T-Mobile May Support iOS 27 iPhone Handoff First in US as Launch Nears This Month

Summary
T-Mobile appears positioned to become the first US carrier to enable Apple’s iPhone Handoff, an iOS 27 feature that lets two iPhones share one phone number.
The setup uses a main iPhone’s primary eSIM and a linked companion eSIM on a second device, with users switching the active phone while settings stay managed from the main handset.
Carrier support is essential for the feature to work, and early signs also point to Deutsche Telekom in Germany, though neither carrier has officially confirmed support.
Apple only briefly showed the feature at WWDC 2026; its mechanics surfaced after a MacRumors forum video demonstrated the setup flow on simulated devices.
After about 3 months in beta, iOS 27 is expected to roll out later this month, when launch-day carrier support should become clearer.
