Zwitchy eSIM Data Plans for East Asia

Zwitchy does not provide a truly unlimited data eSIM for East Asia. The plans that carry “Unlimited” in their name offer a fixed daily allowance of 1 GB, and once that amount is exhausted the speed is throttled to 1000 kbps. Travelers who require more data without speed reduction can opt for fixed data plans that give larger bundles, such as the 50 GB 30 days plan priced at $87.50 USD or the 30 GB 30 days plan priced at $55.00 USD. Both plans provide 5G coverage across China, Hong Kong, Japan, South Korea, Macau, Taiwan and additional East Asian countries.

Zwitchy does not offer East Asia eSIM plans that include a phone number or SMS capability. All Zwitchy eSIMs for East Asia are data‑only; they provide high‑speed internet rather than traditional voice or text services.

Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations in East Asia may block or restrict certain apps or VoIP services, so it is advisable to check whether the apps you rely on are accessible before purchasing an eSIM from Zwitchy.

Zwitchy’s Asia plan covers China, Hong Kong, Japan, South Korea, Macau, and Taiwan, while the Global plan adds Mongolia to that same core group of East Asian countries.
