Ubigi eSIM Data Plans for East Asia

Ubigi offers three plans that include East Asian coverage. The ASIA plan covers Mongolia, China, Japan, Hong Kong, Taiwan, Macau and South Korea. The WORLD plan also covers Taiwan, China, Mongolia, Macau, South Korea, Hong Kong and Japan. The BEST ASIA plan covers Hong Kong, Japan, Taiwan, Macau and South Korea. In total, Ubigi’s eSIM plans cover the following East Asian countries: Mongolia, China, Japan, Hong Kong, Taiwan, Macau and South Korea.

Ubigi does not provide a truly unlimited data eSIM for East Asia. The current catalog only lists fixed‑data offers that cap usage at a specified amount.

Travelers who need a large amount of data can choose from the available fixed plans. For example, the BEST ASIA plan provides 60GB for 900 days at $78.00 USD, and the WORLD plan offers 60GB per month for 30 days at $240.00 USD, while the 50GB 30‑day variation costs $188.00 USD. These options cover major East Asian countries such as Hong Kong, Japan, Taiwan, Macau, and South Korea, plus many additional destinations. Selecting a fixed‑data plan can be more cost‑effective unless very heavy data usage is expected, in which case an unlimited plan would be preferable—though such a plan is not currently available from Ubigi.
