Apple iPhone Handoff Lets One Number Work on Two Phones
Apple’s iOS 27 introduces iPhone Handoff, a feature that lets users keep the same mobile number active on two iPhones, automatically transferring calls, messages and location data to the device in use.

Apple’s latest iOS 27 update brings a new feature called iPhone Handoff, designed for users who own two iPhones and want to keep a single mobile number active on both devices. The system works by allowing only one phone to be connected to the cellular network at a time, while the other remains offline. When a user unlocks a phone, it becomes the active device and the other phone automatically drops its network connection. All calls, voicemails, SMS, iMessage, RCS, and FaceTime sessions follow the active device, and the Find My location updates accordingly.
How iPhone Handoff Works
To enable Handoff, both iPhones must be signed into the same Apple ID. Users can set it up by navigating to Settings > Cellular > Set Up Cellular or Add eSIM, then selecting the option “Use Number on This iPhone and Another.” This action adds an eSIM for the same number to the second device, eliminating the need to manually transfer the eSIM each time a phone is switched. Once the eSIM is in place, the two phones will automatically sync data through iCloud, keeping contacts, photos, and app data consistent.
Key prerequisites for the feature include iOS 27 or later, a Wi‑Fi connection, a valid Apple ID, and the appropriate settings enabled for Messages, FaceTime, and iMessage. The feature is ideal for people who keep a large iPhone for media consumption and a compact model for everyday use, or for those who simply want to avoid maintaining a second phone number.
Availability in the United Arab Emirates
While the feature is already baked into iOS 27, its availability depends on carrier support. Apple’s UAE website confirms that iPhone Handoff is part of iOS 27, but it does not list UAE operators among the carriers that currently support the service. The feature launched with T‑Mobile in the United States and Deutsche Telekom in Germany. Verizon and EE are expected to add support later this year.
UAE users already enjoy extensive eSIM support, with carriers such as e& and du listed among the more than 500 worldwide carriers that support eSIM. However, eSIM compatibility alone does not guarantee iPhone Handoff functionality; the carrier must specifically enable the feature. Apple advises customers to contact their mobile operator to confirm availability and to inquire about any additional costs. For example, T‑Mobile charges $5 per month for the service, while Deutsche Telekom charges €6.95 on plans that do not already include the required multi‑SIM functionality.
What Happens When You Switch Phones
When a user unlocks the second iPhone, the first phone automatically loses its cellular connection. All ongoing calls, voicemails, and messages are routed to the newly active device. The Find My app updates the location to reflect the active phone, ensuring that location-based services such as “Find My iPhone” or “Share My Location” always point to the correct device. This seamless transition means users never have to manually change settings or transfer data when they switch between phones.
Potential Use Cases and Limitations
iPhone Handoff is particularly useful for:
- Users who own both a flagship and a smaller iPhone and want to switch between them without juggling two numbers.
- Business professionals who need a dedicated device for work and another for personal use, yet prefer a single contact number.
- Travelers who want to keep a local number active while using a secondary device for data and offline use.
Limitations include the requirement for a carrier that supports the feature and the fact that only one phone can be on the network at a time. Users cannot have both phones ringing simultaneously from independent SIMs. Additionally, the feature is not yet available in all regions, and pricing may vary by operator.
Next Steps for UAE Users
UAE iPhone owners can update to iOS 27 and set up Handoff once their carrier confirms support. Until then, the feature remains unavailable, but the underlying eSIM infrastructure is in place. Users should keep an eye on announcements from e& and du, as well as from Apple, for updates on carrier participation and pricing.
In summary, Apple’s iPhone Handoff offers a convenient way to keep a single number active across two devices, but its availability hinges on carrier support. UAE users can look forward to the feature once local operators join the program.
