iPhone Handoff could simplify owning both an iPhone Duo and another model
iOS 27 introduced iPhone Handoff, allowing one SIM and phone number to be used on two iPhones simultaneously. The feature could make it easier for people who plan to own both the new iPhone Duo and another flagship iPhone. The article argues this addresses the long-standing hassle of managing two iPhones and separate phone lines.
iOS 27 introduced iPhone Handoff after a June footnote teased it. The feature lets two iPhones share one SIM and number, similar to how a cellular Apple Watch uses an iPhone's line. It may suit buyers considering both the iPhone Duo and another flagship, since the Duo reportedly lacks Face ID and a rear telephoto camera but offers a new form factor.
Previously, two iPhones required separate lines because iCloud does not sync a phone number, adding monthly expense. Handoff detects the active iPhone and moves the eSIM automatically, avoiding manual swaps. Apple's approach mirrors Watch behavior: connectivity shifts when one device is out of range and returns when nearby. Launch limitations exist, but details remain incomplete.
For frequent travelers, remote workers, or professionals carrying separate work and personal devices, sharing one line could reduce monthly costs and simplify device switching. Enthusiasts who buy both the Duo and another flagship may find dual-iPhone ownership more practical. However, carrier support, limitations, and user habits may determine whether the feature changes mainstream behavior or remains a niche convenience.
