Simbye eSIM Data Plans for East Asia

Simbye does not offer an unlimited data eSIM plan for East Asia. The provider’s plans in this region all come with fixed data caps.

Simbye’s fixed‑data options include a 20GB plan valid for 90 days costing $55.00 USD, a 10GB plan valid for 30 days costing $30.00 USD, and a 5GB plan also valid for 30 days costing $20.00 USD. These plans provide tethering and cover China, Hong Kong, Japan, South Korea, Macau, and several other nearby countries. Choosing a fixed data plan can be more cost‑effective than a constantly capped unlimited plan, unless a traveler’s usage is exceptionally high.

Simbye does not offer any East Asia eSIM plans that provide a phone number or SMS capability. The provider only sells data‑only eSIMs that region. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Simbye offers two East‑Asia‑focused eSIM packages. The Asia plan covers China, Hong Kong, Japan, South Korea and Macau, while the Global139 plan adds Taiwan to that list; Mongolia is not covered by either of these plans.
