T-Mobile says the strength of its fifth-generation (5G) wireless network attracted millions of new customers during 2024 — and, now, it’s making an aggressive play for those who subscribe to AT&T FirstNet.
On Wednesday, the wireless company disclosed 263,000 postpaid net account additions and 1.9 million postpaid net customer additions during the fourth financial quarter (Q4) of the year, helping to bring its year-end total to 1.1 million postpaid net account additions and 6.1 million net customer additions.
The company does not disclose what it considers to be an “account” versus a “customer,” but the data related to customer is expected to correlate with the number of new activation or additional lines of service on an account. T-Mobile is known to gift free lines of service to some long-term customers; it isn’t clear if those free lines are counted as new customer additions in its quarterly and annual earnings reports. Accounts and customers include wireless phone, fixed wireless home Internet, tablet, hotspot and smartwatch services.
Postpaid phone net customer additions were 903,000 during Q4 and 3.1 million in 2024, the company said. T-Mobile’s wireless phone service is the biggest part of its domestic business.
Service revenue grew to $16.9 billion during Q4 and $66.2 billion during the year, which the company touted as “industry-leading growth.” Revenue attributed to its various postpaid services increased to $13.5 billion in Q4 and $52.3 billion during 2024, beating Wall Street estimates. Diluted earnings per share (EPS) clocked in at $2.57 in Q4 and $9.66 in 2024, the highest in T-Mobile’s history.
“By putting customers first, T-Mobile delivered another monster Q4 that punctuated an amazing growth year with best-in-class results across wireless and broadband,” Mike Sievert, the CEO of T-Mobile, said in a statement. “In 2024, more new postpaid customers chose the Un-Carrier than ever before, and we had our lowest ever full-year postpaid phone churn, leading to our third year of more than 3 million postpaid phone net additions.”
“Now, building on this incredible momentum, 2025 is poised to be even more exciting, and because of this, we’re issuing the strongest start-of-year postpaid net additions guide in our history,” Sievert continued. “We’ve already hit the ground running on our ambitious plans to give customers the kind of new, transformative experiences no one else can, and we’re just getting started.”
On a conference call with investors and reporters, Sievert called T-Mobile “the most-successful telecom in the world” based on “some measures,” and said the company still had “many incredible capabilities around incredible data…and network capabilities,” which gives the carrier “room to run in terms of creating new services around them.”
One of those initiatives is T-Priority, which allows first responders like police, firefighters, paramedics and others priority access to T-Mobile’s network during times of severe network congestion.
“With T-Priority, we’re able to present to first responders 40 percent more capacity and two-and-a-half times the speed,” Callie Field, the President of T-Mobile Business, said on the call. “And, in a time of extreme congestion, we’re able to allocate more than five times the network resources than we do to the average consumer.”

T-Priority is clearly a play to attract first responders away from FirstNet, the public-private partnership developed by AT&T and backed by the U.S. Congress in the mid-2010s. Like T-Priority, AT&T is exclusively available to eligible first responders, and gives those individuals and agencies priority access to AT&T’s 4G LTE and 5G wireless networks.
T-Priority isn’t backed by the government, but the company is still hoping to attract first responders by promising them an exclusive 5G network slice that offers baseline data transfer speeds that are “two times faster than our historical baseline for first responders,” the company affirmed in marketing materials.
“Think of it as a ticket to a unique experience on our robust 5G network that is dedicated to first responders,” T-Mobile’s marketing material says.
T-Mobile says it can promise priority 5G data access to first responders because, of the three major carriers in the U.S., it is the only one to operate a standalone 5G wireless network. By comparison, AT&T and T-Mobile deliver enhanced 5G service using their legacy 4G LTE wireless core, though Verizon does operate a standalone 5G Ultra-Wideband core in some major cities.
