Saily eSIM Data Plans for East Asia

Saily does not provide a truly unlimited data eSIM for East Asia. Plans that carry “Unlimited” in the name, such as the Asia and Oceania UNLIMITED 5‑day and the Global UNLIMITED 30‑day offers, actually contain a fixed data allowance—5 GB per day for 5 days or 30 GB for 30 days, respectively. After the allocated data is used, the speed drops to a reduced throttled rate.

Travelers looking for a plan with no automatic throttling can choose from Saily’s fixed data plans, such as the Asia and Oceania 25 GB plan valid for 60 days or the Global 20 GB plan valid for 365 days. These plans give a set amount of high‑speed data for a set period and can be more cost‑effective for heavy data users staying in East Asia.

Saily does not provide East Asia eSIM plans that include a phone number or SMS capability. Travelers who purchase an East Asia eSIM from Saily will receive only a data‑only plan. However, they can still use common VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging, though some destinations may restrict certain apps. It is advisable to verify the accessibility of these services in the specific East Asian country before buying an eSIM from Saily.

Saily offers two eSIM plans that include coverage in East Asia. The Asia and Oceania plan covers China, Hong Kong, Japan, South Korea, Macau, and Taiwan. The Global plan also includes the same East Asian countries—China, Hong Kong, Japan, South Korea, Macau, and Taiwan—while extending service to many other regions worldwide.
