We currently offer 600+ plans across 38+ destinations and regions — single-country, multi-country, and regional bundles.

shibaSIM for East Asia FAQ
Does shibaSIM offer unlimited data eSIM for East Asia?
shibaSIM does not provide an unlimited data eSIM for East Asia. All of its plans for the region have a hard data cap, such as 100GB or 50GB, and a fixed validity period ranging from 3 days to 30 days.
Travelers who need a large amount of data can choose from shibaSIM’s fixed data plans. For example, the Greater China 100GB for 30 days plan offers a substantial data allowance for a month, and the Greater China 100GB for 15 days plan provides a similar amount for a shorter period. These fixed data plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from a truly unlimited option.
Does shibaSIM offer East Asia eSIM with phone number and SMS?
shibaSIM does not offer any East Asia eSIM plans that include a local phone number or SMS capability. All available plans from shibaSIM for East Asia are data‑only, which means travelers will not receive an inbound or outbound voice or text service.
Travelers who need to communicate while abroad can rely on data‑connected VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages. However, some destinations may restrict or block certain VoIP services, so it is advisable to confirm that the apps you rely on are accessible in the specific East Asian country before purchasing a shibaSIM plan.
