Simsima eSIM Data Plans for Taiwan

Simsima does not provide a true unlimited data eSIM for Taiwan. The plans marked “Unlimited – 7 days”, “Unlimited – 10 days”, and “Unlimited – 30 days” actually allow 3GB of 5G high‑speed data per day; after 3GB the speed drops to 1000kbps. Therefore the data isn’t limitless but is throttled after the daily cap.

Travelers looking for large, fixed data allowances can consider Simsima’s fixed bundles, such as the 100GB – 180 days plan, which offers 100GB of 5G data for a set validity, or the 50GB – 30 days plan that gives 50GB for 30 days. These fixed data plans can be more cost‑effective for users who need substantial data but are not extreme heavy‑data consumers.

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 for Taiwan. The available plans span a price range of $3.65 to $178.48 and a data cap range of 1 GB to 100 GB. Some plans feature a daily data cap, while others provide a fixed data amount for the entire validity period.
