In an unprecedented move, T-Mobile has released its Q1 earnings without disclosing the crucial net new postpaid phone adds, a key metric analysts rely on to assess a wireless company’s performance. This marks a significant shift for T-Mobile as it emphasizes the importance of multi-line accounts over individual subscriber metrics.
Focus on Family and Business Accounts
T-Mobile is now prioritizing postpaid account additions for families and businesses, reflecting its strategic shift towards bundled services such as 5G wireless, home internet, and other offerings. In its latest report, T-Mobile announced an increase of 217,000 postpaid net new account additions, showing a 6% year-over-year growth. Moreover, the average revenue per account (ARPA) saw a rise of 3.9% from the previous year, reaching $151.93.
The Surge of Switchers to T-Mobile
T-Mobile attributes a record influx of new customers to the growing reputation for its network quality. The perception that T-Mobile’s network is improving constantly appears to be a significant driver for customers switching to the provider. According to CEO Srini Gopalan, the company is on a strong growth trajectory, achieving significant postpaid net account growth and bolstering postpaid ARPA, indicative of T-Mobile's successful strategy to attract and retain customers.
According to data from Ookla, T-Mobile holds the title of the fastest provider in Fixed Wireless Home Internet, boasting median download speeds over 50% faster than its closest competitor. The company reported a stable postpaid churn rate of 1.04%, remaining unchanged from the previous quarter, although it has increased slightly compared to the same period last year.
Transitioning into a Digital Era
T-Mobile is also transitioning into a digital-only carrier, with all transactions now managed through the T-Life app, including monthly invoice payments. This digital shift is expected to result in the reduction of physical stores and associated staffing costs, as T-Mobile seeks to streamline operations and enhance user experience.

For Q1 2026, T-Mobile reported an 11% increase in service revenue, totaling $18.8 billion, while postpaid service revenues jumped 15% year-over-year to $15.6 billion. However, net income dropped 15% to $2.5 billion due to costs associated with the merger with UScellular. The diluted earnings per share declined 12% year-over-year to $2.27.
T-Mobile has raised its forecast for postpaid net account additions for 2026 to between 950,000 and 1.05 million, an increase from the previous range of 900,000 to 1 million.
Market Response to Earnings Report
Following a sharp decline in stock value on Monday, T-Mobile’s shares rebounded on Tuesday, rising by $3.97 or 2.19% to $186.72. After-hours trading saw an additional increase of $3.09 or 1.65%, bringing the stock price to $189.81 once earnings were announced.
This quarter’s earnings report is significant as it marks the second announcement under the new CEO Srini Gopalan, who took over from Mike Sievert on November 1st.
