Try the supported install button first
Open your private eSIM page on the phone you want to use. If an installation button is available and supported by that device, follow it into the phone’s system setup. Device and software support can vary.
Some phones allow an eSIM QR code to be selected from saved photos. Use that option only if your phone’s eSIM setup screen offers it.
Otherwise, choose manual installation and copy the exact SM-DP+ address and activation code from your private eSIM page. Enter each value in its matching field without extra spaces.
If none of those options is available, show the QR code on another phone, tablet or computer and scan it from the phone being set up. Never post the QR code publicly or send it to someone who is not helping with your installation.
