eSimfly eSIM Data Plans for East Asia

eSimfly does not offer a true unlimited data eSIM for East Asia. The plans that carry “Unlimited” in their name are limited to 1 GB of high‑speed data, after which the speed is reduced. If you need more data you can select one of eSimfly’s fixed‑data plans. For example, the Asia 100 GB plan is valid for 180 days, and the Asia 90 GB plan is valid for 365 days. These larger‑data options can be more cost effective unless you are an extremely heavy data user.

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 offers several eSIM plans that provide coverage for East Asian countries, including China, Hong Kong, Japan, South Korea, Taiwan, Macau, and, in the case of the Discover Global plan, Mongolia. The basic “Asia” plan and its variants – “Asia (12 areas)”, “Asia (20 areas)”, and “Asia‑20” – cover China, Hong Kong, Japan, South Korea, Macau and Taiwan. The “Asia Unlimited” and another “Asia” variant that list Hong Kong, South Korea, Macau and Taiwan provide the same core coverage without Japan. The “Discover Global” plan extends that list by adding Mongolia, while the “Global (120+ areas)” plan includes China, Hong Kong, Japan, South Korea, Macau and Taiwan and adds worldwide coverage beyond East Asia.
