AlpineSIM eSIM Data Plans for East Asia

AlpineSIM does not provide a truly unlimited high‑speed data eSIM for East Asia. The plans labelled “Unlimited Asia” offer fixed daily allowances such as 500 MB, 1 GB or 2 GB; after those limits are reached the speed is reduced.

Travelers who need large data volumes can choose from fixed data plans instead. An example is the AlpineSIM Asia‑20 eSIM – 50 GB valid for 180 days, and another is AlpineSIM Asia‑20 eSIM – 20 GB valid for 30 days. These fixed‑data options may be more cost‑effective for most users.

AlpineSIM does not provide East Asia eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIM options for the region. Travelers who need to make calls and send messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection instead.

AlpineSIM’s eSIM plans that cover East Asia include China, Hong Kong, Japan, South Korea, Macau, and Taiwan. For example, the AlpineSIM Unlimited Asia (20 areas) eSIM lists all six of those countries and then expands to numerous other regions worldwide, while the AlpineSIM Unlimited Asia (12 areas) eSIM covers the same East Asian countries and a smaller set of additional Asian markets. The AlpineSIM Asia‑20 eSIM also includes China, Hong Kong, Japan, South Korea, Macau and Taiwan but limits its scope to those six without the broader global coverage that the Unlimited Global and Global139 eSIMs provide. All of AlpineSIM’s global plans—AlpineSIM Unlimited Global and AlpineSIM Global139—specify China, Hong Kong, Japan, South Korea, Macau, and Taiwan among their core East Asian areas before listing many other countries beyond that region.
