Install your Indonesia eSIM at home, before you fly
- At home, on Wi-Fi
- Within 30 days
- Keep the line off

The short answer
Install the eSIM at home on Wi-Fi, before you fly, within 30 days of buying it. Scan the QR code from your order page, name the line, and keep it switched off until you land. Do not delete the eSIM once added: a QR code can usually be installed only once.

Before you scan
Your phone must support eSIM and be unlocked; dial *#06# and look for an EID, as the phone check sets out. Connect to Wi-Fi: the phone downloads the eSIM from the internet, so do this somewhere with a steady connection, at home if you can. Install within 30 days of buying; if your trip starts later than that, write to the store’s support before installing.
Scan the QR code
Open your order page on another screen, or print the QR code. The store shows the code on screen right after payment and keeps it on that page, so save the link. On an iPhone, go to Settings, Cellular, Add eSIM, and scan. Android: open the SIM settings (Connections, SIM manager on Samsung; Network & internet, SIMs on Pixel) and add the eSIM there. If the camera will not scan, enter the details by hand from the order page.
After it is added
Give the line a name you will recognise, such as Indonesia. Keep it switched off until you land, and do not delete it: a QR code can usually be installed only once. On landing, follow switch it on after landing.
If it fails (Install the eSIM)
When the QR code refuses to scan or the install halts, keep the Wi-Fi on and give it one more try. If it still fails, write to the store’s support with your order page link and your phone model, before you try again.
