nextSIM eSIM Data Plans for Taiwan

nextSIM does not provide a truly unlimited high‑speed data eSIM for Taiwan. All plans that carry “Unlimited” in their name actually offer a fixed data limit—such as 1 GB or 2 GB—with a speed reduction to 512 kbps or 2000 kbps once the limit is reached. Travelers who need unrestricted high‑speed data can instead choose from large‑cap fixed data plans, for example the 50 GB or 100 GB 30‑day plans, which provide continuous 5G speed until the data allowance is exhausted. Fixed data plans often offer better value for heavy data users compared to the limited‑speed unlimited names.

No, nextSIM does not provide a mobile phone number or SMS service for its Taiwan eSIM plans; only data‑only eSIMs are available. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps work in Taiwan before purchasing, as some destinations may block or restrict such services.

nextSIM lists 43 single‑country plans and 58 multi‑country plans specifically for Taiwan, covering a price range between $1.85 and $1, 258.60 and data caps from 1 GB up to 100 GB. The catalogue includes both fixed‑data‑cap options—where the amount of data is set for the life of the plan—and daily‑cap plans, which limit the amount of data that can be used each day. These provisions give travelers flexibility, whether they prefer a straightforward data allotment or a daily‑controlled usage pattern.
