In certain circumstances, incoming calls may display the caller ID as 774-828-368-6237 or 865-6696 rather than the expected "No Caller ID". These calls originate from a customer that has their caller ID permanently blocked or has used the *67 code to block caller ID on a specific call.
Some users may not see the "Phone is Activated" pop-up message after walking through the Out-of-Box-Experience/set-up. The activation may happen prior to set-up being completed and the "Phone is Activated" message can pop up behind the set-up screens.
To verify activation, users can look for the LTE indicator in the upper right-hand corner of the screen, pull down the control panel and look for Sprint in the upper left, or users can simply attempt a phone call to confirm activation.
Sprint and Apple are aware of this issue and working to resolve.
