Ohayu eSIM Data Plans for Taiwan

Ohayu does not provide a truly unlimited data plan for Taiwan. The plans labeled “Taiwan Unlimited” actually give 3 GB of high‑speed data per day and, once that daily limit is reached, the speed drops to 1000 kbps. Because the data is capped, these plans are not unlimited in the sense of unlimited high‑speed data usage.

Travelers can instead choose from Ohayu’s fixed‑data plans for Taiwan, such as the 50 GB plan valid for 90 days, priced at $74.79 USD, or the 20 GB plan valid for 90 days, priced at $30.49 USD. These plans offer a substantial amount of high‑speed data and include tethering, and may be more cost‑effective unless very heavy data consumption is required.

Ohayu does not provide an eSIM for Taiwan that includes a phone number or SMS capability. The only available options are data‑only plans. Travelers can still use internet‑based messaging and calls through VoIP services such as WhatsApp, Telegram, or iMessage over the data connection.

Ohayu lists 9 single‑country data plans that cover only Taiwan and 4 multi‑country plans that include Taiwan in their coverage. The available plans range in price from $8.49 to $74.79 and provide data caps from 2 GB up to 50 GB. Validity periods vary between 5 and 90 days. Some plans feature a fixed total data allocation, whereas others impose a daily data cap, allowing users to spread the data over the validity period rather than receiving a single lump sum.
