nextSIM eSIM Data Plans for Taiwan

NextSIM does not provide a truly unlimited data eSIM for Taiwan. All plans that include “Unlimited” in the name still carry a fixed data allowance, typically 1 GB or 2 GB per day, and when that limit is reached the connection speed is throttled to either 512 kbps or 2000 kbps. For travelers who need a larger data budget, nextSIM offers fixed‑data options such as the 100 GB 30‑day plan and the 50 GB 30‑day plan for Taiwan. These plans can be more cost‑effective for heavy data users compared with the “Unlimited” names, which actually apply a limited data cap before speed reduction.

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 a variety of data plans for travelers visiting Taiwan, with 34 single‑country options that provide data directly for Taiwan only and an additional 61 multi‑country plans that include Taiwan alongside other destinations. The available plans range from as low as $2.95 for a 1 GB data allocation to $1, 291.98 for a 100 GB package, with validity periods between one and thirty days. Plans are generally split into two key types: fixed‑data‑cap plans, where a set amount of data is delivered over the plan’s duration, and daily‑data‑cap plans, which allow a specified amount of data to be used each day. This mix gives users flexibility in choosing the plan size and usage pattern that best matches their travel needs.
