Jetpac does not provide a truly unlimited high‑speed eSIM plan for Taiwan. All of its plans that carry the word “Unlimited” in the name actually supply 3 GB of high‑speed data per day, and once that cap is reached the speed drops to 1024 kbps. This means that the data allowance is capped, not unlimited.
Travelers who need more data can choose from Jetpac’s fixed‑data plans. For example, a 40 GB plan is valid for 30 days and costs $34.99 USD, while a 50 GB plan covers 365 days and costs $249.00 USD. These plans provide higher overall data allowances and may be more cost effective for heavy data users.
