No, yaySIM does not provide an unlimited data eSIM plan for Indonesia. Instead, yaySIM offers fixed data plans in which a set amount of data must be used within a specified validity period. For example, there are 50 GB plans that are valid for 30 days or 180 days, and a 20 GB plan that is valid for 30 days. Choosing a fixed data plan can be more cost‑effective for typical travelers, unless the user plans to consume very high amounts of data, at which point an unlimited plan from another provider might be worth considering.
yaySIM does not provide eSIM plans for Indonesia that include a phone number or SMS capability, offering only data‑only options.
Travelers who require voice or messaging can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection; however, some destinations may block or restrict these services, so it is advisable to confirm that the apps needed are accessible in Indonesia before purchasing.
The latest catalog shows that yaySIM lists 25 single‑country plans that cover Indonesia alone and 57 multi‑country plans that include Indonesia along with other destinations. These plans span a price range of about $2.16 to $131.91, data caps from 102 MB up to 50 GB, and validity periods from one day up to a full year.
