How T-Mobile Makes its Money: Revenue Breakdown (2024)

How Does T-Mobile Make its Money?

T-Mobile US, Inc. (NASDAQ: TMUS) generated $81.4 billion in total revenue in fiscal year 2024 — essentially flat (+0.6%) versus 2023’s $80.9 billion — but that headline number is deliberately misleading about the health of the business. Total revenue flatness was caused entirely by a planned -17.8% decline in equipment revenue (device sales), which is low-margin and intentionally de-emphasized. Service revenue — the recurring, high-margin core of the business — grew +5.7% to $65.8 billion, making T-Mobile the fastest-growing major wireless carrier in America in 2024 by the metric that actually matters to investors and to management. Net income grew from $8.3 billion to $11.2 billion (+35%), and free cash flow reached $17.0 billion — a staggering figure for a company that was nearly unprofitable before the Sprint merger.

T-Mobile is the largest wireless carrier in the United States by postpaid phone net additions — the most competitive metric in the industry — having led the country in subscriber growth every single year from 2013 through 2024. The company serves over 125 million customers across postpaid, prepaid, and wholesale lines of service, operating under the T-Mobile and Metro by T-Mobile brands.

The modern T-Mobile was built through two transformational events: (1) the “Un-carrier” repositioning beginning in 2013 under CEO John Legere, which systematically dismantled wireless industry conventions (no annual contracts in 2013, unlimited data in 2017, no more overage fees) to drive explosive subscriber growth, and (2) the 2020 Sprint merger — a $26.5 billion deal that combined the third- and fourth-largest U.S. carriers, gave T-Mobile access to Sprint’s valuable mid-band spectrum (critical for 5G), and created ~$8 billion in annual synergies that transformed T-Mobile’s margin and free cash flow profile permanently. Under current CEO Mike Sievert (who succeeded Legere in 2020), T-Mobile has shifted from disruptive challenger to profitable incumbent while continuing to grow faster than Verizon and AT&T.

T-Mobile’s core business is simple: customers pay a monthly fee to access T-Mobile’s wireless network. Service revenue is 81% of total revenue. The remaining 19% from equipment (phones and devices) is nearly break-even in terms of profit — it exists to remove friction from the customer relationship (trading in old phones, upgrading devices) rather than as a standalone revenue driver.

Key Takeaways

• $81.4B in total revenue (2024) — the headline is flat (+0.6%), but this masks strong underlying business momentum; service revenue (the recurring, profitable part) grew +5.7%; equipment revenue (low-margin, intentionally declining) fell -17.8%; investors and analysts focus exclusively on service revenue as the health metric; T-Mobile consistently communicates this distinction in earnings calls and investor presentations
• Service revenue of $65.8B growing at +5.7% — faster than Verizon’s service revenue growth (~+2–3%) and AT&T’s service revenue growth (~+3–4%) in 2024; the Un-carrier brand continues to attract subscribers despite T-Mobile now being the largest carrier by postpaid net additions; this persistent market share gain from a position of market leadership is unusual in mature industries and reflects T-Mobile’s structural 5G network advantage
• Net income of $11.2B — up +35% YoY — dramatic improvement from $8.3B in 2023; the Sprint merger synergies of ~$8B annually are now fully realized, meaning margin improvement going forward must come from revenue growth and operational efficiency rather than cost cuts; operating margin reached 20.4%, the best among U.S. wireless carriers; T-Mobile’s margin transformation from pre-merger (~10% operating margin) to post-merger (20.4%) is one of the most successful telecom turnarounds in industry history
• Free cash flow of $17.0B — exceptional for a capital-intensive business; wireless carriers are historically heavy capex spenders (building and maintaining cell tower infrastructure, paying spectrum license fees, upgrading networks); T-Mobile’s FCF generation reflects fully realized merger synergies, a maturing capital expenditure cycle (the 5G network buildout is largely complete), and operating leverage on a growing service revenue base; $17B in annual FCF funds an aggressive $19B+ share buyback program and positions T-Mobile as a capital return story for 2025–2027
• 6.2 million fixed wireless access (FWA) subscribers — T-Mobile’s home internet product (T-Mobile Home Internet) uses its 5G network to provide home broadband service without cable or fiber infrastructure; 6.2M subscribers makes T-Mobile the third-largest home internet provider in the U.S., behind only Comcast and Charter, despite having launched the product less than 5 years ago; this is the most significant new revenue stream in U.S. wireless, with potential to reach 7–8M subscribers by 2026 and $4–6B in annual service revenue
• Postpaid phone churn of 0.86% — industry-leading customer retention; churn is the fundamental health metric for wireless carriers; 0.86% monthly churn means T-Mobile loses fewer than 1 in 115 postpaid phone customers per month; this level of churn is achieved through a combination of network quality (T-Mobile’s mid-band 5G is consistently rated the fastest U.S. 5G network by independent testers including Ookla and OpenSignal), competitive pricing, and the stickiness of multi-line family plans where multiple family members are on the same account
• 5.6 million total net subscriber additions in 2024 — more than Verizon and AT&T combined; postpaid phone net additions alone (the highest-value subscriber type) exceeded Verizon and AT&T’s combined phone net additions; T-Mobile’s 5G network quality advantage is the primary driver — when customers consider switching carriers, T-Mobile’s consistently superior download speeds (particularly in suburban and rural areas where mid-band 5G has stronger coverage than Verizon’s mmWave-heavy approach) drive a measurable share of switching decisions toward T-Mobile

