nextSIM eSIM Data Plans for Taiwan

nextSIM does not provide a truly unlimited data eSIM for Taiwan. The plans labelled “Unlimited” in the catalogue actually include a fixed amount of high‑speed data—1GB or 2GB per day—before the speed is reduced to 512kbps or 2000kbps.

If unlimited data is required, nextSIM offers fixed large‑data plans instead, such as the 30GB Premium plan valid for 30 days at $774.92, the 40GB Premium plan at $1,033.22, the 50GB Premium plan at $1,291.53, or the 20GB Economy plan at $49.25. These alternatives provide substantial data allowances that may be more cost‑effective for heavy users compared to the nominal “Unlimited” options.

nextSIM does not offer a Taiwan eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for Taiwan. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging.

NextSIM offers 20 single‑country plans and 35 multi‑country plans for travelers in Taiwan. The plans cover a price spectrum from about $4.13 to $1,291.53 and a data cap range that spans from 1 GB to 50 GB per validity period, which can be as short as one day or as long as thirty days. Some plans apply a daily data cap—meaning the allotted data is refreshed each day—while others use a fixed data amount that is available for the entire validity period without renewal. The combination of single‑country and multi‑country options provides flexibility for both short‑term visits and longer stays that might include multiple destinations.
