That is very helpful, thank you @DTS Engineer ! Any chance that these are documented somewhere so that we may reference them on any future changes?

Hi Travis, I work on an app that sells eSIMs and uses the CoreTelephony addPlan entitlement for direct installation. We guide users through the iOS installation wizard, but have noticed differences between iOS 18 and iOS 26. Some users are no longer prompted to label the eSIM or choose mobile data settings. What is the best contact or documentation to track or rely on these changes?
