1. Subscriber Growth
In the fourth quarter, T-Mobile US reported 2.4 million postpaid net customer additions and 261,000 postpaid account gains, marking its strongest subscriber momentum. Postpaid phone net additions reached 962,000, while retail postpaid churn remained low at 1.02%, underscoring healthy retention.
2. Revenue Performance
Total service revenues climbed 10.7% year over year to $18.7 billion, up from $16.9 billion in the prior-year period. Growth was driven primarily by subscriber expansion rather than ARPU inflation, reflecting effective pricing strategies and competitive offers.
3. 5G Leadership
T-Mobile’s Ultra Capacity 5G network continues to fuel demand, delivering superfast speeds for smartphones and enterprise use cases. The technology’s rapid rollout has strengthened customer uptake and contributed materially to both subscriber adds and revenue growth.
4. Competitive Position
T-Mobile maintains a leadership position in the saturated U.S. wireless market, outpacing churn metrics of peers. Its combined 5G and bundled service offerings create higher switching friction, enhancing customer stickiness against Verizon and AT&T competition.
