AT&T is announcing a new network-level advancement called NumberSync capable of sharing one phone number with all connected devices. With NumberSync, AT&T customers will soon be able to use what’s called mobile twinning to share a single phone number with multiple SIM cards in smartphones, smartwatches, tablets, and other connected devices. The goal is to let you send and receive phone calls or messages from all your connected devices without relying on a specific app or operating system feature.
AT&T’s NumberSync feature will soon be able to benefit smartwatches that ship with SIM cards but have their own phone numbers for making phone calls and handling messages. Because NumberSync is a network-level feature, SIM cards on tablets, wearables, and even connected cars will benefit.
NumberSync won’t require smartphones to be on a Wi-Fi network, connected via Bluetooth, or even powered on for other connected devices to work with your real phone number. This also unifies your voicemail inbox to one phone number if you miss or can’t take calls.
As for availability, AT&T says its focused on supporting NumberSync through an ecosystem of devices with the first supported device expected soon and more to follow before the end of the year.
