Saily eSIM Data Plans for East Asia

Saily does not provide a truly unlimited high‑speed eSIM plan for East Asia. The only plan that carries “UNLIMITED” in its name, the Global UNLIMITED 30 days plan, actually offers 30GB of high‑speed data and automatically reduces speed to 1024kbps once the 30GB threshold is reached.

Saily’s alternative is a selection of fixed‑data plans. For example, the Asia and Oceania 50GB plan is valid for 90 days and the Asia and Oceania 100GB plan is valid for 180 days. These plans give travelers a larger high‑speed allowance than the 30GB option, and may be more cost effective for users who need substantial data without the bandwidth throttling that follows 30GB on the UNLIMITED name plan.

Saily does not provide eSIM plans with a phone number or SMS capability for East Asia. The provider’s lineup in this region consists solely of data‑only eSIMs.

Because a local phone number is not included, travelers cannot receive SMS messages or make voice calls through the SIM. However, popular Internet‑based messaging and calling services such as WhatsApp, Telegram, and iMessage will work over the data connection, allowing communication without a traditional phone number.

Saily’s eSIM offerings cover the following countries in East Asia: Japan, China, Hong Kong, South Korea, Taiwan, and Macau. These six nations are part of the Asia and Oceania plan and are also featured in the Global and Global Unlimited plans. While the Global tiers extend to many other regions worldwide, the East Asian coverage remains consistent across all of Saily’s available plans, and Mongolia is not included in the dataset.
