eSIM guide

The best travel eSIM for Indonesia (Bali)

Indonesia is the single biggest overseas destination for Australians, and Bali is most of that. It is also the destination where eSIM pricing diverges most sharply between providers — the same fortnight of data ranges from about $14 to $73.90 depending on who you buy from.

Holaflyno fixed-data plans

Holafly sells no fixed-data plans anywhere — its 30-day unlimited plan is $73.90, which is a different product and so is not plotted on the same scale.

Our pick for Bali

Nomad

For a typical two-week Bali trip, Nomad's 10GB/30 days at $19 or Saily's at $21.99 covers most people. Holafly's $50.50 for 15 days only makes sense if you genuinely cannot estimate your usage — and its 1GB/day hotspot cap makes it a poor choice if you're working from the villa.

What these caps mean in practice →

Which network you actually roam onto

An eSIM is a roaming agreement with a local carrier. In Bali, that means:

ProviderLocal network
HolaflyXL (Excelcom) and Telkomsel
SailyTelkomsel
NomadTelkomsel
AiraloConflicting — Airalo names 3 (Hutchison); esimdb lists XL Axiata or Indosat. Likely varies by package.
