Apple's iOS 27 includes a feature allowing users to switch a single phone number between two different iPhones, a capability previously unaddressed during the WWDC keynote.
The feature is described as potentially functioning similarly to how cellular Apple Watches share a number with an iPhone, though Apple has not confirmed the specific technical implementation.
Reports indicate that the functionality may require carrier support to operate, with the feature expected to be available following the general release of iOS 27 in September.
