days costs $16.80 USD and also offers 5G coverage. Fixed data plans can be more cost‑effective for most users unless they are extremely heavy data consumers.
