Kingsburg Area in California’s Central Valley Selected as Location for New T-Mobile Customer Experience Center

New Center Will Create 1,000 Jobs in Fresno County – Making T-Mobile One of the Largest and Highest-Paying Employers in the County

April 03, 2019

Bellevue, Washington and Overland Park, Kansas – April 3, 2019 –T-Mobile US (NASDAQ: TMUS) and Sprint Corporation (NYSE: S) today announced that they have chosen the Kingsburg area in Fresno County, Calif. as the location for their previously announced Central Valley Customer Experience Center (CEC), subject to the close of their merger to become the New T-Mobile. With the creation of more than 1,000 new jobs, the New T-Mobile will be one of the largest employers in the area. Employees at the CEC will earn wages on average over 50% higher than the average wages in Fresno County, which will also make the New T-Mobile one of the highest-paying employers in the area.

The Kingsburg area CEC will support the expanded deployment of T-Mobile’s innovative Team of Experts (TEX) service model, which provides customers direct personal access to a dedicated team of specialists when they call or message for assistance. The specialists work with local retail and engineering teams to address a wide variety of topics and tackle complex challenges for customers primarily based in California.

“The Kingsburg area in Fresno County is already home to a tremendous amount of innovation, diverse talent and great energy, which makes it a perfect fit for the New T-Mobile!” said T-Mobile and New T-Mobile President Mike Sievert. “Our new CECs will allow the New T-Mobile to expand the personalized service we give our amazing customers every single day as we continue to grow. We can’t wait to be a partner in the revitalized Central Valley. We’re really excited to join the greater Kingsburg community, add an amazing group of 1,000 employees to our Magenta family and get to work taking care of our customers!”

Kingsburg area CEC employees will benefit from the values that have made T-Mobile a company that is consistently recognized as a great employer year after year. The Un-carrier has earned nearly 60 national and local workplace awards in the last year alone, including Best Places to Work honors for parents, diversity, women, Hispanics, LGBTQ and more. T-Mobile’s care centers were recognized on best place to work lists 22 times in 2018 alone! In addition to great pay, the New T-Mobile will continue to offer employees the great benefits that T-Mobile offers today including stock grants, career development opportunities, college tuition assistance, a childcare subsidy benefit, paid parental leave and adoption/surrogacy benefits.

The New T-Mobile’s investment in Customer Experience Centers — including previously-announced new locations in the Greater Rochester area of New York and Overland Park, Kansas and expansion of other existing centers — will create up to 5,600 additional American jobs by 2021. The combined company will have 7,500 more customer care professionals in 2024 than the two stand-alone companies would have employed. The CECs are just one way the New T-Mobile will invest billions of dollars in job creation and infrastructure in the U.S. From the first day they combine, Sprint and T-Mobile together will employ more people in the U.S. than both companies would separately. Other investments will include building out a state-of-the-art, nationwide 5G network, delivering more competition and new choice to customers like in-home broadband, and opening new stores to an expanding customer base.

“It is exciting to see the growing trend of employers taking advantage of the workforce opportunities in the Central Valley. As Fresno County’s strong job growth indicates, this region is primed for investment. We are looking forward to more companies starting and expanding their businesses with a high-quality workforce who can work closer to home and avoid extended daily commutes,” said Lenny Mendonca, Chief Economic and Business Advisor to California Governor Gavin Newsom.

“The New T-Mobile merger creates an incredible opportunity for the Central Valley and for the Kingsburg area from the addition of 1,000 good paying jobs at the Customer Experience Center, and from new cellular and Internet coverage for our rural communities. Bringing Internet services to communities that have not had services, particularly low income, senior and disabled residents, impacts the quality of our schools, the growth of small businesses, and the health of our communities. The New T-Mobile provides an opportunity for the Central Valley to see technology driven economic growth by bridging this digital divide,” said California State Senator Anna Caballero, 12th District.

The completion of the combination remains subject to regulatory approvals and certain other customary closing conditions. Additional information regarding T-Mobile’s merger with Sprint can be found at: www.NewTMobile.com.

Winning the Global Race to 5G

by Dr. John Saw

Chief Technology Officer

April 04, 2019

There’s a lot of attention on the global race to 5G, and for good reason. If we can lead the world in deploying a nationwide 5G network, it is expected to generate $500 billion in economic growth and up to 3 million new jobs in the U.S. alone.1 The country that leads in 5G will be a global hub for innovation and investment, benefitting from a massive wave of growth in new technologies and services across all industries.

