What should I prepare before installing an eSIM?

Confirm that your device supports the purchased eSIM and can use the relevant network. Check coverage, when validity starts and any installation deadline before deciding whether to install before travel. Installation normally involves downloading a profile, so prepare a stable internet connection and sufficient battery. Find the correct credentials in your order details or delivery email and keep credentials for different orders and devices separate. For QR installation, display the code on another trusted device or use an image-reading method supported by your phone manufacturer. If manual installation details are supplied, retain all fields exactly as provided. Do not remove another line that you still need. If you see an already-used code, invalid credential or download error, record the message and contact support before repeatedly deleting profiles, reinstalling or trying the same credentials on several devices.
