nextSIM eSIM Data Plans for East Asia

nextSIM does not provide a truly unlimited data eSIM for East Asia. All plans listed under the “Unlimited” name actually have a fixed data allowance—either 1GB or 2GB per day—which is then followed by a reduced speed of 512kbps or 2000kbps after the limit is reached. When high‑speed data is required beyond that allowance, the network throttles the user down to the reduced speed specified in each plan’s description.

Travelers who need larger, unthrottled data packages can choose from the fixed data plans that nextSIM offers. For example, a 20GB 30‑day plan costs about $50.04 USD and a 30GB 30‑day premium plan is priced at roughly $750.82 USD. These fixed‑data options can be more cost effective for those who expect heavy data usage, compared to a plan that claims “unlimited” but actually includes a cap and speed reduction.

nextSIM does not provide East Asia eSIM plans that include a phone number or SMS capability. Only data‑only eSIM options are available from this provider for East Asia. Travelers who need to communicate can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection; however, some destinations in East Asia may block or restrict specific apps or VoIP services. It is advisable to verify that the messaging or calling apps you rely on are accessible in the intended locations before purchasing a plan.

The eSIM Asia Standard and Economy plans cover Hong Kong, South Korea, Macau, and Taiwan. The eSIM Global Standard, Unlimited Standard, and Unlimited Plus Standard plans cover China, Hong Kong, Japan, South Korea, Macau, and Taiwan. The eSIM Global Premium and ASIA and Middle East Premium plans additionally cover Mongolia.
