Verizon said it would charge $10 a month for Handoff, which switches the active device for one phone number between two compatible iPhones running iOS 27. It activates one device rather than operating two lines simultaneously, and the announcement gave no specific launch date. The price exceeds T-Mobile’s $5 monthly charge, but pricing and support for the feature differ by carrier. These are US service terms, not an indication of availability or pricing in South Korea.