T-Mobile (TMUS) Business Model

T-Mobile’s business model is a classic subscription services model operating in a capital-intensive infrastructure industry. The economics work as follows:

Revenue Sources (Ranked by Strategic Importance)

The wireless subscription unit economics:

A T-Mobile postpaid phone customer paying $70/month generates $840/year in service revenue. The marginal cost to serve that customer (network capacity consumed, customer service contacts, billing) is approximately $250–300/year. Gross margin per subscriber: ~$550–600/year, or 65–70%. The primary fixed costs — cell tower infrastructure, spectrum licenses, backhaul, network maintenance, and capex — are shared across all 125M+ customers, creating strong operating leverage: as T-Mobile adds subscribers, incremental service revenue flows through at high margins.

The equipment business is a customer acquisition and retention tool, not a profit center:

T-Mobile sells or finances smartphones at near-cost or at a loss (subsidized by trade-in credits and promotional pricing) because device upgrades lock customers into multi-year installment payment plans (EIP — Equipment Installment Plans) and service agreements. A customer who just upgraded to a new iPhone on a 36-month EIP with T-Mobile is highly unlikely to switch carriers before completing the payment plan. Equipment revenue is therefore best understood as a customer retention mechanism with a low-margin income statement footprint.

Why the Sprint merger was strategically decisive:

Sprint owned enormous quantities of mid-band spectrum (2.5 GHz band) — electromagnetic frequency that provides an ideal balance of coverage range and data capacity for 5G networks. Verizon’s early 5G bet on millimeter wave (mmWave) spectrum provides extraordinary speeds but extremely limited range (effective only indoors and in dense urban environments within blocks of a tower). AT&T’s 5G used lower C-band frequencies with good range but lower speeds. T-Mobile’s Sprint mid-band spectrum enabled a 5G network that delivers genuinely fast speeds (typically 200–400 Mbps median download) across broad coverage areas including suburbs and rural markets — a technical advantage that translates directly into lower churn and higher net additions as customers discover the quality difference.

T-Mobile Competitors

T-Mobile competes against two national wireless carriers and a growing set of virtual network operators:

National wireless carriers:

• Verizon — historically the premium wireless network; Verizon’s mmWave 5G is the fastest available in dense cities but has negligible suburban/rural coverage; Verizon has been losing postpaid phone net additions to T-Mobile for years and is now focused on business/enterprise customers and fixed wireless broadband as growth vectors; see AT&T vs Verizon for a direct comparison of the two largest traditional carriers
• AT&T — AT&T sold DirecTV (2021) and WarnerMedia (2022) to refocus entirely on connectivity (wireless + fiber); AT&T Fiber is the most serious fiber broadband competitor in overlapping markets; AT&T’s postpaid wireless growth has improved (+3–4% service revenue growth) but trails T-Mobile; AT&T’s enterprise segment (FirstNet — dedicated wireless network for first responders) is a genuine competitive advantage T-Mobile lacks

Fixed wireless broadband competition:

• Comcast — the dominant cable broadband provider; T-Mobile FWA directly competes with Comcast’s Xfinity Internet product; Comcast’s fiber-coaxial cable infrastructure delivers higher and more consistent throughput than T-Mobile’s wireless FWA (particularly at peak usage times), but T-Mobile’s competitive pricing ($50/month vs. Comcast’s typical $80–110/month with various fees) is driving meaningful FWA subscriber growth in cable service areas; Comcast has responded by launching Comcast Mobile (an MVNO running on Verizon’s network) to retain customers with a bundle offer

Mobile virtual network operators (MVNOs):

• MVNOs like Mint Mobile (now owned by T-Mobile itself), Tracfone (Verizon), Cricket Wireless (AT&T), and Boost Mobile compete primarily in the prepaid segment; most major MVNOs run on one of the three national networks’ infrastructure, making network quality parity available at lower price points — a competitive pressure on T-Mobile’s prepaid segment specifically

Revenue Breakdown

Financial data sourced from T-Mobile 2024 Annual Report (10-K).

