YeeSiM eSIM Data Plans for East Asia

YeeSiM does not provide an unlimited data eSIM for East Asia. The provider offers fixed‑data plans such as a 90GB option valid for 365 days at $193.00 USD and a 50GB option valid for 365 days at $136.00 USD, both covering major East Asian countries including China, Hong Kong, Japan, South Korea, Macau, and Taiwan. Choosing a fixed‑data plan can be more cost‑effective for most travelers unless the user is an extremely heavy data consumer.

YeeSiM does not provide East Asia eSIM plans that include a phone number or SMS capability. Their offering consists solely of data‑only eSIM solutions. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging without requiring a local phone number or SMS.

The Asia (20 areas) eSIM plan covers China, Hong Kong, Japan, South Korea and Macau, while the Global (120+ areas) eSIM and Global (130+ areas) eSIM plans cover China, Hong Kong, Japan, South Korea, Macau and Taiwan; the Asia (12 areas) eSIM plan similarly covers China, Hong Kong, Japan, South Korea, Macau and Taiwan—no other East Asian country such as Mongolia is included in YeeSiM’s eSIM offerings.
