How Does T-Mobile Make its Money?

T-Mobile US is the largest wireless carrier in the United States by subscriber count, serving over 125 million customers. The company completed its transformational merger with Sprint in 2020, combining the third and fourth-largest U.S. carriers into a formidable competitor to Verizon and AT&T.

T-Mobile’s “Un-carrier” brand positioning — focused on eliminating industry pain points like contracts, hidden fees, and data caps — helped it gain massive market share over the past decade. The Sprint merger gave T-Mobile access to valuable mid-band 5G spectrum, which allowed it to build what many consider the best nationwide 5G network.

Revenue Breakdown

Revenue Source 2024 2023 YoY Growth
Postpaid Service Revenue $52.4B $49.2B +6.5%
Prepaid Service Revenue $9.8B $9.6B +2.1%
Wholesale & Other Service $3.8B $3.4B +11.8%
Equipment Revenue $15.2B $18.5B -17.8%
Total Revenue $81.4B $80.9B +0.6%

Postpaid Service Revenue — 64% of Revenue

The crown jewel. Postpaid customers (who pay monthly after service is rendered) are the most valuable wireless subscribers — they have lower churn, higher average revenue per user (ARPU), and more predictable cash flows. T-Mobile’s postpaid phone customer base grew by approximately 3.6 million net additions in 2024, leading the industry. ARPU has been increasing through plan upgrades, add-on services, and price adjustments.

Prepaid Service Revenue — 12% of Revenue

Prepaid customers pay in advance for service. T-Mobile operates prepaid brands including Metro by T-Mobile and the legacy Sprint prepaid base. Growth is modest as this is a more competitive, price-sensitive segment.

Wholesale & Other Service — 5% of Revenue

Revenue from mobile virtual network operators (MVNOs) and other carriers that use T-Mobile’s network. Growing as T-Mobile’s superior 5G network attracts wholesale partners.

Equipment Revenue — 19% of Revenue

Sales and leases of smartphones and other devices. Revenue declined as the smartphone upgrade cycle lengthened and promotional activity shifted toward service-based incentives rather than device discounts. Equipment is a low-margin or break-even business for all wireless carriers.

Key Financial Metrics

  • Service Revenue Growth: +5.7% — Wall Street focuses on service revenue (excluding equipment) as the true measure of wireless growth. T-Mobile’s 5.7% service revenue growth is industry-leading.
  • Operating Margin: 20.4% — T-Mobile now has the best operating margins among U.S. wireless carriers, a dramatic improvement from the pre-merger era when it operated at much lower profitability.
  • Free Cash Flow: $17.0B — T-Mobile has become a free cash flow powerhouse. Sprint merger synergies (~$8B annually) and operational efficiency drove massive cash generation.
  • Postpaid Phone Churn: ~0.86% — Industry-leading customer retention. T-Mobile’s network quality and value proposition keep customers loyal.
  • Net Subscriber Additions: 5.6M total — T-Mobile continues to add more customers than Verizon and AT&T combined, driven by 5G network quality and competitive pricing.

What to Watch

  1. 5G monetization — T-Mobile has the largest 5G network in the U.S. Monetizing this through higher-tier plans, fixed wireless broadband, and enterprise solutions is the next growth chapter.
  2. Fixed wireless access (FWA) — T-Mobile’s home internet service (using 5G) has already attracted over 6 million subscribers, disrupting cable companies. The FWA market could be a $10B+ revenue opportunity.
  3. Capital returns — With massive free cash flow and diminishing capex needs post-network buildout, T-Mobile has been aggressively buying back stock (~$19B authorized). Shareholder returns are a key part of the investment thesis.
  4. Industry consolidation/saturation — The U.S. wireless market is maturing. Subscriber growth must eventually slow, shifting the focus from customer acquisition to ARPU growth and new services.
  5. Enterprise and government — T-Mobile is the weakest of the three major carriers in the enterprise segment. Winning more business customers could meaningfully expand the addressable market.
