AeriSIM does not provide an unlimited‑data eSIM for Taiwan. All of its Taiwan‑specific offerings have a hard data cap of 50GB.
Instead, AeriSIM sells fixed data plans with a 50GB allowance that can be used within a set period. For example, the “Taiwan eSIM – 3 Days / Total 50GB” plan offers 50GB for 3 days at $22.02 USD, while the “Taiwan eSIM – 7 Days / Total 50GB” provides the same data for 7 days at $24.04 USD. Similar 5‑day and 10‑day options are also available, and a broader “Asia & Europe 52 Countries eSIM – 3 Days / Total 50GB” plan includes Taiwan coverage. These fixed‑data plans can be more cost‑effective for most travelers unless a user requires truly unlimited data.
