T-Mobile's New 'Digits' Service Lets Customers Use Multiple Numbers Across All Their Devices

T-Mobile is famous for uncoupling device costs from mobile service plans through its "Uncarrier" initiatives, a move that changed the entire smartphone industry, and now the company is aiming to do the same thing with phone numbers.

T-Mobile's newly announced "Digits" service lets customers use their phone number across multiple devices, including smartphones, tablets, wearables, and PCs, while also allowing multiple phone numbers to be used on a single device.

Many people have separate phone numbers for work and personal use, and the Digits service, which is a souped-up blend of AT&T's NumberSync and Google Voice, puts both numbers on one smartphone. And then those numbers can be used on any device a customer owns, even if it's not on the T-Mobile network.

"Simply put, DIGITS is breakthrough technology that won't be replicated any time soon," said Mike Sievert, Chief Operating Officer of T-Mobile. "This isn't the first time you can add extra numbers to a device, but this IS the first time you can do it all -- multiple numbers on one device and one number on multiple devices - and do it with carrier-grade quality. DIGITS is your real T-Mobile number with every bit of the reliability, call prioritization, services and mobility you expect."

While Digits is built directly into newer Samsung smartphones like the Note 5 and Galaxy S6 and later (purchased on the T-Mobile network), on iOS devices, Digits will be available through an iOS app. On the Mac, Digits will work through the browser.

When Digits is used on a device without cellular service, voice calls and texts will be received over a Wi-Fi connection, delivering "crystal clear HD voice quality."

Simple Choice and T-Mobile ONE customers can sign up to test a beta version of the Digits service. iOS 9 and newer, Android 5.0 and newer, and Firefox or Google Chrome are required.

During the beta testing phase, Digits is free, but it will require customers to pay an additional fee when it launches next year. Pricing has not yet been announced.

This is why I love T-Mobile. The subtitles are amazing... at 6:16, "It's advanced AF" ... and at 11:55 the phone representing "Discount Carriers" with the Sprint logo under it, next to phones for AT&T and Verizon.

I'm sure there are variations on this product around, but if it works as advertised (and I'm curious to see just how they integrate that), it'll have major advantages over so many other services. Specifically that i'll work with messaging, single voicemail stores, etc, AND incorporate use over traditional phone networks.

Yeah, T-Mo may not work everywhere, but they work enough of the major places, and tech like this covers the last mile beautifully.

I'm assuming this will work about as well as TMO Wi-Fi Calling. Which is to say, terrible. I finally had to turn it off — despite having a solid 60/5 mbps connection with <20 ms latency — because during every other call, people would say "I can't hear you" or "You sound like you just stepped into a cave". This even happened on Wi-Fi connections at friends' houses with different providers, so it's something on TMO's end. I never have this issue with LTE.
Charter? They have 60/5 and 100/7. And their routing is terrible and broken. The jitter alone kills voip. This isn't T-Mobile's fault, it's your ISP's fault.
