Overview
- Apple built iPhone Handoff into iOS 27 so one phone number can be used on two iPhones, with the active device switching when you unlock it.
- T-Mobile has announced a $5 per month charge for the service in the U.S., while Deutsche Telekom will offer it through its MultiSIM product with adding a MultiSIM costing €6.95 per month unless the plan already includes one.
- The feature requires two iPhones running iOS 27, the same Apple ID, FaceTime and iMessage signed in, Messages in iCloud enabled, Wi‑Fi connectivity, and carrier enrollment to work.
- Apple warns some Wallet items and Apple Watch pairings may not transfer between devices, only one iPhone can be active at a time, and disabling the service usually requires contacting the carrier.
- Apple is launching Handoff first with T‑Mobile and Deutsche Telekom and says other operators such as Verizon and EE will add support later this year, which means availability and cost will vary by carrier and market.
