What is Installation QR code?

Some phones will read it and offer a shortcut to the installation screen, but the route to rely on is the add-a-line section of Settings, scanning from there, because that is the path the system was designed for. If the camera app reads it and nothing happens, the code is not broken; try again through Settings.

Usually not, because the activation code is generally marked as used at the first download. Whether you can get the profile back depends on the provider's policy on reissuing, and some attach conditions or a fee. Before deleting any profile, ask first rather than deleting and asking afterwards.

Only if that handset can read a QR code from an image in its photo library, which depends on the manufacturer and the OS version. If it cannot, an image stored on the same phone is unusable. The dependable approach is to have a second device ready, or to use manual entry instead.

Check the spam folder and any promotions tab first, since automated mail often lands there, then confirm the email address you entered at checkout was spelled correctly. If it is still missing, message us on LINE at https://lin.ee/skDPoNx or email esimonline.asia@gmail.com with your order number and the address you used.

Moving a profile is not the unplug-and-replug of a plastic card; it goes through the provider's process, and some do not support transfers at all. Settle on the phone you will actually travel with before scanning, because once a profile is on a handset, changing your mind is usually more trouble than expected.

They are the same thing in two forms. The QR code is an image containing text; the activation code is part of the text inside that image. Providers usually supply both so you can pick whichever suits, and scanning or typing produces the same profile.
