Use your number across devices with DIGITS.

Enjoy the flexibility and convenience to use your phone number on any compatible internet-connected smartwatch, tablet, or computer. Have multiple numbers? Access up to five lines from a single device.
What you can do with DIGITS:

Use your number from anywhere.

DIGITS works on any compatible internet-connected device you have with you. So if you forget your phone at the office, you can use your tablet or computer to text and make calls.

Set up separate numbers for different groups.

Easily add numbers for teams, clients, or even your family—and use them all from one device. No more carrying around multiple phones.

Share one number with multiple people.

Keep employees connected with a single number that rings on every phone so you never miss a call.

Have two phones that use one number.

Leave your high-end work phone at the office and take a separate phone out into the field. Your calls and texts will go to both devices.

Control when and how people reach you.

See how DIGITS can help simplify how you receive and make calls, send and receive texts, and more from your work and personal devices.

Got questions?

How much does DIGITS cost? What if I need an additional number?

All your existing T-Mobile numbers are now DIGITS lines. You can use them for free on any compatible internet-connected device via the DIGITS app or on phones with the DIGITS functionality built in.

If you want additional DIGITS lines, you can purchase a DIGITS Talk & Text line for $10/month (with AutoPay).

If you want your smartwatch to use the same number as your primary phone, you can purchase Data with Paired DIGITS for your smartwatch for just $10/month (with AutoPay).

Do I need a new phone to use DIGITS?

No. All you need is a compatible device and the DIGITS app. The DIGITS app will run on:

  • Any Android device running Lollipop (5.0+) or above. Download the DIGITS app from the Play Store.
  • Any iOS device running iOS 9 or above. Download the DIGITS app from the Apple App Store.
  • Any PC or Mac using Chrome or Firefox. Visit https://webdigits.t-mobile.com to log in or download the application.

Can I use my DIGITS number on a non-T-Mobile device?

Yes. Even if your Android or iOS device is with another carrier, you can make and take calls or send and receive texts using the T-Mobile DIGITS app. Once you’ve downloaded and logged into the app, you can turn on your DIGITS. If the device is not on the T-Mobile network, any data used will decrement from the phone plan with the other carrier.

How do I access and manage my DIGITS?

If you have a T-Mobile number, you can use the T-Mobile DIGITS app on any Android (5.0 +) or iOS (iOS 9 +) device, even if the device is with another carrier. You can also access DIGITS from any Mac or PC browser by visiting https://webdigits.t-mobile.com on Chrome or Firefox, or download a standalone app. The US versions of the Samsung Galaxy S6 or newer and the LG 5 or newer already have the DIGITS functionality built in, so you don’t need to download the DIGITS app. For additional support, visit http://www.t-mobile.com/DIGITS.

Which Samsung and LG smartphones have the DIGITS functionality built in? And what do I do if I don’t have one of those devices?

There are multiple Samsung smartphones that have the DIGITS functionality built in. They are: Samsung Galaxy S9, Galaxy S9+, Galaxy S8 Active, Galaxy S8, Galaxy S8+, Galaxy S7, Galaxy S7 edge, Galaxy S6, Galaxy S6 edge, Galaxy S6 edge +, Galaxy Note9, Galaxy Note8, Galaxy Note5, Galaxy J7 Prime, Galaxy J7 Star, and Galaxy J3 Prime.

The following LG smartphones have DIGITS functionality built in:  LG G7, G6, G5, Stylo4, V30+, V30, V20, and Q7+.

Make sure that the device has been updated to the latest software version. If you have any other Android or iOS device, simply download the DIGITS app from the appropriate app store. 

How do I get DIGITS set up?

First, you need to unlock the DIGITS function. Open the T-Mobile app and select Usage & Plans. Find the line you want to unlock and select View Line Details. Then, select “unlock” on the DIGITS card. Restart your device, then you can search your settings for “Multi-line settings” and log in with your T-Mobile ID. Once logged in, you will see a list of all lines available to you, which you can turn on and off as needed. For additional support, visit http://www.t-mobile.com/DIGITS.

How do I share my phone number with other devices, like my desktop, laptop, or tablet?

Simply download the DIGITS app on the device you’d like to share your number with. On PC and Mac, go to https://webdigits.t-mobile.com to log in or download the application. Then, open the app, log in with your T-Mobile ID, and turn on your line.

My mobile phone number already works on all my Apple devices (iPhone, iPad, Mac). How is this different?

Continuity is restricted to the iOS ecosystem. DIGITS allows calls and texts to work on any device in which you have enabled your DIGITS lines, regardless of the operating system. If you use Apple devices exclusively, then there’s no need to use the DIGITS app.

Can I call or text 911 with DIGITS?

Yes. But calls and texts to 911 still work best from your landline or primary cell phone number, and without using Wi-Fi. You should always provide your actual location and callback number to the 911 operator, and be aware that if the operator calls you back, the call may be answered by others sharing your DIGITS line. See the DIGITS Terms of Use for additional 911 information.

How have you made sure DIGITS is secure?

DIGITS calls and texts use the same leading level of security and encryption as traditional T-Mobile calls and texts.

I want to use my main phone number but switch between phones such as an iPhone and Android device without swapping my SIM. Can I do this?

Absolutely. There are two ways to do this depending on your needs.

If both devices already have their own phone number and data plan then you can access your primary number from either phone any time through the DIGITS app. Manage all your DIGITS here: https://mydigits.t-mobile.com.

If you want each phone to simply share the same primary number and you don’t need high-speed data on the second device then you can pair your number with another device for just $10 a month using a Data with Paired DIGITS plan.

*Data with Paired DIGITS comes with unlimited data at 600 Kbps.
