Apple recently unveiled a feature called iPhone Handoff, which allows a user’s cellular phone number to seamlessly switch between two iPhones. The number automatically becomes active on whichever device you pick up. However, AT&T has made it clear it won’t be supporting iPhone Handoff—at least not in the near term.
What is iPhone Handoff?
iPhone Handoff is a new function that lets users share a single phone number between two iPhones. When a number is set up for Handoff, it instantly routes incoming calls and texts to whichever device you are actively using. It’s far more streamlined than manually enabling, disabling, or moving an eSIM between devices, which has been the typical workaround.
AT&T’s stance vs. other carriers
At the moment, AT&T has made no announcement that it will support iPhone Handoff. A company spokesperson emphasized that AT&T is currently focused on other innovations, such as eSIM activation and transfer tools, rather than adopting this new Handoff capability.
T-Mobile is the only U.S. carrier currently supporting iPhone Handoff, though it charges $5 per month for the feature. Apple has confirmed that Verizon plans to add support by the end of this year, and that more carriers will follow. Outside the U.S., Germany’s Telekom is already a launch partner, with EE also set to adopt it by year’s end.
The reluctance from AT&T may stem from a misunderstanding of how Handoff differs from standard eSIM tools. In contrast to manually managing an eSIM from device to device, the Handoff feature automatically switches the number between phones with no manual steps. Early users testing iPhone 18 Pro devices report that the switch feels instantaneous.
For AT&T customers, this means missing out on one of Apple’s key innovations in iOS 27.2 unless the carrier changes course. The decision highlights differing priorities among mobile providers when it comes to value-added features versus infrastructure or billing adjustments.
What this means going forward: If AT&T doesn’t reverse its position, customers who want iPhone Handoff will need either to use a supporting carrier or wait until AT&T decides the feature aligns with its product roadmap and business model. Tech watchers should pay close attention to AT&T’s announcements in the coming weeks, especially as Apple says Verizon and others are coming onboard by year’s end.
