AlpineSIM eSIM Data Plans for East Asia

AlpineSIM does not provide a truly unlimited data eSIM for East Asia. All of its so‑called “Unlimited Asia” plans are capped at 500MB, 1GB, 2GB, or 3GB of high‑speed data per day or per validity period, after which the speed is throttled (the throttled speed is not specified in the dataset). For travelers who need larger data amounts, AlpineSIM offers fixed‑data plans such as the 20GB eSIM valid for 30 days and the 50GB eSIM valid for 180 days, both covering China, Hong Kong, Japan, South Korea, Macau, Taiwan and additional countries. These fixed plans may be a more cost‑effective choice for heavy data users.

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.

AlpineSIM offers several eSIM products for East Asia. The plans titled AlpineSIM Unlimited Asia (20 areas) eSIM, AlpineSIM Unlimited Asia (12 areas) eSIM, AlpineSIM Asia 20 eSIM, AlpineSIM Unlimited Global, and AlpineSIM Global139 all list China, Hong Kong, Japan, South Korea, Macau and Taiwan as part of their coverage in the region. None of these plans include Mongolia.
