The pricing ladder spans from 1GB at $3.99 ($3.99/GB) to 20GB at $31.49 ($1.57/GB). Best per-GB value sits at 20GB for $31.49 ($1.57/GB), our recommended tier for most Indonesia travelers. Holafly adds an unlimited daily option from $2.99/day, which suits heavy data users on trips of 5+ days. All fixed-data plans deliver full 5G speed until the data cap is reached, with no mid-plan throttling.

Carrier Partnerships
Indonesia operates 3 mobile networks: Telkomsel (5G), XL (4G), Smartfren (4G). Telkomsel serves as the primary routing partner for travel eSIMs in this market. All five ranked providers maintain routing agreements with Telkomsel. Some providers additionally route through XL as a fallback when Telkomsel's signal weakens.
Telkomsel publishes 5G across Indonesia, and every ranked provider attaches to it rather than to a network of its own. With 3 networks accepting eSIM roaming, Indonesia offers strong carrier diversity. Signal handoffs between Telkomsel, XL, and Smartfren keep connections stable across geographic boundaries.
Provider routing varies subtly in Indonesia. Airalo and Saily default to Telkomsel, while Holafly may route through XL in specific regions. Nomad uses Telkomsel exclusively. These routing differences show up in rural reach rather than in the plan terms.
