NEW YORK, July 28, 2026, 05:40 EDT: T-Mobile US NASDAQ:TMUS has resolved a recent outage, but analysts say customer churn continues to represent the main challenge for the stock.
- T-Mobile reported that service to all customers was back online following Monday’s outage in the U.S. At its height, Downdetector recorded over 62,000 incident reports.
- The company has not revealed the reason or confirmed the number of affected customers.
- Initial market reading: a late quote indicated TMUS rising 0.8% to $178.55 ahead of the market open.
T-Mobile US reported that it had resumed service following a widespread outage across the United States late Monday. Regular U.S. trading had yet to begin, and the premarket quote appeared for roughly 1,060 shares.
Timing is significant. Reports of outages spiked at approximately 4 p.m. EDT, just before the market close. The 1.6% decline seen on Monday is not fully attributable to the outage.
The initial rise suggests few short-term financial worries. However, trading volume remained light. Market participants seem mainly attentive to retention rates and plan costs.
Downdetector registered upwards of 62,000 reports at the peak. Individuals in Arizona, California, Georgia, and Utah reported having access to SOS-only service. The platform relies on crowdsourced data and does not represent the precise number of users impacted.
T-Mobile announced full service restoration for all users, offering an apology. The company did not reveal the reason behind the issue and did not provide specific numbers on how many subscribers were affected.
U.S. telecom shares ended Monday with a sharper divergence.
| Company or index | Monday close | Daily move |
|---|---|---|
| T-Mobile US NASDAQ:TMUS | $177.21 | fell 1.60% |
| Verizon Communications NYSE:VZ | $47.32 | rose 2.03% |
| AT&T NYSE:T | $24.42 | increased 1.20% |
| S&P 500 | 7,413.18 | edged up 0.02% |
T-Mobile trailed its top two competitors by 3.2 percentage points compared to their average. As of the close on Monday, its shares had dropped 7.1% over five days. The downturn started ahead of the outage.
The carrier reported an increase of 277,000 postpaid accounts in the second quarter, representing a 13% decline from the same period last year. Account churn climbed to 0.99%, up from 0.92%.
The average monthly revenue per postpaid account increased by 2% to $152.91. Executives project net account additions of around 250,000 for the third quarter. Visible Alpha analysts were looking for about 304,000.
T-Mobile increased its adjusted free-cash-flow outlook to a range of $18.4 billion to $18.8 billion. That move helps ease worries about a recent isolated operational issue. The bigger issue is if service disruptions could contribute to higher expected customer churn.
Chief Operating Officer Jon Freier stated that premium plans make up “about 60% of total sales” for new customers. The drive for higher pricing is backed by reliability. However, another outage could undermine that strategy. Reuters
The 62,000-report high represents around 0.18% of T-Mobile’s 34.7 million postpaid subscribers. This figure serves only as a benchmark. Individual users might submit multiple reports, and numerous impacted subscribers do not report issues.
To provide background, Verizon’s outage in January led to over 1.5 million reports on Downdetector. Afterward, Verizon granted a $20 credit to impacted customers. On Monday, the number of T-Mobile reports was close to one twenty-fourth of Verizon’s figure.
Risks: The underlying issue has not been identified. Further failures, issues with emergency calls, regulatory scrutiny, or customer credits may increase expenses. Downdetector’s reporting might not fully capture the extent.
The key challenge for the stock at present is retention. Investors are expected to scrutinise third-quarter churn rates as T-Mobile transitions customers to higher-priced plans. A thorough technical analysis would be relevant.
