The short answer
Install the eSIM at home on Wi-Fi before you fly. After landing, switch it on and choose it for mobile data; if it does not connect, turn on data roaming for that line. If it does not work and cannot be fixed, you get a full refund. The plans here run on Telkomsel in Indonesia.

Coverage in Indonesia: what to expect
Indonesia has three mobile networks: Telkomsel, XL Axiata and Indosat. Indosat Ooredoo Hutchison was formed in 2022, when Indosat and Hutchison 3 Indonesia merged. Each network publishes its own coverage map, so check the map for the places you are going. An eSIM for Indonesia runs on an Indonesian network, and that network's name appears next to the eSIM line once it connects.
Registration: the passport step for Indonesian SIMs
A SIM card bought in person in Indonesia is registered to the buyer's passport at the counter, and Indonesia pairs that registration with device registration for phones bought abroad. This eSIM is bought online and delivered as a QR code, and nothing on this site asks you for a passport in advance. If a plan carries a registration step, it is stated on the plan before you pay.
Troubleshooting
The QR code will not scan
Check the Wi-Fi first, then scan again from another screen, or key in the details by hand from the order page. On certain phones, the eSIM gets added through the settings rather than the camera.
The eSIM is installed, but no signal shows
Start with the line's own switch: it has to be on. Then put airplane mode on and off, and let the phone take a couple of minutes to find the network.
There is signal, but no data
Make the eSIM line the one carrying mobile data. If data still will not start, switch data roaming on for that line; that move is the store's fix for a line that does not start.
Data works, then stops
Your order page holds the answer: when the days or the data in the plan run out, mobile data can slow or stop until the plan ends.
The home SIM keeps carrying the mobile data
Aim mobile data at the eSIM line and turn off the switch that lets mobile data move between lines, so the phone can never fall back to your home line.
I deleted the eSIM by mistake
Include your order page link and write to the store's support before trying anything else: a QR code's install usually happens once.
Every check is done and still no connection
Write to the store's support with your order page link and your phone model while you are still in Indonesia. If it cannot be made to work, you get a full refund.
Refunds: what can be refunded
When an eSIM does not work and no fix helps, the store refunds it in full. One that works but is no longer wanted is not refunded, and neither is one the phone cannot install.
If the eSIM does not work and we cannot fix it, you get a full refund.

Quick answers
What does a plan name before I pay?
Its Indonesian network, Telkomsel; the data and the days; that it is data only; and its price in US dollars with tax.
Does the eSIM have a phone number?
No, the plans here carry data only. Your own number stays on in your home SIM.
Should data roaming be on?
Only when the eSIM line will not connect does it need to go on, and only on that line: the store gives that as the fix for a line that does not start. Your home line keeps it off.
When should I install it?
On Wi-Fi, at home, inside 30 days of buying, with the line kept off until you land.
Can I use WhatsApp on my own number?
Yes. Your own number keeps working in WhatsApp, over the eSIM's data.
Who answers if something goes wrong?
Whoever took the payment: write to that store's support and include your order page link.
