Simsima eSIM Data Plans for Taiwan

Simsima does not provide a true unlimited‑data eSIM for Taiwan. All of its offerings for Taiwan are fixed‑data bundles, such as the 100GB plan valid for 180 days or the 50GB plans that last 30, 7, or 15 days. Plans that carry the word “Unlimited” in their name actually give 3 GB per day of high‑speed data and throttle the connection to 1000 kbps after that daily limit is reached. Travelers who expect no data cap should therefore choose one of the large fixed‑data plans, which can be more cost‑effective unless they expect to consume extremely high volumes of data.

Simsima does not provide eSIM plans for Taiwan that include a local phone number or SMS capability. Travelers can only purchase data‑only plans with this provider in Taiwan. However, popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for voice calls and text messages. Because some destinations block or restrict access to specific apps or VoIP services, travelers should confirm that the applications they rely on are available in Taiwan before buying a plan.

Simsima offers 11 single‑country plans and 21 multi‑country plans that cover Taiwan. The available options are divided mainly into fixed‑data‑cap plans, where a set amount of data is provided for the entire validity period, and daily‑data‑cap plans, which limit the amount of data that can be used per day. The price range for these Taiwan‑related plans runs from about $3.65 to $178.48, with data amounts varying between 1 GB and 100 GB and validity periods spanning 5 to 365 days.
