Short answer
Skip expensive Australian roaming ($5–15 AUD/day). Get a BaliSIM Telkomsel eSIM before your flight — from $14.56 USD, active the moment you land in Bali.
Australians are one of the biggest visitor groups in Bali — and most arrive with the same question: should you use Australian roaming or buy a local Indonesian eSIM?
The short answer: a local BaliSIM eSIM is dramatically cheaper, faster, and easier. Australian roaming in Indonesia is surprisingly expensive for how close Bali is to Australia, and most travelers burn through their roaming allowance within days.
This guide covers everything Australian travelers need to know before flying to Bali: roaming costs from Telstra, Optus, and Vodafone Australia, whether your Australian phone works in Indonesia, which BaliSIM plan fits your trip, and how to set everything up before departure.

Australian Roaming in Bali vs a Local eSIM — The Real Cost
Indonesia is not included in Australian domestic mobile plans. International roaming charges apply the moment your plane lands in Bali.
| Australian carrier | Indonesia roaming cost | Notes |
|---|---|---|
| Telstra | $10 AUD/day | International Day Pass activates automatically |
| Optus | $5–10 AUD/day | Limited high-speed data before throttling |
| Vodafone AU | $5 AUD/day | Still expensive for trips longer than a week |
| Boost / Amaysim / Aldi Mobile | Limited or unavailable | Many MVNOs don't include Indonesia roaming |
| BaliSIM (local Indonesian eSIM) | from $14.56 USD total | Full trip coverage on Telkomsel Indonesia |
The math becomes obvious quickly. A typical 10-day Bali holiday using Telstra roaming costs around $100 AUD just for data. A BaliSIM eSIM costs a fraction of that — with better speeds and no daily activation fees.
Local Indonesian eSIMs also perform better because your phone connects directly to Indonesian towers instead of routing traffic through Australia. That means lower latency, faster Instagram uploads, smoother WhatsApp calls, and more reliable Google Maps.

Does Your Australian Phone Work in Bali?
Yes — almost every modern Australian phone works perfectly in Indonesia.
Network compatibility: Indonesia uses GSM/LTE/5G networks fully compatible with Australian devices. iPhones, Samsung Galaxy devices, Google Pixels, and most modern Android phones work immediately with Indonesian carriers.
Is your Australian phone unlocked? Phones purchased outright from Apple, JB Hi-Fi, Harvey Norman, or Officeworks are almost always unlocked. Phones purchased on Telstra, Optus, or Vodafone contracts may still be locked if they're relatively new. The easiest check: go to your phone settings and look for “Add eSIM” or “SIM Manager.”
eSIM compatibility by popular Australian phone models:
| Phone | eSIM support | Notes |
|---|---|---|
| iPhone 14, 15, 16 | ✓ Full eSIM | Works perfectly with BaliSIM |
| iPhone XS, XR, 11, 12, 13 | ✓ eSIM supported | Dual SIM supported |
| Samsung Galaxy S20–S24 | ✓ eSIM supported | Australian models support eSIM |
| Google Pixel 6–9 | ✓ eSIM supported | Excellent eSIM experience |
| Older Android phones | ✗ Maybe not | Check device settings first |
| Huawei devices | ✗ Usually no eSIM | Use physical SIM instead |
