nextSIM eSIM Data Plans for Taiwan

nextSIM does not provide a truly unlimited high‑speed data eSIM for Taiwan. All plans labeled “Unlimited” deliver only 1GB or 2GB of high‑speed data per day and, after the cap is reached, the speed is reduced to 512kbps or 2000kbps.

Travelers who need no throttling can choose a fixed‑data plan instead. For example, the eSIM Taiwan 100GB 30Days Economy plan costs $87.12 USD and offers a steady 100GB of data for 30 days, while the eSIM Taiwan 50GB 30Days Standard plan costs $83.82 USD and provides 50GB without any speed reduction. These fixed‑amount plans can be more cost‑effective for heavy data users.

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 provides 43 single‑country plans and 62 multi‑country plans that include Taiwan. The plans vary widely in price—from $2.98 to $1, 316.18—and data allowance—from 1 GB up to 100 GB. Some options are “fixed data amount” plans with a set data cap that lasts the plan’s validity period, while others are “daily data cap” plans that reset each day and are counted among the 38 daily‑cap options. A few plans apply reduced speeds (512 kbps or 2000 kbps).
