nextSIM does not offer a truly unlimited high‑speed data eSIM for Indonesia. Every plan that carries the word “Unlimited” in its name actually provides a capped amount of high‑speed data—1 GB or 2 GB—and after that cap is reached the speed is throttled to a reduced rate (512 kbps or 2000 kbps). Because of this throttling, such plans cannot be considered unlimited in the strict sense.
Travelers who need a larger, unrestricted data allowance can instead choose from nextSIM’s fixed data plans. For example, a 30‑day eSIM with 100 GB of high‑speed data is available, as is a 30‑day eSIM offering 50 GB of data. These fixed‑cap plans provide high‑speed data without a reduction in speed, making them a more cost‑effective option for users who expect heavy data usage in Indonesia.
