BlueSky eSIM does not provide truly unlimited high‑speed data for East Asia. The plans titled “Unlimited Data” give a data cap of 3 GB per day; when that limit is reached the speed is reduced to 1000 kbps, so the plans are not unlimited in the strict sense.
Instead, BlueSky eSIM offers fixed‑data alternatives that may be more suitable. A 100 GB package valid for 180 days costs $89, and a 20 GB plan for 30 days is priced at $39. These plans provide a flat high‑speed data allowance and can be more cost‑effective unless a traveler requires continuous high‑speed usage beyond the 3 GB daily limit.
BlueSky eSIM does not provide East Asia eSIM plans that include a phone number or SMS capability.
Only data‑only eSIMs are offered for East Asia; travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.
BlueSky eSIM offers several eSIM plans that include coverage in East Asian countries. The “🔷 [5G] Worldwide (201 countries)” plan lists China, Hong Kong, Japan, South Korea, Macau, Taiwan, and Mongolia as covered East Asian destinations. The “✈️ [5G] Asia (18 countries)” plan covers China, Hong Kong, Japan, South Korea, Macau, and Taiwan. The “🔷 [5G] Worldwide (173 countries) + Calls & SMS” plan covers China, Hong Kong, Japan, South Korea, and Macau.
