This could come in handy.
Following the release of iOS 9.1 on Wednesday, Sprint announced that iPhone users updating their firmware will be able to take advantage of improved Wi-Fi Calling, expanding on Apple’s Continuity feature.
These calls can now be set to ring on any Apple device signed into the iCloud with the same Apple ID.
The core iPhone must be an iPhone 5s/5c or later, and all devices must be updated to the latest version of iOS, OS X, or watchOS. After that, each secondary device should have “Calls from iPhone” toggled on under FaceTime settings.
While Continuity provides similar functions, it normally requires an iPhone to have both cellular and Wi-Fi connections active. With Wi-Fi Calling, the feature should work even when a cellular signal is weak or non-existent.
Wireless carrier AT&T recently announced NumberSync, which performs much like Continuity, although it casts a wider net and links devices through LTE/isn’t specific to Apple’s platform. The current limitation is that these devices have to be on a Mobile Share plan.
Stay tuned for additional details as they become available.
