TraveleSIM.CH eSIM Data Plans for East Asia

TraveleSIM.CH does not provide any unlimited data eSIM for East Asia. All of its East‑Asia offerings have a fixed data cap.

For travelers who need a larger data allowance, TraveleSIM.CH offers a 50GB plan valid for 180 days and several 20GB plans valid for 30 days. These fixed‑data options can be more economical than a hypothetical unlimited plan, unless a user expects very heavy data usage.

TraveleSIM.CH does not offer any East Asia eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for that region. Travelers wishing to use voice or messaging apps can do so over the data connection with VoIP services such as WhatsApp, Telegram or iMessage, but service availability may vary in some destinations, so it is advisable to confirm that the chosen apps work in East Asia before purchasing a plan.

TraveleSIM.CH offers several eSIM plans that cover China, Hong Kong, Japan, South Korea, Macau and Taiwan in East Asia. For example, the Asia (12 areas) plan and the Asia (20 areas) plan include these countries, while the Global (120+ areas) and Sim Card for Global139 plans also list them as part of the East Asian coverage. These plans provide additional coverage outside the region, but the East Asian countries remain consistent across all offerings.
