eSimfly eSIM Data Plans for East Asia

eSimfly does not provide a truly unlimited high‑speed eSIM plan for East Asia. The only “unlimited” names in its catalog actually contain a 1GB data cap, after which speed is reduced. Travelers looking for unlimited data must instead choose one of eSimfly’s fixed‑data offerings. For example, the Asia 100 GB 180‑days plan gives 100 GB of high‑speed data for three months, while the Asia 90 GB 365‑days plan supplies 90 GB for a full year. These fixed plans are available across China, Hong Kong, Japan, South Korea, Macau, and Taiwan, plus additional neighboring countries. Selecting a fixed‑data plan can be more cost‑effective unless a user expects to consume large amounts of data beyond the allocated allowance.

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.

eSimfly’s eSIM plans that focus on East Asia cover a consistent set of territories. The primary “Asia” family of plans—under labels such as Asia, Asia (12 areas), Asia (20 areas) and Asia‑20—include China, Hong Kong, Japan, South Korea, Macau and Taiwan. A subset of plans, namely Asia Unlimited and a variant of the basic Asia plan that lists only Hong Kong, South Korea, Macau and Taiwan, provide coverage limited to those four regions. The “Discover Global” plan extends the East Asian coverage to also encompass Mongolia in addition to the standard list of China, Hong Kong, Japan, South Korea, Macau and Taiwan. Thus every eSimfly plan offers connectivity across Hong Kong, South Korea, Macau and Taiwan, almost all of them include China and Japan, and only the Discover Global option adds Mongolia.
