T-Mobile today announced Digits, a new service that will let customers use the same phone number across multiple devices, or multiple numbers on a single device. The service makes use of T-Mobile's LTE network and works with virtually all connected devices, including phones, tablets, wearables, and computers. Digits relies on an app. Users can sign in on whichever device is most convenient and immediately have access to their phone number, complete with voicemail, text messages, call history, and other features. The service allows a single handset to support up to five phone numbers without requiring additional SIM cards. Similarly, a single number can be used across up to five separate devices. T-Mobile believes Digits will be particularly appealing to business customers, which will be able to assign a T-Mobile Digits number to workers, regardless of the carrier the employee already uses. Digits can run on phones that connect via AT&T, Sprint, Verizon, et al. Digits works natively with the dialer in Samsung's newer smartphones, including the Galaxy S6, S7, Note 5, and others. T-Mobile customers who have iPhones or other Android phones will be able to use Digits through a mobile app. T-Mobile is allowing a limited number of postpaid customers to test Digits, which is available as a beta. T-Mobile did not say how much the service costs. The company expects to fully launch Digits early next year.
