nextSIM eSIM Data Plans for East Asia

nextSIM does not provide a truly unlimited data eSIM for East Asia. The plans listed under its “Unlimited” category all contain a fixed high‑speed data allowance, such as 1GB per day, after which the speed is reduced to 512kbps or 2000kbps. Because the data cap is still present, the term “Unlimited” only refers to the name. Travelers who require higher data volumes can select from nextSIM’s fixed‑data plans, for example the eSIM Asia 20GB 30Days Standard plan, which offers 20GB of 5G data for 30 days at a lower price. These fixed‑data options may be more cost‑effective for users who are heavy data consumers.

nextSIM does not provide East Asia eSIM plans that include a local phone number or SMS capability. Their East Asia offerings are data‑only. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communication.

NextSIM’s eSIM plans that serve East Asia cover the following countries: China, Japan, Hong Kong, South Korea, Taiwan, Macau, and Mongolia. Plans are grouped by the set of East‑Asian countries they include: the eSIM Asia Standard and Economy plans cover Hong Kong, South Korea, Macau, and Taiwan; the eSIM Global Standard, eSIM Global Unlimited Standard, and both editions of eSIM Global Unlimited Plus Standard cover China, Hong Kong, Japan, South Korea, Macau, and Taiwan; and the eSIM GLOBAL Premium and eSIM ASIA and Middle East Premium plans cover China, Hong Kong, Japan, South Korea, Mongolia, Macau, and Taiwan. All plans that list these regions also include additional global destinations, but the above countries are those within East Asia that are guaranteed coverage.
