Forced Price Hikes:
T-Mobile abandoned its famous "Price Lock" guarantee and forcibly migrated millions of users on legacy plans to more expensive tiers. This triggered massive consumer backlash, regulatory scrutiny from the FCC, and a sharp spike in customer cancellations (churn) as price-sensitive subscribers walked away.
Opaque Reporting & Heavy Competition:
To mask slowing customer acquisitions, management stopped reporting key subscriber growth metrics. At the same time, they underestimated competitors; AT&T and Verizon matched promotions effectively, while cable operators (like Comcast and Charter) aggressively stole market share with hyper-cheap mobile and broadband bundles.
Flawed Digital Transformation:
In a bid to cut costs through automation, the company laid off over 4,500 employees, closed retail locations, and forced customers to use the digital T-Life app for upgrades. This severely disrupted the traditional customer service experience and alienated users who preferred in-person support during a highly competitive market cycle.
