eSimpli does not offer a truly unlimited data eSIM for Taiwan. The plans that include “Unlimited” in their name provide a fixed allowance of 1GB per day with high‑speed 5G for the set validity period and then throttle the connection to 1250 kbps once the daily limit is reached. If you need a larger, continuous data budget, eSimpli sells fixed data plans such as the eSIM Taiwan 20GB 30 days plan, which gives 20 GB of high‑speed data for 30 days, or the eSIM Taiwan 10GB 30 days plan, which includes 10 GB for the same period. These fixed‑data options can be more cost‑effective for travelers who require substantial data usage without the reduced‑speed penalty that follows the daily allowance.
