nextSIM eSIM Data Plans for Taiwan

No, nextSIM does not provide a genuinely unlimited data eSIM for Taiwan. The plans that carry “Unlimited” in the name actually contain a fixed amount of high‑speed data—typically 1 GB or 2 GB per day for the duration of the plan—and once that limit is reached the speed drops to a reduced rate (for example 512 kbps or 2000 kbps).

If a larger data allowance is needed, nextSIM offers fixed‑data options such as the 50 GB or 100 GB plans that are valid for 30 days. These plans give the specified high‑speed data without the daily throttling that applies to the “Unlimited” plans. Choosing a fixed‑data plan can be more cost‑effective for travelers who anticipate moderate to heavy use.

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.
