yaySIM for East Asia FAQ
Does yaySIM offer unlimited data eSIM for East Asia?
No, yaySIM does not have an unlimited data eSIM for East Asia. All available plans are fixed‑data bundles. For example, the AS‑20_50_180 plan gives 50GB of data valid for 180 days, and the AS‑14_20_30 plan offers 20GB for 30 days. Because these plans have hard limits, they may be more cost‑effective for most travelers, while an extremely heavy data user would need to purchase additional bundles or a different provider.
Does yaySIM offer East Asia eSIM with phone number and SMS?
yaySIM does not offer East Asia eSIM plans that include a phone number or SMS capability. Travelers looking for voice or text services over the internet can use popular VoIP apps such as WhatsApp, Telegram, or iMessage, but they should verify that these services are accessible in the specific East Asian destinations they plan to visit.
What countries are covered by yaySIM's eSIM plans in East Asia?
China, Hong Kong, Japan, South Korea, Macau, and Taiwan are the East Asian countries covered by yaySIM’s eSIM plans. All of the provider’s plans—AS‑21_0.5_Daily, AS‑12_0.5_Daily, AS‑20_1_7, GL‑120_1_Daily, GL‑120_1_7, and GL‑139_1_7—include these countries in their East Asian coverage, and none of the plans cover Mongolia.
