T-Mobile (TMUS) added 962,000 postpaid customers in Q4 with free cash flow surging 67% to $4.19B, while Vodafone (VOD) grew service revenue 5.4% organically but saw operating income fall 52.7% due to M&A charges. SK Telecom (SKM) surged 45% year to date with a 4.71% dividend yield trading at 17x forward earnings.

T-Mobile is executing on customer growth and cash generation, Vodafone is integrating acquisitions across multiple continents, and SK Telecom’s rally lacks recent earnings visibility to confirm fundamental improvement.

T-Mobile US (NASDAQ: TMUS), Vodafone (NASDAQ: VOD), and SK Telecom (NYSE: SKM) occupy the same sector but run three completely different businesses in three different competitive environments. With fresh earnings for two of them and a surging stock price for the third, now is a good moment to compare how each stacks up.

T-Mobile's Q4 2025 headline looked messy at first glance. EPS came in at $1.88 against a $2.42 consensus, but that miss was almost entirely driven by $390 million in severance and workforce transformation charges. Strip those out and the underlying business is strong. Postpaid phone net adds hit 962,000 in Q4, the best in the industry, capping a full year of 3.3 million postpaid adds. Free cash flow surged 67% year over year to $4.19 billion in the quarter alone.

New CEO Srini Gopalan set the tone on the call:

"In 2025, more new postpaid customers chose the Un-carrier than ever before...We see continued opportunity to eliminate customer pain points, introduce even more consumers to the Un-carrier ethos, and further extend our network leadership while accelerating our digital transformation to drive durable and outsized profitable growth."

Srini Gopalan, T-Mobile CEO

Vodafone's story is more complicated. Q3 FY26 service revenue grew organically at 5.4%, with the Three UK merger making the UK its second-largest market at 23% of group service revenue. Germany, still the biggest piece at 32% of group service revenue, grew just 0.1% year over year. CEO Margherita Della Valle noted the company is "on track to deliver at the upper end" of guidance, but operating income fell 52.7% year over year due to M&A-related non-cash charges, clouding the picture for casual observers.

SK Telecom is the wildcard. No recent earnings data is available, which is a real limitation. The stock has surged 45% year to date and trades at roughly 17x forward earnings, well below T-Mobile's multiple. The 4.71% dividend yield adds income appeal. But without visibility into recent results, it is hard to know whether the rally reflects genuine fundamental improvement or a broader sentiment shift in Korean equities.

For T-Mobile, the test is whether FY2026 guidance of $37.0B-$37.5B in adjusted EBITDA holds as integration costs from UScellular normalize. The $14.6 billion buyback authorization through December 2026 provides a real floor under the stock. Vodafone needs Germany to stabilize -- a single market representing nearly a third of service revenue growing at essentially zero is a structural problem no amount of UK momentum fully offsets. SK Telecom needs to show the earnings to justify its run.

T-Mobile is the most straightforward of the three from a fundamental standpoint. The business is executing, free cash flow is growing rapidly, and analyst consensus carries a target price of $268 against today's price near $218. Vodafone offers a higher dividend yield amid an ongoing multi-continent restructuring. SK Telecom trades at a lower forward multiple with a higher yield, though the lack of recent earnings data makes it difficult to assess whether the stock's run reflects fundamental improvement or broader sentiment shifts in Korean equities.

Wall Street is pouring billions into AI, but most investors are buying the wrong stocks. The analyst who first identified NVIDIA as a buy back in 2010 — before its 28,000% run — has just pinpointed 10 new AI companies he believes could deliver outsized returns from here. One dominates a $100 billion equipment market. Another is solving the single biggest bottleneck holding back AI data centers. A third is a pure-play on an optical networking market set to quadruple.
