An activation code — sometimes called AC_Token in GSMA specifications — is a short string embedded in your QR code that unlocks *your* profile on the SM-DP+ server. Format: 1$smdp.example.com$XXXX-XXXX-XXXX-XXXX.
Single-use, on purpose
The GSMA specification requires the SM-DP+ to invalidate an activation code the moment a device successfully downloads a profile with it. This prevents the same profile from being installed on multiple devices — an eSIM is device-bound by design.
If you accidentally scan the QR on the wrong phone, sign in at openline.com and hit Reinstall eSIM to get a fresh code. The old one is dead the moment it's consumed.
