nextSIM does not provide a truly unlimited data eSIM for Taiwan. All plans listed for Taiwan have a specified data cap, after which the speed is reduced; for example, the “eSIM Taiwan Unlimited Plus 1Days Standard” allows 2GB of high‑speed data before throttling to 2000kbps.
Travelers who need a larger amount of data can choose from the fixed‑data plans that nextSIM offers. Among these are the 100GB 30‑day plan and the 50GB 30‑day plan, both available for Taiwan and delivered via 5G. These plans give a large high‑speed data allowance for a set validity period, and may be a more cost‑effective option for users who consume a lot of data while staying in Taiwan.
