AlpineSIM eSIM Data Plans for East Asia

AlpineSIM does not provide a truly unlimited data eSIM plan for East Asia. The plans that carry the word “Unlimited” in their name actually include a fixed data allowance per day—for example, 500MB/day, 1GB/day, or 2GB/day. When the daily limit is exceeded the data speed is throttled, so the plan is not truly unlimited in the sense of high‑speed data without limits.

If an unlimited‑type plan is required, travelers can instead choose one of AlpineSIM’s fixed‑data plans. For instance, the AlpineSIM Asia‑20 eSIM offers 20 GB for 30 days, or a larger 50 GB plan that lasts 180 days. These fixed data plans give a set high‑speed data allowance for each validity period and are often more cost‑effective, especially for users who need a predictable amount of data while visiting China, Hong Kong, Japan, South Korea, Macau, Taiwan, and other East Asian destinations.

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.
