4S eSIM eSIM Data Plans for Taiwan

4S eSIM does not provide a plan that offers unlimited high‑speed data while in Taiwan. Every plan listed as “Unlimited” has a specified data cap and a reduced speed of 1000kbps once that cap is reached, which means the data is not truly unlimited.

Instead, 4S eSIM offers fixed‑data options. For example, a 50GB plan for 5 days costs $37.93 USD, a 20GB plan for 15 days costs $50.04 USD, and a 50GB plan for 30 days costs $140.99 USD. These fixed‑data plans can be a cost‑effective choice for travelers who need a large data allowance without the uncertainty of a throttled “unlimited” option.

4S eSIM does not provide eSIM plans for Taiwan that include a phone number or SMS capability. The provider only offers data‑only plans for this destination. Travelers who need voice or text services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict access to these services, so users should verify availability in Taiwan before purchasing.

4S eSIM lists 54 single‑country data plans and 108 multi‑country plans that can be activated in Taiwan. The available packages span a price range from about $2.02 to $195.83, with data caps ranging from 714 MB up to 50 GB. Some plans offer a fixed data amount for the entire validity period, while others provide a daily data cap that accrues each day; there are 39 daily‑cap options and 123 fixed‑cap options among the offerings.
