👍 Apple is making life easier for those who use two iPhones with a new feature in iOS 27
🤝 A new “iPhone Handoff” feature is coming to allow users to have two iPhones running the same number, working as main and companion devices
📱 It looks like both T-Mobile and Deutsche Telekom are set to be the first carriers to support the feature
📅 “iPhone Handoff” was first mentioned at WWDC 2026, although Apple gave no specifics as to what to expect from it
Apple has looked to fix the pain of using two iPhones with a new feature built into iOS 27.
As per MacRumors, Apple has added a new “iPhone Handoff” feature with the upcoming version of iOS that will allow you to switch between two iPhones while using the same phone number.
The functionality was mentioned briefly at WWDC 2026 back in June on a slide where Apple listed hundreds of new features coming to iOS 27, but stopped short of any specifics.
A MacRumors forum member has shared a video that shows how the feature will work, using two simulated iPhones running in Xcode 27’s Device Hub.
The “iPhone Handoff” feature can be set up from the Settings app under the Cellular menu. During the setup process, you can choose which iPhone you want to be the main device – i.e the one you use most often – and which one you want to be the companion device.
Apple says a user’s main eSIM will remain on the main iPhone, while the companion iPhone will receive a companion eSIM, and this will enable you to switch between the devices back and forth while using the same phone number.
All cellular settings are managed on the main iPhone, and location sharing is based on whichever iPhone is actively using the phone number.
As well as needing two iPhones running iOS 27, the Handoff feature is seemingly going to require carrier support. The MacRumors forum post notes that T-Mobile in the USA and Deutsche Telekom in Germany may be the first to support this feature.
