Apple has unveiled its innovative iPhone Handoff feature, which empowers two iPhones to operate under a singular phone number. Leading the charge in embracing this groundbreaking functionality are T-Mobile in the United States and Deutsche Telekom in Germany. Verizon and EE are also slated to integrate this feature into their services by 2026, with anticipation that additional carriers will follow suit in the coming years. This feature is designed to cater primarily to individuals who utilize both an older and a newer iPhone concurrently, maintain a secondary phone, or manage dual devices for professional and personal purposes. Nevertheless, Apple and the involved carriers have yet to disclose detailed information regarding specific applicable plans, pricing criteria, device compatibility, protocols for synchronizing calls and text messages, or precise timelines for regional launches.
