iPhone Handoff will seamlessly share one number between two phones

iPhone Handoff 功能将实现两个手机共享同一个号码

When iOS 27 lands later this month, it will have a feature called iPhone Handoff that lets you switch between two phones using the same number. It was briefly mentioned during the WWDC keynote back in June, but there were no details at the time. Now there’s a demo clip showing how to set up the feature running in Xcode 27’s Device Hub. It lets you pair two iPhones, using one as your main device and the other as its “companion.”

当 iOS 27 在本月晚些时候发布时，它将包含一项名为“iPhone Handoff”的功能，允许你在两部手机之间切换并使用同一个号码。该功能曾在六月的 WWDC 主题演讲中被简要提及，但当时并未透露细节。现在，一段演示视频展示了如何在 Xcode 27 的设备中心（Device Hub）中设置该功能。它允许你配对两部 iPhone，将其中一部作为主设备，另一部作为“伴侣设备”。

Launching the feature now makes sense with the expected launch of the foldable iPhone Ultra right around the corner. People might not always want to take a chunky and extremely expensive device out with them. So Handoff would let users temporarily switch over to a cheaper, smaller device — like that cracked iPhone 13 you’ve been stubbornly refusing to upgrade.

考虑到折叠屏 iPhone Ultra 即将发布，现在推出这项功能合情合理。人们可能并不总是想随身携带笨重且极其昂贵的设备。因此，Handoff 功能可以让用户暂时切换到更便宜、更小巧的设备上——比如你那台一直固执地不愿升级、屏幕已经碎裂的 iPhone 13。

The feature will require carrier support, however. References to T-Mobile US and Telekom.de were found in the code, but support beyond that is unknown.

不过，该功能需要运营商的支持。代码中发现了对 T-Mobile US 和 Telekom.de 的引用，但除此之外的其他运营商支持情况尚不明确。