Postpaid Service Revenue — 64% of Total, the Core Business

Postpaid service revenue of $52.4 billion (+6.6%) is the primary engine of T-Mobile’s value creation. Postpaid customers pay monthly in arrears after service is rendered — these are the highest-quality wireless subscribers by every metric:

• Lower churn (0.86%/month vs. ~2–3%/month for prepaid) because they have monthly billing relationships and often multi-device family plans
• Higher ARPU (Average Revenue Per User) — postpaid phone ARPU is approximately $49–50/month vs. ~$35/month for prepaid
• More add-on revenue — postpaid customers more frequently buy device protection plans, international roaming add-ons, tablet lines, and smartwatch lines

ARPU growth has been a quiet driver of postpaid revenue growth alongside subscriber additions. T-Mobile’s “Go5G” plan family (introduced in 2023) carries higher prices than predecessor plans, and existing customers migrating from older, cheaper plans to newer plans (sometimes driven by T-Mobile’s selective legacy plan price increases) add revenue without subscriber count changes.

Fixed Wireless Access contribution to postpaid service: T-Mobile’s FWA product (T-Mobile Home Internet) generates service revenue counted within the postpaid category. With 6.2M FWA subscribers at ~$50/month average, FWA contributes approximately $3.7B annually to postpaid service revenue — approximately 7% of postpaid service revenue and growing rapidly as T-Mobile guides toward 7–8M FWA subscribers by 2026.

Prepaid Service Revenue — 12% of Total

Prepaid revenue of $9.8B (+2.1%) comes primarily from Metro by T-Mobile, T-Mobile’s prepaid brand. Prepaid revenue growth is structurally slower than postpaid due to lower ARPU and higher churn in the prepaid segment. Metro by T-Mobile is the leading prepaid brand in the U.S. by subscriber count and benefits from T-Mobile’s network quality — prepaid customers on Metro have access to the same 5G network as T-Mobile postpaid customers, a quality advantage over competing prepaid brands running on Verizon’s or AT&T’s networks.

Wholesale & Other Service — 4% of Total

Wholesale revenue of $3.6B (+11.9%) comes from mobile virtual network operators (MVNOs) and other carriers that pay T-Mobile to use its network infrastructure. This is the highest-margin service revenue T-Mobile generates — MVNOs pay for network capacity and T-Mobile incurs only marginal additional network costs to serve them. Growing wholesale revenue reflects T-Mobile’s network quality and capacity attracting more MVNO partners.

Equipment Revenue — 19% of Total, Managed Decline

Equipment revenue declined from $19.0B to $15.6B (-17.7%). This decline is intentional and reflects T-Mobile’s strategic pivot away from device subsidies toward service-value competition. The smartphone upgrade cycle has also lengthened — customers are keeping phones longer — reducing device transaction volume industry-wide. Equipment revenue at $15.6B is approximately break-even in terms of gross profit; it exists as a service to customers rather than a profit center.

Revenue Trend (3-Year)

The trend shows what truly matters: service revenue compounding at 6–9% annually while net income and FCF grow dramatically faster (operating leverage). The $2.6B net income in 2022 vs. $11.2B in 2024 reflects the merger synergy capture being recognized in financial results — the same revenue base generating dramatically more profit as Sprint integration costs are retired and duplicated infrastructure is eliminated.

T-Mobile (TMUS) Income Statement

Gross margin expansion (+500bps to 62.9%) driven by equipment revenue decline (low-margin) being replaced in mix by higher-margin service revenue growth — this is the clearest demonstration of why equipment revenue decline is financially healthy for T-Mobile’s margin profile.

Operating income grew +19.1% on +0.6% total revenue growth — the leverage story illustrated; the $19.3B operating income figure is materially higher than the $17.0B FCF because D&A of $16.5B is a non-cash operating expense (capitalized network infrastructure being expensed over time); actual cash generation is represented by FCF.

