T-Mobile’s Digits looks to expand your phone number to all of your devices

T-Mobile is no stranger to shaking up the mobile world, having previously unveiled unlimited video streaming, streamlined data plans and hassle-free device upgrades. Now it has a new Un-carrier trick up its sleeve: a single number for all your devices and multiple numbers on a single device.

Called Digits, the program lets you share your T-Mobile number with any Internet-connected device, including smartwatches, computers, and tablets. As the company explains in its press release, “Just log in and, bam, your call history, messages, and even voicemail are all there. And it’s always your same number, so when you call or text from another device, it shows up as you.”

The impact on you at home: You don’t have to be a high-powered CEO or a tech journalist to want your number to work on different devices. We might not be making as many calls as we once did, but we use our phones to communicate on the go more than ever, and Digits is certainly an interesting idea. It remains to be seen how well it will work in practice, but on paper, it seems as though T-Mobile has developed a system that could truly upend the carrier method.

More numbers, less problems

This isn’t a Bluetooth method like iOS’ Continuity, nor does it necessarily require the device to have a SIM card or cellular chip. With Digits, T-Mobile’s engineers built “an entirely new IMS (IP Multimedia Subsystem) service management layer and Identity Management solution” that is device agnostic, all but eliminating the need to swap out SIMs to change phones.

Just log in and, bam, your call history, messages and even voicemail are all there.
Also part of the Digits program is the ability to use multiple numbers on the same phone without needing a mess around with a dual-SIM device. T-Mobile claims you can “seamlessly switch back and forth between your numbers” and specifically touts the plan as a boon for businesses: “You’ll be able to share Digits among employees, so your entire sales team can get both calls and texts to your company’s sales line—no more missed sales calls. And if an employee leaves, the business will be able to keep the employee’s Digits number along with any business contacts and relationships.”
