Billion Connect eSIM Data Plans for East Asia

Billion Connect provides unlimited data eSIM plans that cover East Asia, including China, Japan, South Korea, Macau, Taiwan and 15 additional countries. The unlimited plans start at $2.53 for a 1‑day validity and increase up to $46.04 for a 30‑day validity, with the price scaling proportionally with the duration. While the data allowance is unlimited, normal speeds may be throttled after heavy usage, so travelers who are concerned about potential speed restrictions should contact Billion Connect to confirm whether a Fair Usage Policy applies and what the typical data available at normal speed is.

Billion Connect does not provide an East Asia eSIM plan with a phone number or the ability to send or receive SMS messages. The only plans available from this provider for East Asia are data‑only, so travelers must use data‑based VoIP services such as WhatsApp, Telegram or iMessage for calls and messaging.

Billion Connect offers several eSIM plans that cover East Asia. The Global eSIM [20 Regions] /Day and Asia eSIM [9 Regions] plans both include China, Japan, South Korea, Macau and Taiwan, while the Global eSIM [87 Regions] plan covers Japan, South Korea, Macau and Taiwan. No available plan includes Hong Kong or Mongolia, which are not part of the covered nations in this region.
