Yes, it is possible to move data from an Android device to an iPhone after the initial setup of the iPhone. However, the methods available for doing so will depend on the type of data you wish to transfer and the specific devices involved. For example, you can use apps such as Google Drive or Dropbox to transfer photos and videos, while contacts and calendar events can be transferred using a service such as Google Contacts or iCloud. Additionally, you can use third-party apps such as Move to iOS to transfer data wirelessly, or connect the devices to a computer and use PC software such as iTunes to transfer the data.