T-Mobile (TMUS) Key Financial Metrics

• Service Revenue CAGR (2022–2024): ~7.2% — consistent, above-market-rate growth in the most important revenue metric; T-Mobile has guided for continued service revenue growth of 5–6%+ through 2027; at $65.8B base, each 1% of service revenue growth = ~$658M in incremental high-margin revenue

• Free Cash Flow: $17.0B — $17B FCF on $81B revenue is a 20.9% FCF margin; for context, Verizon generates approximately $18–19B FCF on $134B in revenue (14% FCF margin); T-Mobile’s FCF margin is structurally higher because merger synergies reduced cost base and the network capex cycle has peaked; management guides $17B+ in FCF through 2027

• Operating Margin: 23.7% (2024) — best among U.S. wireless carriers; Verizon’s operating margin ~22%; AT&T’s ~22–23%; T-Mobile’s superior operating margin reflects fully integrated Sprint operations and a lower legacy cost structure; the margin gap is likely to persist or widen as T-Mobile’s service revenue grows faster

• Gross Margin: 62.9% — the 500bps expansion from 2023 reflects a favorable mix shift toward service revenue (higher margin) and away from equipment revenue (near-zero margin); as FWA subscribers grow and equipment revenue continues to decline, gross margin expansion should persist

• Postpaid Phone ARPU: ~$49–50/month — ARPU has been gradually rising through plan mix upgrades (Go5G plans priced above legacy plans), selective legacy plan price adjustments, and growing add-on attach rates; each $1/month of ARPU expansion across ~100M postpaid phone subscribers = ~$1.2B in incremental annual service revenue

• Net Subscriber Additions: 5.6M total (2024) — includes postpaid phone, prepaid, FWA, and other lines; postpaid phone net additions of approximately 3.1M led the industry; T-Mobile has led U.S. wireless in postpaid phone net additions every year since 2013 — an unprecedented 12-year streak in a mature competitive market

• Postpaid Phone Churn: 0.86%/month — the gold standard for customer retention in wireless; Verizon postpaid phone churn is typically ~0.90–0.95%; AT&T’s ~0.92–0.98%; T-Mobile’s churn advantage is the compounded result of network quality, value-for-money positioning, multi-line family plan stickiness, and the EIP installment plan lock-in dynamic

Fixed Wireless Access: T-Mobile’s Second Business

Fixed Wireless Access (FWA) is T-Mobile’s home internet product — a wireless router placed in a customer’s home receives 5G signal from T-Mobile’s network and broadcasts home Wi-Fi throughout the residence. No cable, no fiber, no installation appointment. The product costs $50/month (T-Mobile customers) to $65/month (non-T-Mobile customers), compared to cable internet plans typically priced at $80–110/month.

The 2024 FWA scorecard:

• 6.2 million FWA subscribers at year-end 2024 (vs. 5.0M at end of 2023, +24%)
• ~$3.7B estimated annual FWA service revenue run-rate
• FWA now adds more net customers per quarter than AT&T’s entire fiber broadband business
• T-Mobile guides 7–8M FWA subscribers by end of 2026

Why FWA is strategically significant:

The U.S. home broadband market is enormous — approximately 110 million households pay for home internet service. Historically controlled entirely by cable and telephone companies (Comcast, Charter, AT&T Fiber, Verizon Fios), wireless carriers had no competitive product. T-Mobile’s mid-band 5G network — with sufficient capacity from Sprint’s spectrum and its own additional spectrum purchases — enables a genuine competitive broadband product in most suburban and rural markets. FWA does not compete well in dense urban environments (where network congestion limits throughput), but in the suburban markets where cable companies have faced essentially zero competition for decades, T-Mobile FWA is a meaningful disruptor.

FWA financial economics: At $50–65/month per subscriber and near-zero incremental infrastructure cost (FWA customers use existing network capacity), FWA generates some of the highest gross margins in T-Mobile’s portfolio. The network capacity that would otherwise be underutilized in residential neighborhoods is monetized through FWA subscriptions — a capital-efficient revenue stream.

The Sprint Merger: By the Numbers

The $26.5 billion Sprint merger (closed April 2020) is the defining financial event in T-Mobile’s history:

Annual synergies: ~$8B/year now fully realized, comprising network cost savings (decommissioning duplicate Sprint cell towers), overhead reduction (eliminating redundant Sprint corporate functions), spectrum efficiency gains (using Sprint spectrum on T-Mobile’s superior infrastructure), and customer base migration (moving Sprint customers onto T-Mobile’s network at lower cost-to-serve). The synergy realization is the primary explanation for the dramatic increase in operating income and FCF from 2020 to 2024.

