Apple's New Dual-Phone Feature Costs Five Dollars a Month
Apple is rolling out a feature that allows one number to work on two devices, but it comes with a monthly fee and strict usage limits.
Apple is introducing a new capability in iOS 27 that allows a single phone number to be used across two iPhones. The feature, known as iPhone Handoff, launches alongside the new iPhone 18 series and is initially available on T-Mobile in the United States and Telekom in Germany. While the concept of sharing a number between devices sounds convenient, it is not free.
T-Mobile has confirmed that the service will cost $5 per month. This charge applies to any iPhone running iOS 27, including the newly launched models. The cost reflects the carrier infrastructure required to support the dual-device setup, turning a standard single-line subscription into a shared service.
One number active on one device only
The primary limitation of iPhone Handoff is that the number can only be active on one phone at a time. If you switch the active status to the second device, the first one loses its connection to that specific line. This means you cannot receive calls or texts on both phones simultaneously with the same number.
For users who need true simultaneous access, this solution may feel restrictive. It is designed for occasional switching rather than constant dual-use, which is a significant trade-off compared to owning two separate lines.
Availability and setup requirements
The feature is accessible through the Settings menu on any iPhone that has updated to iOS 27. Since the new iPhone 18 Pro, Pro Max, and Duo models ship with this software pre-installed, they support the feature immediately upon purchase. Older devices will need to complete the software update to enable the functionality.
GSMArena notes that while the technical setup is straightforward, the carrier support is currently limited to specific networks. Users on other providers should wait for further announcements before expecting access to this dual-device option.
The cost of convenience
At $5 per month, the fee is modest, but it adds up over time. For many users, the cost may exceed the actual value if they rarely switch between devices. It is a niche feature for those who need flexibility without the full expense of a second line.
Ultimately, the decision to adopt iPhone Handoff depends on how frequently you need to move a number between two physical devices. If that is a rare occurrence, the monthly fee might not justify the convenience.
