AeroSims eSIM Data Plans for East Asia

AeroSims does not provide an unlimited data eSIM for East Asia. All its plans for the region are fixed data bundles, with the highest offering 50 GB for 180 days.

For travelers who need large data allowances, AeroSims offers a 50 GB 180‑day plan covering China, Hong Kong, Japan, South Korea, Macau, and additional countries, and a 20 GB 30‑day plan that covers the same core markets plus Taiwan. Because these are fixed plans, they can be more cost‑effective for most users, while frequent top‑ups allow more flexibility for heavy data consumption.

AeroSims does not offer an East Asia eSIM that includes a phone number or SMS capability; all plans for the region are data‑only. Travelers who need local calls or text messaging can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, though some destinations may block or limit certain VoIP apps, so it is advisable to verify that the apps you rely on are available in East Asia before purchasing a plan.

Japan, China, Hong Kong, South Korea, Macau, and Taiwan are the East Asian countries covered by AeroSims’s eSIM plans. The Asia (12 Countries) plan offers coverage in all six of these countries. The Asia (20 Countries) plan likewise includes Japan, China, Hong Kong, South Korea, and Macau, and the Asia (19 Countries) plan covers Japan, China, Hong Kong, South Korea, and Taiwan. Both the Global (115 + Countries) and Global (125 + Countries) plans also list these same six East Asian countries among their coverage areas.
