The T-Life app (formerly known as My T-Mobile) is your digital control panel for everything T-Mobile. It puts everything you need in one place, letting you handle your entire account without calls or store visits. You can manage your plan, shop for devices, pay your bill, add lines, and control connected services like home internet—all in just a few taps.

App Store

Google Play Store

Not only does the T-Life app help keep your T-Mobile services organized, but it also delivers exclusive benefits through T-Mobile Tuesdays.

Read on for step-by-step instructions on how to install, use, and troubleshoot the T-Life app.

What you need to use the T-Mobile app

Before you dive in, ensure you meet the basic requirements:

A T-Mobile account (unless you want to switch to T-Mobile via the app).
For Android users: A T-Mobile compatible phone with Android 11 or newer.
For iPhone users: A T-Mobile compatible phone with iOS 16 or newer.
If your device doesn’t meet these requirements, you can always manage your account online via T-Mobile.com.

Switch to T-Mobile with the T-Life app

Not a T-Mobile customer yet? Switching is fast and easy, especially for Verizon and AT&T users. You can complete the entire process in about 15 minutes using the T-Life app:

Download the T-Life app.
Open it and tap the switching banner.
Select Easy Switch and choose your current carrier.
Upload a recent bill. The AI then recommends the best T-Mobile plan for your budget and automatically ports your number.

T-Mobile offers plans for seniors, families, and anyone looking for an affordable prepaid option. No matter which you choose, you'll get access to the largest and fastest 5G network in the country.

Logging into the T-Life app is straightforward, but the steps will differ depending on whether you're a first-time user setting up your T-Mobile ID, a returning user with saved credentials, or someone using biometric authentication like Face ID or fingerprint recognition.

Follow the steps that match your situation below:

First time logging in with a T-Mobile ID

If you don't have a T-Mobile ID, you can easily use the T-Life app to help get one. Just follow these steps:

Open the T-Life app and tap Manage in the bottom bar.
Tap Log in.

You can get your T-Mobile ID through the T-Life app when you sign in for the first time.

Open the T-Life app.
Under Manage, enter your username and password.
Select Log in.

Skip the password hassle by enabling biometric login:

Open the T-Life app and tap Manage in the bottom bar.
Enter your T-Mobile ID and password.
Toggle Face ID or Use Fingerprint on (you can find it below the password input box).

Logging in while traveling internationally?

If you're on vacation abroad and want to check your T-Mobile bill while away, make sure you're connected to Wi-Fi before attempting to log in:

Open the T-Life app and tap Manage in the bottom bar.
Enter your T-Mobile ID and password and select Log in.
You’ll be prompted for verification. You can choose:
- Text message, or
- More options to reveal your security questions.
Select Next, and a verification code will be sent to your phone.
Enter the code and select Next to log in.

Check your T-Mobile data usage and plan details

Running out of high-speed data is frustrating, and even unlimited plans can slow down after a certain point. If your internet feels sluggish, it's usually because of network congestion (also known as deprioritization) or because you've hit your plan's high-speed data cap for the month.

The T-Life app lets you track your data, text, and call usage in real time. This helps you decide whether to upgrade for more high-speed data or downgrade to save money if you're not using your full allowance.

How to check your data usage on the T-Life app:

Open the T-Life app.
From the Home tab, tap Usage across the top menu.

You can find your data usage directly on the Home screen.

From the Manage tab, scroll down to People.
Select your line and tap Data usage to see your full history.
You can also see data usage by line when you choose the other lines under People.

Check your data usage by line under the Manage tab.

Get the same coverage for half the price

Tired of sky-high cell bills? You can get the same reliable T-Mobile coverage for a fraction of the price by switching to an MVNO (mobile virtual network operator) like Mint Mobile. These smaller carriers use T-Mobile's network but operate at a lower cost, passing the savings to you.

You can bring your current phone and get unlimited talk, text, and data for as low as $30/month. The switch is just as easy as changing your T-Mobile plan, making it a smart way to keep great service while lowering your monthly payment.

Add a line to your T-Mobile account

Adding a new line through the T-Life app is simple and can save you a trip to the store. Whether you're expanding to a family plan, setting up a kids line with parental controls, or adding a connected device like a smartwatch or tablet, you can handle it all from your phone.

Plus, you have the flexibility to either purchase a new device through T-Mobile or bring your own compatible device to save money.

Here’s how to add a line to your T-Mobile account in the app:

Open the T-Life app, and you can either:
- Tap the Shop tab and add a plan to your cart; or
- Tap the Manage tab in the bottom bar and select Add a person or device.

Click on the promotions or plans on the home page to add a line, or add it to your card in the Shop tab.

Select the type of device you want to add (phone, tablet, smartwatch, or connected device).
For a new phone line, tap Phone and choose to either Buy a new phone or Bring your own.
Review your current plan options and select the number porting option (Keep your number or Get a new number).
Enter your payment details and tap Submit order to activate the new line.

You’ll be able to activate your service immediately if you choose an eSIM, or you’ll have to wait for your physical SIM to arrive. Once your new line is activated, you can manage it directly from the app, including monitoring data usage, setting up parental controls for kids' lines, and adjusting plan features as needed.

Need a new phone that doesn’t break the bank?

T-Mobile offers deals on popular models like the latest iPhone, Samsung Galaxy, and Google Pixel to make them more affordable. Carrier promotions often include trade-in credits for your old device, installment plans with low upfront costs, or discounts when you add a line. This makes it easier to get a premium phone while keeping your monthly payment low.
