These are assumed budgets, not average Bali usage. Maps and villa messages are a different data habit from nightly video calls and sending every holiday clip before dinner.
Use your dates and habits in the existing planner
The planner above takes arrival/departure dates, travel style and whether you need hotspot. It gives an estimated data range and an available plan match when it can. Put the full Indonesia stay into it, including other Indonesian stops where you'll need data.
If no match is available, compare the fixed options below or email hello@thesimshop.com.au with the dates and essential requirements. The estimate doesn't establish reception at a particular villa or guarantee hotspot performance.
Two budgets with the spare amount already counted
For a shorter stay, imagine four days of everyday phone use with a chosen 0.4GB daily budget and 0.4GB spare. That comes to 2GB, fitting our 3GB/30-day Indonesia plan at A$9.95. A longer, busier fortnight budgeted at 0.6GB daily plus 1.6GB spare reaches 10GB, matching our 10GB/30-day plan at A$17.95. These are assumptions to adjust, rather than promises about what your apps will use.
| Assumed trip | Calculation | Total budget | Fixed-plan choice |
|---|---|---|---|
| Four-day stay | 4 × 0.4GB + 0.4GB reserve | 2GB | 3GB, A$9.95 |
| Fourteen-day stay | 14 × 0.6GB + 1.6GB reserve | 10GB | 10GB, A$17.95 |
The first choice leaves 1GB beyond the calculated total. The fortnight choice matches the budget exactly, including its 1.6GB reserve; don't count the reserve twice. If the daily assumption should be 1GB instead, the fortnight becomes 15.6GB, fitting our 20GB/30-day option at A$24.95 with 4.4GB spare.
To choose your daily input, read per-app mobile use over a known period on your phone. On iPhone, Current Period needs a known reset date; Android lets you select a data-usage period. Include large uploads, app video calls and connected devices in the estimate rather than treating them as free extras.
What the fixed plans cost
| Total allowance | Days once started | Current AUD price |
|---|---|---|
| 1GB | 7 days | A$4.95 |
| 3GB | 30 days | A$9.95 |
| 5GB | 30 days | A$11.95 |
| 10GB | 30 days | A$17.95 |
| 20GB | 30 days | A$24.95 |
The selected 1GB offer has sixty days from purchase to start. The selected 3GB–20GB offers have 180 days. Running validity starts at first supported-network connection; the data is one pool without a daily refill. Same-area data reload is available within running validity, without extending the original expiry.
These Indonesia offers include Bali but don't add Singapore or Malaysia. For an onward country, choose explicitly inclusive regional data or a separate plan; the unused Indonesia balance won't move with you to another country's profile.
Video and sharing can change the choice
Download eligible shows and large files on Wi-Fi before travel, and save useful maps and transfer details offline. That reduces the mobile jobs remaining in the budget. Background photo backups and app updates can still spend data if left on mobile.
Sharing on these set-data plans depends on your phone and the network. The separate seven-day Indonesia unlimited offer costs A$36.95, but its laptop-sharing support is unconfirmed. If you need a work laptop, tell us the exact plan and how much you need to share before buying. If we cannot confirm it will work, arrange suitable Wi-Fi or a plan with confirmed sharing support.
The Bali buying guide compares fixed data, daily high-speed and the unlimited offer, including their different clocks. Don't multiply a daily threshold into a freely shared trip balance.
Save the first address before you set off
Buy within the selected start window and keep the setup email. Install after landing on working airport Wi-Fi after sign-in and a webpage test, or use hotel Wi-Fi if the airport portal isn't cooperating. Select the travel line for data, keep home-line data roaming and automatic switching off, then test mobile data with Wi-Fi briefly off.
Keep the pickup point and villa entrance instructions saved. They're useful while the phone gets connected, regardless of how many gigabytes you buy.
