ZenSim does not provide a truly unlimited data eSIM for Taiwan. All listed plans are subject to a data cap—either a fixed allowance such as 20GB per period or a daily limit of 3GB, after which the speed is reduced. Plans whose names include “Unlimited” are not unlimited in the sense of providing unrestricted high‑speed data; they simply carry a high initial quota that is throttled to a lower speed once the limit is reached.
Travelers who need more data can choose from ZenSim’s fixed‑data options. For example, the Taiwan 20GB‑10 Days plan costs $23.00 USD and the Taiwan 20GB‑30 Days plan costs $24.00 USD. These plans offer a larger data allowance than the day‑limit options and can be more cost effective for users who anticipate heavy data use.