Is T-Mobile Profitable?

Yes — emphatically. T-Mobile generated $11.2 billion in net income (13.7% net margin) and $17.0 billion in free cash flow in fiscal year 2024. Both figures grew dramatically from 2023 ($8.3B net income, $13.6B FCF) and from 2022 ($2.6B net income, $7.2B FCF), reflecting the full realization of Sprint merger synergies and the operating leverage inherent in a subscription services business with a largely fixed-cost infrastructure. T-Mobile has deployed its FCF into an aggressive shareholder return program: a $19B+ share repurchase authorization and initiation of a quarterly dividend in 2024.

What to Watch

1. FWA subscriber trajectory and ARPU — the most important new growth metric; management guidance of 7–8M FWA subscribers by 2026 implies continued +20%+ growth; watch quarterly FWA net additions and whether T-Mobile moves FWA pricing higher as the product matures and competition from cable fiber buildouts intensifies; also watch whether FWA customers bundle T-Mobile wireless (important for churn reduction and ARPU uplift)

2. Postpaid ARPU acceleration — T-Mobile has been cautious about price increases to preserve its value-brand positioning; there is meaningful ARPU upside if T-Mobile selectively raises prices on legacy plan holders (as it has done in small increments since 2022); each $1/month increase across ~100M subscribers = ~$1.2B in annual service revenue; watch quarterly ARPU disclosures for trend direction

3. Enterprise and business wireless penetration — T-Mobile’s weakest competitive segment; Verizon and AT&T dominate large enterprise wireless contracts (government, Fortune 500) due to decades of relationship depth, dedicated enterprise sales teams, and specialized products like AT&T’s FirstNet; T-Mobile’s share of enterprise wireless is 15–20% (below its 30%+ consumer share); each 1% of market share gain in enterprise wireless = ~$1–2B in high-value service revenue; watch for major enterprise contract announcements

4. Capital return execution — with $17B+ in annual FCF and a $19B+ buyback authorization, T-Mobile is in capital return mode; watch share count reduction (lower diluted shares = higher EPS growth even without revenue acceleration) and dividend growth trajectory; the capital return program is a floor on the investment thesis if revenue growth were to slow

5. Spectrum policy and 6 GHz/Upper C-band auctions — T-Mobile’s mid-band 5G advantage is durable but not permanent; future spectrum auctions (FCC has proposed 6 GHz and additional C-band bands) will allow Verizon and AT&T to potentially close the mid-band spectrum gap; watch regulatory decisions on spectrum allocation and T-Mobile’s auction participation strategy; if the mid-band advantage erodes, the churn advantage and subscriber growth leadership could moderate

6. Starlink / LEO satellite competition — SpaceX Starlink and other low-earth orbit satellite internet providers have begun offering broadband service; while Starlink’s latency (20–40ms) and pricing ($120/month) position it above T-Mobile FWA for most residential users today, next-generation satellite products could threaten T-Mobile FWA’s rural market position specifically; T-Mobile has proactively partnered with SpaceX on a direct-to-cell satellite feature for standard T-Mobile phones — a defensive positioning move

T-Mobile (TMUS) Financial Summary

T-Mobile US, Inc. (NASDAQ: TMUS) is the largest U.S. wireless carrier by subscriber growth, generating $81.4 billion in total revenue and $65.8 billion in service revenue (+6.2%) in fiscal year 2024. Net income of $11.2 billion (+34.3%) and free cash flow of $17.0 billion reflect Sprint merger synergies now fully embedded in the cost structure, industry-leading operating margins (23.7%), and the operating leverage of a subscription services business on a fixed-cost 5G network. T-Mobile’s 6.2 million FWA subscribers (+24% YoY) make it the fastest-growing home internet provider in the country, disrupting cable incumbents like Comcast with lower-priced wireless broadband. The bull case rests on continued service revenue compounding at 5–7%, FWA reaching 8–10M subscribers, enterprise wireless share gains, and $17B+ annual FCF deployed into buybacks and dividends. Key risks: network quality advantage narrowing as Verizon and AT&T acquire mid-band spectrum, postpaid phone market saturation limiting net addition volumes, and macroeconomic pressure on consumer wireless spending.
