On July 30, T-Mobile US fell 3.4% in regular trading, trading at 176.04 USD/share, with turnover of $8.27 billion. The decline was triggered by a massive nationwide network outage that occurred on July 27.

The disruption affected over 64,000 users who submitted fault reports on monitoring platform Downdetector, spanning major cities including New York, Washington, Chicago, and Los Angeles. T-Mobile's virtual operators Mint Mobile and Boost Mobile were also impacted. Affected iPhone devices displayed SOS icons in their status bars, indicating complete loss of cellular connectivity, with users unable to make calls, send texts, or use data services. The outage lasted approximately 8 hours before T-Mobile announced service restoration, though some users continued to report connectivity issues.

The incident comes shortly after T-Mobile reported Q2 EPS of $2.99, beating consensus estimates of $2.58 by nearly 16%, and raised its full-year adjusted free cash flow guidance to $18.4-$18.8 billion. The network reliability concern appears to have offset recent earnings momentum.
