nextSIM eSIM Data Plans for Taiwan

nextSIM does not provide a truly unlimited data eSIM for Taiwan. All plans listed under “Unlimited” in the provider’s catalogue actually come with a fixed data allowance—ranging from 1GB up to 2GB per day—and, after the data limit is reached, the speed is reduced to 512kbps or 2000kbps.

If you need large data volumes without speed capping, nextSIM offers fixed‑data plans such as the 50GB and 100GB 30‑day options. These plans provide a high amount of high‑speed data, but they are capped and do not offer an unlimited data experience.

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.
