Yesim does provide unlimited‑data eSIM plans that work in Indonesia. For travellers staying only in Indonesia, the company offers packages ranging from 1 day at $5.80 USD to 30 days at $49.91 USD, all of which include tethering and are marked as unlimited. In addition, South East Asia packages that cover Indonesia are available from 1 day at $8.13 USD to 30 days at $55.72 USD. These plans note that speeds may be throttled after heavy usage under a Fair Usage Policy, so normal speed is typically capped at the network’s maximum (5G, 4G, 3G). If you are concerned about potential speed restrictions, it is advisable to contact Yesim directly to confirm the Fair Usage limits and the amount of data that remains at full speed.
