iOS 27 Introduces New 'iPhone Handoff' Feature
Apple is introducing a new iPhone Handoff feature in iOS 27 that allows users to seamlessly switch between two iPhones while maintaining the exact same phone number on both devices. This new capability simplifies device management by linking a primary hardware device with a companion handset through specialized carrier eSIM provisioning.
For individuals who carry separate devices for work, travel, or personal preferences, managing multiple mobile devices has historically required distinct phone numbers, complex forwarding rules, or constant physical SIM swapping. The upcoming software release aims to resolve this inconvenience directly within system settings.
What Is the iPhone Handoff Feature in iOS 27?
The iPhone Handoff feature is a multi-device cellular management system built into iOS 27. It allows a single cellular subscription and phone number to operate across two individual iPhone handsets at the same time.
This functionality was briefly referenced during Apple's WWDC 2026 keynote event in June. At the event, Apple presented a summary slide that listed hundreds of new features included in iOS 27 and related software platforms, though the company did not elaborate on cellular handoff specifics during the main presentation.
Following months of speculation, additional operational details emerged when MacRumors forum member pdfu shared a video demonstrating the setup procedure. The demonstration illustrated the exact workflow using two simulated iPhones running inside Xcode 27's Device Hub development tool.
How to Set Up and Switch Between Two iPhones with the Same Number
Configuring the feature is handled entirely within standard system menus. Users can initiate and control the pairing directly from the native Settings application on their primary handset.
To access the initial setup, users navigate to the Settings app and open the Cellular menu. From this screen, iOS guides the user through designating device roles for each connected handset.
- Main Device Selection: The user selects their primary iPhone, which serves as the core management host for all cellular account configurations.
- Companion Device Selection: The second iPhone is assigned as the companion device, intended for secondary or active handoff use.
- Main eSIM Allocation: Apple assigns and keeps the user's main eSIM profile active on the designated main iPhone.
- Companion eSIM Provisioning: A paired companion eSIM profile is transferred and installed on the designated companion iPhone.
- Active Switching: Once configured, users can switch operational activity back and forth between both devices while keeping one active phone number.
How iOS 27 Handles Cellular Settings and Location Sharing
Apple has built specific system boundaries into iOS 27 to keep account administrative settings organized when using two devices simultaneously.
All core cellular settings remain strictly managed on the main iPhone. Adjustments to account preferences, plan management, and primary network rules are controlled on the main device rather than spread across both phones.
Location sharing services adapt automatically based on active device status. System location data updates dynamically to reflect whichever iPhone is currently active and utilizing the assigned phone number at any given moment.
Carrier Support and Hardware Requirements
While the feature is built into the core operating system, successfully enabling it requires both hardware compatibility and active carrier activation.
Requirements for iPhone Handoff
- Two compatible iPhone hardware models capable of running iOS 27.
- The official iOS 27 software update installed on both devices.
- Supported carrier network profiles that offer companion eSIM provisioning.
Because the implementation relies on secondary eSIM profile delivery, carrier integration is mandatory. Early reports indicate that T-Mobile in the United States and Deutsche Telekom in Germany are expected to be among the first wireless carriers to offer official carrier support for the feature.
Developer Demonstrations and Expected Release Date
The practical workflow of the iPhone Handoff feature was highlighted through simulated environments in Apple's developer suite. By running dual instances inside Xcode 27's Device Hub, testing demonstrated how paired companion eSIM profiles interact across simulated cellular networks.
Following three months of extensive beta testing across developer and public preview builds, iOS 27 is expected to be released to the general public later this month. Additional details regarding carrier availability and deployment timelines are anticipated alongside the public rollout.
