AlpineSIM eSIM Data Plans for East Asia

AlpineSIM does not provide an unlimited data eSIM for East Asia. Instead, the provider offers fixed data plans with defined data caps. One example is a 50GB plan that is valid for 180 days, and another example is a 20GB plan that is valid for 30 days. Choosing a fixed data plan can be more cost–effective if a traveler’s data usage is moderate rather than extremely heavy.

AlpineSIM does not offer any East Asia eSIM that includes a local phone number or the ability to send SMS. The provider only supplies data‑only eSIMs for that region. Travelers who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is advisable to verify that the apps they depend on are accessible in East Asia before purchasing, as some destinations may block or restrict specific services.

The AlpineSIM plans that serve East Asia cover Japan, China, Hong Kong, South Korea, Taiwan and Macau. AlpineSIM Unlimited Asia (20 areas) includes all five of those except Macau, while AlpineSIM Unlimited Asia (12 areas) expands the coverage to include Macau as well; AlpineSIM Asia‑20 likewise lists China, Hong Kong, Japan, South Korea and Macau. The global offerings—AlpineSIM Unlimited Global and AlpineSIM Global139—both list China, Hong Kong, Japan, South Korea and Taiwan as part of their East Asian portfolio while providing access to additional regions beyond East Asia.
