JamboSim eSIM Data Plans for Indonesia

JamboSim does not provide a truly unlimited data eSIM for Indonesia. All of its plans marketed as “Unlimited” actually offer 3 GB per day of high‑speed data and include a reduced speed of 1000 kbps once that daily limit is reached. Because the data cap is fixed, these plans are not unlimited in the sense of unmetered high‑speed access.

Instead, JamboSim sells fixed‑data plans that can be more cost effective for most travelers. For example, a 20 GB plan valid for 30 days costs $12.99, while a larger 100 GB plan valid for 180 days costs $71.99. These examples illustrate the range of high‑data‑allowance options available, but they represent only a subset of the full list of plans offered by JamboSim.

JamboSim does not provide any eSIM plans for Indonesia that include a phone number or SMS capability. All offers from the provider for this destination are data‑only, meaning there is no local dialing code, inbound or outbound voice, or SMS service included.

Travelers who need to make voice calls or send messages can rely on internet‑based applications such as WhatsApp, Telegram, or iMessage. These apps work over the data connection supplied by the eSIM and allow voice and text communication without a traditional phone number.

JamboSim offers 12 single‑country plans and 33 multi‑country plans that include coverage for Indonesia. Single‑country plans provide data caps from 200 MB to 100 GB and are priced between $1.99 and $99.99. Multi‑country bundles have the same price and data ranges but extend coverage beyond Indonesia. Some plans are structured as daily data caps—12 options that refresh the allowance each day—whereas the remaining 33 plans are fixed‑data caps that allow the total amount to be used over the validity period.
