JamboSim eSIM Data Plans for Taiwan

JamboSim does not provide a high‑speed, truly unlimited eSIM plan for Taiwan.
All plans marketed as “Unlimited” give only 3GB of 5G‑class data each day; once that limit is reached the speed drops to a reduced 1000kbps.

For travellers who need a larger unthrottled allowance, JamboSim offers fixed‑data eSIMs such as 20GB for 30 days, 50GB for 90 days, and 100GB for 180 days, all covering Taiwan. These plans give the same maximum speed throughout their validity and can be more cost‑effective than the daily‑limited “Unlimited” options for heavy data users.

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.
