4S eSIM eSIM Data Plans for Taiwan

4S eSIM does not provide a truly unlimited data eSIM for Taiwan. All plans listed under the “Unlimited” name have a hard data cap (for example, 10 GB or 50 GB) and, once the cap is reached, the speed is throttled to 1000 kbps. Travelers who need more long‑term data can choose from the fixed‑data plans, such as the 30 GB bundle valid for 15 days or the 50 GB bundle valid for 5 days, which offer larger data allowances at a single price without a speed reduction after the initial cap. These fixed data plans are generally more cost‑effective for consistent data usage in Taiwan.

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.
