nextSIM eSIM Data Plans for Taiwan

No, nextSIM does not provide a truly unlimited data eSIM for Taiwan. All plans that carry the “Unlimited” name actually limit high‑speed data to 1GB or 2GB; after that amount the speed drops to 512kbps or 2000kbps, depending on the package.

For travelers who need larger data allowances, nextSIM offers fixed‑capacity plans instead. For example, the eSIM Taiwan 50GB 30Days Economy plan gives 50GB of high‑speed data for 30 days, and the eSIM Taiwan 100GB 30Days Economy plan provides 100GB for the same period. These fixed‑data options can be more cost‑effective unless a user requires extremely heavy data usage.

NextSIM does not offer a Taiwan eSIM plan that includes a local phone number or SMS capability. The provider only sells data‑only eSIMs for Taiwan, so travelers without a phone number will need to rely on data‑based applications for communication. Popular VoIP apps such as WhatsApp, Telegram and iMessage work over the data connection and can be used for calls and messaging even though traditional SMS and voice calls to and from phone numbers are not supported.

nextSIM offers 43 single‑country plans and 62 multi‑country plans that include Taiwan.
The single‑country plans are priced from roughly $2.92 to about $125.00, while the multi‑country variants range from roughly $5.00 to more than $1, 200.00.
All plans provide data caps between 1 GB and 100 GB and validity periods of 1 to 30 days.
Some plans are set up with a fixed data quantity, whereas others cap usage on a daily basis, allowing travelers to choose a rate that best matches their consumption pattern.
