That's very helpful @DTS Engineer , thank you! Any chance there's a resource/documentation which we can reference on any future updates?

Hi Travis, the app that I work on sells eSIMs to our customers. We have the entitlement which allows us to perform a direct installation via the addPlan method of CoreTelephony. We try to educate and guide our customers through the installation wizard that iOS offers, though we have noticed that the steps in the wizard are different from iOS 18 to iOS 26, e.g. some of our customers report that they are not prompted at all with steps such as labeling the eSIM or choosing what to use for mobile data, etc. What would be the best contact, or is there a source on which we could rely on these changes?
