Wiiline does not offer a truly unlimited data eSIM for Taiwan. Every Wiiline product listed for Taiwan has a specified data cap, such as 500 MB, 1 GB, 2 GB, 3 GB, or larger bundles like 100 GB for a fixed period.
Travelers who need a large amount of high‑speed data can choose from fixed data plans instead. For example, the Taiwan Unlimited 3GB/day – 5Days plan gives 3 GB of high‑speed data each day for five days, after which the speed drops to 384 kbps. A longer‑term alternative is the Asia 100GB – 30Days plan, which provides 100 GB of data for 30 days. These fixed data plans can be more cost‑effective for most users, unless a traveler expects to use more data than the capped amount.
