Simsima eSIM Data Plans for Taiwan

Simsima does not have a true unlimited data eSIM for Taiwan. Its “Unlimited” plans limit high‑speed data to 3GB per day; once that amount is reached the speed throttles to 1000kbps, which means the plan is not unlimited in the sense of unlimited high‑speed data.
Instead, Simsima offers fixed‑data plans that may be more cost‑effective for heavy users, such as a 100GB plan valid for 180 days or a 50GB plan valid for 90 days. These plans provide a single high‑speed data allowance without a daily cap or speed reduction.

Simsima does not provide eSIM plans for Taiwan that include a local phone number or SMS capability. Travelers can only purchase data‑only plans with this provider in Taiwan. However, popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for voice calls and text messages. Because some destinations block or restrict access to specific apps or VoIP services, travelers should confirm that the applications they rely on are available in Taiwan before buying a plan.

Simsima provides 9 single country data plans for Taiwan and 19 multi country plans that also include Taiwan coverage. The plans cover a data range of 1 GB to 100 GB and cost between about $3.91 and $84.53 USD. Some plans are priced by a fixed data amount usable for the full validity period, while others use a daily data cap that limits how much data can be consumed each day until the validity expires. This gives users a range of options depending on whether they prefer a set total data allocation or daily limits.
