eSimfly eSIM Data Plans for East Asia

eSimfly does not provide a truly unlimited high‑speed data eSIM for East Asia. All plans labeled “Asia Unlimited” give a fixed allowance of 1 GB per day; after that limit is reached the speed is reduced, although the exact throttled speed is not listed in the data.

For travelers who need more data without a daily cap, eSimfly offers larger fixed‑data plans. For example, the Asia 100 GB 180 days plan supplies 100 GB over six months, and the Asia 90 GB 365 days plan offers 90 GB for a full year. These plans are more expensive on a per‑gigabyte basis but avoid the daily 1 GB restriction and any speed throttling.

There are no East Asia eSIM plans with a phone number or SMS capability from eSimfly. All eSimfly eSIMs for that region are data‑only. Travelers wanting voice or messaging can still use VoIP services such as WhatsApp, Telegram, or iMessage, which operate over the internet connection provided by the data plan.

All seven East Asian countries on eSIMDB’s approved list are covered by eSimfly: China, Japan, Hong Kong, South Korea, Taiwan, Macau, and Mongolia. The standard “Asia” plan covers China, Hong Kong, Japan, South Korea and Taiwan; the “Asia (12 areas)” and “Asia (20 areas)” plans cover China, Japan, Hong Kong, South Korea, Macau and Taiwan; the “Asia‑20” plan covers China, Hong Kong, Japan, South Korea and Macau and also extends beyond the region; the “Asia Unlimited” plan covers Hong Kong, South Korea, Macau and Taiwan and likewise has additional coverage outside the region; and the “Discover Global” plans cover all seven East Asian countries (China, Hong Kong, Japan, South Korea, Mongolia, Macau, Taiwan) while also including a broader set of global destinations.
