yaySIM for East Asia FAQ
Does yaySIM offer unlimited data eSIM for East Asia?
yaySIM does not provide any unlimited data eSIM for East Asia. The current options for East Asia are fixed data plans with capped allowances, such as a 50GB plan valid for 180 days and a 20GB plan valid for 30 days. Travelers who need a large data allowance can choose one of these fixed plans, which may be more cost‑effective than a pay‑as‑you‑go approach unless they expect to use an exceptionally high amount of data.
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.
