iOS 27 to introduce iPhone Handoff, allowing two phones to share one number

When iOS 27 lands later this month, it will bring a feature called iPhone Handoff that enables users to pair two iPhones, designating one as the primary device and the other as a companion, with both sharing the same number. A demo clip running in Xcode 27’s Device Hub illustrates the setup process, as reported by The Verge.

The timing aligns with the expected launch of Apple’s foldable iPhone Ultra, which has been described as both chunky and extremely expensive. The Handoff feature could address practical concerns: users may not always want to carry the larger, pricier foldable device on every outing, instead switching to a more compact iPhone while keeping the same number active. Apple had briefly mentioned the feature during its WWDC keynote in June but offered no details at the time. The new demo provides the first clear look at how iPhone Handoff will work, though the company has not yet released the final version of iOS 27 to the public.

Why This Matters

For users who own multiple iPhones, the Handoff feature eliminates the need to swap SIMs or manage separate lines, offering seamless continuity.
The feature is strategically timed ahead of the foldable iPhone Ultra, potentially making the large device more practical for everyday use when users can leave it behind and still stay connected.
It reflects Apple’s broader push toward deeper device integration within its ecosystem, a key differentiator from competitors.

Background

Apple has long offered Handoff features across Mac, iPad, and iPhone for tasks like calls and messages, but this is the first time the company has extended the concept to allow two iPhones to functionally share one phone number. The iOS 27 update was first announced at Apple’s Worldwide Developers Conference in June, and the foldable iPhone Ultra is widely expected to be unveiled at a separate event later this month. Apple has not disclosed pricing or exact dimensions, but early reports suggest the device will be notably larger and more expensive than current iPhone models.

Key Perspectives

Apple users: The feature promises greater flexibility, especially for those who might adopt the foldable as a secondary device but still rely on a standard iPhone for compact daily carry. Carriers and network operators: Seamless number sharing could reduce complexity for subscribers, but may require backend support for dual-device provisioning. Critics: Some may question the necessity of the feature, arguing that existing solutions like forwarding or virtual numbers already cover similar use cases. Privacy and security concerns could also arise if the companion device is lost or compromised.
