JamboSim eSIM Data Plans for Taiwan

JamboSim’s “Unlimited” eSIM plans for Taiwan do not provide unrestricted high‑speed data. Each plan limits the user to 3 GB per day, and once that quota is reached the speed is throttled to 1 000 kbps. Because of this daily cap, the plans are not truly unlimited in the sense of offering unlimited high‑speed usage.

If a traveler needs more data without the daily restriction, JamboSim offers several fixed‑data options. For example, a 20 GB plan that lasts 30 days or a 100 GB plan that lasts 180 days give a larger overall allowance and can be more cost‑effective for heavier data users. These fixed‑data plans avoid the daily limit and speed reduction that characterise the “Unlimited” products.

JamboSim does not provide Taiwan eSIM plans that include a phone number or SMS capability. All of JamboSim’s Taiwan eSIMs are data‑only, so travelers must rely on VoIP applications like WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection.

JamboSim provides 12 single‑country data plans that cover Taiwan and 33 multi‑country plans that include Taiwan in their coverage. The plans are available across a price spectrum from $1.99 to $99.99 and offer data caps ranging from 200 MB up to 100 GB. Within this suite, 33 plans are based on a fixed data amount—meaning a set total quantity of data that is available for the validity period—while 12 plans employ a daily data cap, allocating a specific amount of data each day during the validity window.
