Continuity was introduced to the iPod touch, iPhone, iPad and Mac with the release of iOS 8 and OS X Yosemite. The feature allows iOS and Mac users to easily share data between devices, such as starting a document, email, or message on one device and finishing on another. The iPhone Cellular Calls feature allows users to make and receive calls from their iPad, iPod touch, or Mac when their iPhone is on the same Wi-Fi network. You can disable this feature by navigating to Settings > FaceTime then tap "iPhone Cellular Calls" slider so it is OFF / WHITE.
