Simsima’s plans that carry the word “Unlimited” in their name are not truly unlimited. Each of those options provides 3GB of high‑speed data per day. Once the 3GB quota is used, the network speeds drop to 1000 kbps. There are no plans that offer unlimited high‑speed data in Taiwan.
Travelers can instead choose one of Simsima’s fixed‑data eSIM plans. For example, a 100 GB plan is available for 180 days at $84.00 USD, and a 50 GB plan lasts 90 days for about $102.90 USD. A 20 GB plan for 30 days costs $16.46 USD and is available only in Taiwan, which may be more cost‑effective for most 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.
