## What the business does

T-Mobile operates a nationwide fifth-generation (5G) wireless network and sells phone service under the T-Mobile, Metro by T-Mobile, Mint Mobile, and Ultra Mobile brands. Customers may pay for service after using it, pay in advance, or buy home internet through wireless or fiber connections; businesses and resellers can also buy network service. At June 30, 2026, T-Mobile reported 34.7 million postpaid billing accounts (June 30, 2026, high); in the second quarter of 2026 it added 277,000 postpaid accounts net of accounts that left (quarter ended June 30, 2026, high).

### How it makes money

- **Postpaid wireless and related service** (67.6% (quarter ended March 31, 2026)) — Customers generally receive service first and pay through recurring bills. This segment category includes branded postpaid service.
- **Wireless devices and equipment** (17.3% (quarter ended March 31, 2026)) — T-Mobile sells phones, tablets, wearables, internet gateways, and accessories. Qualified customers may pay for a device over time through installments.
- **Prepaid wireless service** (10.9% (quarter ended March 31, 2026)) — Customers pay in advance for service, including through Metro by T-Mobile, Mint Mobile, Ultra Mobile, and T-Mobile prepaid brands.
- **Wholesale wireless service** (3.0% (quarter ended March 31, 2026)) — Wireless service resellers pay for access to T-Mobile's network and sell service to their own customers.

### Products

- **Postpaid wireless plans** — Phone and connected-device plans billed after service is used, including Experience More, Experience Beyond, and Essentials.
- **Prepaid wireless plans** — Wireless service paid for in advance and sold under T-Mobile, Metro by T-Mobile, Mint Mobile, and Ultra Mobile.

- Business customers buying wireless and connected-device service under the T-Mobile for Business brand.
- Wireless service resellers that buy network access and sell service under their own brands.

### Competitors

- AT&T (T) — Wireless service and home internet, including fixed wireless and fiber connections.
- Verizon Communications (VZ) — Wireless service and home internet, including fixed wireless and fiber connections.
- Comcast (CMCSA) — Broadband internet and wireless plans sold alongside other communications services.

### What it depends on

- Wireless service depends on access to licensed radio spectrum. The Federal Communications Commission issues and renews licenses, and T-Mobile leases some spectrum, including spectrum in the 2.5 gigahertz band.
- T-Mobile relies on outside suppliers and service providers for devices and for products and services used to operate its business and network.
- Deutsche Telekom controls a majority of T-Mobile's voting power and the T-Mobile trademarks used in its business.

### What could go wrong

- Wireless carriers and broadband providers compete for customers through prices, promotions, network service, and bundled plans; losing customers can reduce service and device revenue.
- Cyberattacks, failures in T-Mobile's systems or network, or problems at outside providers could disrupt service or expose customer data.
- Spectrum is limited and costly to acquire, and changes to spectrum rules or failure to renew or retain licenses could affect T-Mobile's ability to provide wireless service.
