The camera will not read it
Usually a screen problem rather than a code problem: raise your screen brightness, avoid glare, and try again. If you are trying to scan a code displayed on the same phone you are installing onto, that cannot work — use manual entry with the SM-DP+ address and activation code from your order.
“This code is no longer valid”
Profile download links have a limited lifetime on the supplier’s server. If yours has lapsed and the plan has not been installed anywhere, contact us with your order number — a fresh profile can usually be issued.
“This code has already been used”
A profile can normally only be downloaded once. If you installed it and then deleted the line, or installed it on a different device, the code is spent. Do not buy a replacement plan before talking to us: message us first and we will check the actual state of the eSIM with the supplier.
