GoKawiilApple’s new iPhone Handoff feature, which lets users share a single phone number across two iPhones, will cost $5 per month on T-Mobile. Here are the details.
Deutsche Telekom will also require a subscription
Earlier this year, during the WWDC keynote, Apple quickly showcased a slide containing dozens upon dozens of features and improvements coming to iOS 27, one of which read “Switch between two iPhone devices with the same phone number.”
During yesterday’s “Surprise and Shine” event, Apple’s VP of iPhone Product Marketing, Kaiann Drance, shared more details about the feature:
“iOS 27 improves connectivity with smarter transitions between cellular and Wi-Fi networks and introduces iPhone Handoff that lets you use a single phone number across two iPhones. The number is instantly active on whichever iPhone you pick up. iPhone Handoff launches with T-Mobile and Telekom Germany. Verizon and EE will add support by the end of the year with more carriers to follow.”

9to5Mac consulted Deutsche Telekom’s announcement of the feature, and the carrier does not charge a separate fee for iPhone Handoff specifically.
