Two iPhones, One Number: iPhone Handoff Explained
iPhone Handoff is a new iOS 27 feature that lets two iPhones share the same phone number for calls, texts and cross-device app use; setup requires both devices on iOS 27+, on the same Wi‑Fi and signed into the same Apple ID, with one phone designated as the primary and both devices able to use eSIMs; as of the article, only T-Mobile (US) and Telekom (Germany) have confirmed support, with T-Mobile charging an extra $5/month; limitations include no Apple Watch handoff between devices, some wallet items may not work, and you must transfer the eSIM when replacing a device; disabling requires contacting the carrier.
