Simsima eSIM Data Plans for Taiwan

Simsima’s plans that carry the name “Unlimited” for Taiwan provide 3 GB of high‑speed data per day and flag a reduced speed of 1000 kbps once that daily allowance is used. Because the data allocation is capped, these plans are not truly unlimited. Travelers who need uninterrupted high‑speed data without a daily cap might prefer Simsima’s fixed‑data offerings, such as the 100 GB plan valid for 180 days, the 60 GB plan for 125 days, the 50 GB plan for 90 days or the 20 GB plan for 30 days. These large‑data options give a single, unrestricted data allowance and can be more cost‑effective for heavy data users.

Simsima does not provide a Taiwan eSIM that includes a phone number or SMS service. The provider offers only data‑only eSIM plans for Taiwan. Travelers can use universal VoIP applications such as WhatsApp, Telegram, or iMessage to place calls and send messages over the data connection, but they will not receive an active phone number nor support standard SMS.

Simsima offers 11 single‑country plans and 24 multi‑country plans for Taiwan. The single‑country plans give you data that is usable only within Taiwan, while the multi‑country plans allow data usage in multiple regions, often including other nearby countries. Across both categories, plan prices range from about $3.56 to $452.76, with data caps that can be as low as 1 GB or as high as 100 GB. Some plans feature a daily data cap, providing a fixed amount of data each day, whereas others use a fixed data cap, offering a set amount of data for the entire validity period.
