Saily eSIM Data Plans for East Asia

Saily does not provide a truly unlimited high‑speed data plan for East Asia. The plans marked “UNLIMITED” actually allocate a set amount of data—5 GB per day or 30 GB per month—and reduce speed to 1 kbps or 1024 kbps once that amount is exceeded. Travelers who need a large amount of data might consider Saily’s fixed data plans, such as Asia and Oceania 25GB for 60 days at $48.99 or Global 20GB for 365 days at $66.99, which offer higher data allowances and can be more cost‑effective unless a user requires continuous speed without limits.

Saily does not provide East Asia eSIM plans that include a phone number or SMS capability. Travelers will only find data‑only offerings with no incoming or outgoing voice or text messaging services from this provider in East Asia.

Because of this limitation, users may rely on VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection and allow calls and messaging without a local phone number or SMS support.

Saily offers coverage in East Asia through its Asia and Oceania plan, which includes China, Hong Kong, Japan, South Korea, Macau, and Taiwan; the Global plan also lists the same East‑Asian countries as part of its coverage area.
