Jul 28, 2026, 2:59 AM UTC · Primary ticker $TMUS

This 8-K filing discloses a widespread T-Mobile service outage affecting thousands of customers nationwide, including those on MVNOs using its network. The disruption led to a slight dip in T-Mobile's stock price and generated significant customer complaints, highlighting operational risks for the company.
