Hello,
If you use Telerik Platform to develop and build the app, you can debug it while running it on device. You can use the classic Windows client, the command-line interface and the extension for Visual Studio to debug the app white it is running on a connected device.
Alternatively, you can debug your app remotely. For more information about remote debugging, see Debugging iOS PhoneGap Apps with Safari's Web Inspector.
If none of the above approaches display any errors, you would need to get the iPhone device logs to examine whether there are any errors logged in them. Those are the only options I can think of for pinpointing the cause for the issue.
As for the Device Simulator, if you're referring to the Telerik Platform Device Simulator, then I must note that although closely mimicking the look and feel of the app, it cannot really replicate the app behavior on a device. For instance the Device Simulator won't be able to simulate the behavior of custom plugins so if the issue is related to a plugin API, you will only see it while the app is running on a device or in a native emulator.
