nextSIM eSIM Data Plans for East Asia

nextSIM does not provide a truly unlimited data eSIM for East Asia; all plans that use the “Unlimited” name have a fixed amount of high‑speed data, after which the speed is throttled. For example, the eSIM Asia Unlimited 10Days Standard plan offers 1GB/day of 5G data for 10 days before reducing speed to 512kbps, while the eSIM Asia Unlimited Plus 10Days Standard plan gives 2GB/day of 5G data for the same period and reduces to 2000kbps once the daily limit is reached. Other plans in the same category follow similar structures, with daily caps of 1GB or 2GB and reduced speeds of 512kbps or 2000kbps. Fixed data plans, such as the eSIM Asia 20GB 30Days Standard, are available as alternatives and may be more cost‑effective for travelers who need larger data allowances without the speed reduction that comes with the “Unlimited” name.

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 Global Standard, Unlimited Standard, and Unlimited Plus Standard plans cover China, Hong Kong, Japan, South Korea, Macau, and Taiwan.
