Apple's iPhone Handoff Feature Unveiled for iOS 27
Confirmed
In Short: Apple has introduced a new feature called iPhone Handoff for iOS 27, allowing users to designate one iPhone as the main device and another as a companion, sharing a single phone number between them.
The new feature, called iPhone Handoff, is part of iOS 27 and was first spotted in detail by MacRumors after appearing on a brief slide during the WWDC 2026 keynote.
Users can choose one iPhone to be their main device and another as a companion, with the main device keeping the user's primary eSIM.
This practical multi-device feature could be especially useful for individuals who frequently switch between work and personal devices.
The feature, which was only mentioned briefly at WWDC 2026, will allow one phone number to work across two iPhones, providing a seamless experience for users.
