T-Mobile to Charge $5 a Month for iOS 27 iPhone Handoff

T-Mobile will charge customers $5 per month to use iPhone Handoff, an e-SIM feature that allows the same phone number to be used on two separate iPhones. iPhone Handoff requires carrier support, and at launch, only T-Mobile users in the U.S. and Deutsche Telekom users in Germany will be able to use it. T-Mobile says customers can use their number across two compatible iPhone models and elect which phone is active at any given time. Features like calls, texts, data, mobile hotspot, Scam Shield, and T-Satellite will work on both devices with an eligible plan. Apple is adding support for iPhone Handoff in iOS 27. It requires two iPhones running ‌iOS 27‌ or later that are connected to Wi-Fi and signed into the same Apple Account with FaceTime, iMessage, and Messages in iCloud turned on. It can be turned on when activating a new iPhone or in the Settings app. When iPhone Handoff is enabled, one iPhone serves as a main iPhone and the other iPhone is the secondary device that shares the same number. Moving between the main iPhone and secondary iPhone happens automatically when you unlock one of the devices. A phone number can only be active on one iPhone at a time when using iPhone Handoff. Payment cards in the Wallet app and car keys can work across both iPhones, but Apple warns some Wallet items like transit passes, IDs, or corporate badges might only work on one iPhone at a time. iPhone Handoff also does not transfer an Apple Watch from one iPhone to another. iPhone Handoff works with Dual SIM as long as both eSIMs are from carriers that support iPhone Handoff. Both eSIMs will switch simultaneously when you unlock your iPhone. Each eSIM has to be set up separately. Once set up, iPhone Handoff remains activated until you contact your carrier to turn it off. More information can be found in Apple's support document for the feature. ‌iOS 27‌ is set to launch on Monday, September 14, and the new iPhone 18 Pro models will launch on Friday, September 18.
