A QR code is
simply a representation of a download link plus activation code for your eSIM
profile. It is easier to scan a QR code than typing a long string of text, but
if for some reason you are unable to scan the QR code, you will have the option
to activate your eSIM by keying in the required information manually. Please
note that QR codes can be used only once. Once a QR code is scanned and an eSIM
profile installed, it cannot be used to install the same eSIM again, whether it
is on the same or another device.
