What should you check in an Indonesia eSIM?
- Plan size for your trip: Work out how much data you'll use, then pick the plan to match. For a week of standard use (about 4.9 GB in all), 5 GB for 30 days suits it. For heavy use (about 12.6 GB in all), take 20 GB for 30 days. Not sure? Read how much data you need.
- Speed after a daily allowance: eSIMology's daily allowances go up to 10 GB a day. Once you use up the day's allowance, speed drops to 1 Mbps. The speed is printed on every plan, so you know it before you pay. Heavy users should look at the daily allowances or a bigger fixed plan, such as 50 GB for 30 days.
- Where your data goes: On eSIMology's plans, data reaches the internet through Singapore.
- Top-ups and data left: Most eSIMology plans can be topped up, so you can add data without buying a new eSIM. Check what's left on a web page, with no app to install.
Fixed GB or daily data: which Indonesia eSIM fits your trip?
- A week in Bali with Grab and WhatsApp, light use: Light use over seven days comes to about 1.8 GB in all, so eSIMology's 2 GB for 15 days fits. You pay for the data once, and there's no daily count to track.
- Three days in Jakarta and Yogyakarta, using Gojek, light use: That comes to about 0.8 GB in all, so eSIMology's 1 GB for 7 days covers it.
- Two weeks across Lombok and Labuan Bajo, heavy use: Heavy use over 14 days comes to about 25.2 GB in all, which matches eSIMology's 50 GB for 30 days. Most plans can be topped up if you run short. If you'd rather pay by the day, eSIMology's daily allowances go up to 10 GB a day.
- Comparing other companies: Holafly sells unlimited plans by the day, in 3, 5, 7, 10, 15 or 30 days. Airalo sells fixed-GB and unlimited plans by the day, with the same day options. Saily sells both too, with unlimited options from 1 to 30 days, plus 90 and 365.
