One mobile number, two phones: What is iPhone handoff and which carriers support it?

Apple's Handoff feature is designed for users who frequently switch between multiple iPhones, allowing for a seamless transition of tasks and connectivity between devices. This functionality is particularly useful for those managing separate phones for professional and personal use. The system ensures that activities, such as browsing, messaging, or app usage, can be picked up exactly where they were left off on a secondary device. Beyond simple task continuity, the feature relies on specific carrier support to synchronize mobile numbers and cellular services across hardware. As users look to streamline their digital workflows, understanding the technical requirements and carrier compatibility for Handoff becomes essential. This guide explores how the feature operates, the benefits of maintaining a unified digital identity across two devices, and how to verify if your current mobile provider supports this integration to ensure a smooth transition between your primary and secondary iPhones.
