AlpineSIM eSIM Data Plans for East Asia

AlpineSIM does not provide a truly unlimited data eSIM for East Asia. All East‑Asian plans listed in the database have a specific data cap, such as 50GB for a 180‑day period, 20GB for 30‑day or 90‑day periods, and a range of lower‑cap “Unlimited” designs that offer 500MB, 1GB, or 2GB of high‑speed data before the speed is throttled after the limit is reached. For travelers who need very large data allowances, fixed‑data plans like the 50GB 180‑day option or the 20GB 30‑day or 90‑day plans can be more cost‑effective than the capped “Unlimited” plans, which are designed for moderate usage and introduce reduced speed once the allocated quota is exhausted.

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.
