New apps also make their debut on iOS 26, with the likes of the dedicated Games app and Mac's Preview app coming to the iPhone.

Users may now segregate the conversations they have on the app to only display and share notifications from saved contacts, with others set to be separated into a different folder called Unknown Senders. Spam messages will likewise be sent to a different folder.

Users may also take advantage of an easier way to transfer eSIM from a previous device to their new iPhones powered by iOS 26. Apart from this, there is also the capability to cross-transfer an eSIM from Android devices to iPhones via the latest operating system.
