nextSIM eSIM Data Plans for East Asia

nextSIM does not provide truly unlimited data eSIM plans for East Asia. The plans named “Unlimited” in the catalog have fixed data caps of 1 GB or 2 GB and reduce speed to 512 kbps or 2000 kbps once the cap is reached, so high‑speed data is still limited.

Travelers who need larger data allowances can choose from fixed‑data plans, such as the 20 GB option that covers Hong Kong, South Korea, Macau, Taiwan plus nine additional countries for about $49.74 USD, or the 30 GB plan that covers China, Hong Kong, Japan, Macau, Mongolia, South Korea, Taiwan and 151 other countries for about $779.72 USD. These plans provide consistent high‑speed data up to their data limits.

nextSIM does not offer an East Asia eSIM with a phone number or SMS capability. Only data‑only plans are available from nextSIM for this region. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

nextSIM’s eSIM plans cover the seven East Asian countries of China, Hong Kong, Japan, Macau, South Korea, Taiwan and Mongolia. Multiple plan names provide coverage across this entire region, such as the eSIM ASIA + Australia Economy plan for South Korea, Hong Kong, Macau and Taiwan; the eSIM Unlimited Standard Asia plan for Hong Kong, Macau, South Korea and Taiwan; the eSIM Unlimited Standard Global plan for China, Hong Kong, Japan, Macau, South Korea and Taiwan; the eSIM GLOBAL Premium and eSIM ASIA and Middle East Premium plans for China, Hong Kong, Japan, Macau, South Korea, Taiwan and Mongolia; the eSIM GLOBAL Economy plan for South Korea, Hong Kong, Macau, Taiwan, China and Japan; and the eSIM Unlimited Plus Global plan for China, Hong Kong, Japan, Macau, South Korea and Taiwan (the second version covers China, Hong Kong, Japan and Macau).
