mysim24 does not offer a truly unlimited high‑speed data eSIM for Taiwan. The plans that carry “Unlimited” in their name give 1 GB/day (or 2 GB/day for “Unlimited Plus” and 5 GB/day for “Unlimited Premium”) at full speed; after the daily allowance is used the remaining data is still available but throttled to 512 kbps (or 2 Mbps for “Unlimited Plus” and “Unlimited Premium”). These are fixed‑data plans, not Pay‑as‑you‑go options, and the data is subject to a – and not an unlimited – speed reduction once the daily high‑speed quota is reached.
Travelers who need more bandwidth can choose one of the large fixed‑data bundles that mysim24 offers for Taiwan, such as the 5 GB/day “Unlimited Premium” plan for 3, 5, 7, 10, 15 or 20 days, or the 2 GB/day “Unlimited Plus” plan for 3, 5, 7, 10, 15, 20 or 30 days. There are also high‑cap options like the 100 GB 30‑day or 180‑day plans that give a larger pool of data without the daily high‑speed limitation. These fixed‑data plans are typically more cost‑effective for heavy data users compared with the capped, throttled “Unlimited” plans.