While we laud the notable progress the FCC has made with infrastructure reform and spectrum auctions, the United States cannot be complacent. We are proud that the 5G potential of our proposed merger with T-Mobile has already spurred progress in the U.S., but China remains the clear leader in the race to 5G with a number of critical advantages. Multiple independent reports show that without aggressive action, the U.S. will not overcome China’s progress.2

The proposed merger between T-Mobile and Sprint is vital to accelerating the deployment of a true nationwide mobile 5G network and allowing the U.S. to take a leadership position in 5G. The proposed merger can create a wireless company with the spectrum assets, scale, and financial wherewithal to propel the U.S. into a leading position worldwide. In turn, this new company will spur AT&T and Verizon to invest more in 5G, creating a highly robust and competitive 5G market.

Consider the following:

U.S. Lacks Abundant Fresh Spectrum for 5G: No U.S. carrier today has sufficient access to all three layers of spectrum (low, mid and high-band) needed for a true, nationwide mobile 5G network. But in China, the government can award spectrum to carriers as needed across all bands, and has proactively done so.

Mid-band spectrum in particular plays an essential role in providing capacity over a robust 5G footprint, and China’s operators have large amounts of unencumbered 2.6 GHz, 3.5 GHz and 4.5 GHz spectrum for 5G.



Combining the complementary low, mid and high-band spectrum assets of Sprint and T-Mobile will give the U.S. a carrier equipped with the three layers of spectrum needed to rapidly deploy a broad and deep nationwide mobile 5G network.

U.S. Lacks Infrastructure & Site Density: Today China Tower, the nationalized tower company which owns 96% of cell sites in China, has approximately 1.9 million sites. On the other hand, all of the wireless network operators and tower companies in the U.S. have only about 200,000 cell sites combined.3 China has been densifying its network at an unprecedented rate, with 350,000 new cell sites on air in the past three years, compared to less than 30,000 built in the U.S.

As New Street Research has pointed out, operators with dense 4G networks such as those in China, have a significant capacity advantage and low-cost path to 5G by simply adding 5G access points to their existing grid.

In contrast, all four U.S. wireless operators face higher costs for densification and more onerous bureaucratic hurdles despite recent regulatory progress and reforms made by the FCC.2



By combining network resources, Sprint and T-Mobile have a rare opportunity to rapidly launch a denser 5G network comprised of existing small cells and macro sites spanning the U.S.

The U.S. is Behind in 5G Capital Investment: It’s estimated that China has outspent the U.S. by $8-10 billion per year on its wireless networks since 2015.4 And in the next five years, China is projected to outspend U.S. operators by 50%.5 Meanwhile, a recent report from HBSC on the state of 5G deployment predicts no major increases in capital expenditures from U.S. mobile broadband operators in the next few years.6

With the merger of Sprint and T-Mobile, the new company plans to invest nearly $40 billion to combine complementary spectrum, cell sites and assets to deliver a nationwide 5G network sooner than otherwise possible. In turn, this investment will spur AT&T and Verizon to invest more in 5G and create a more robust, competitive 5G market.

New T-Mobile Will Maintain U.S. Leadership in 5G

U.S. carriers are good at marketing and eager to tout their 5G progress. Verizon and AT&T have even launched commercial 5G services, but take a closer look and you’ll see these deployments are extremely limited in geographic scope. As largely fixed point-to-point transmissions, these networks do not offer true mobility, nor do they have the capability to do so near-term. Verizon, relying solely on millimeter wave spectrum, is essentially creating hot spots in big cities, and it halted its 5G Home deployment which uses a proprietary standard. Meanwhile, AT&T is rolling out fake 5G by renaming its LTE Advanced network 5G E.

At Sprint, we’re proud of our upcoming launch of mobile 5G in the metro areas of nine cities this year, but we’ve made it clear that a merger with T-Mobile is the only path to quickly build a broad and deep nationwide 5G network.



The stakes are high and the race to 5G will determine where the next Google, Apple, Amazon and Uber of the world is created – here in the U.S. or abroad. Now is the time to face facts. U.S. wireless carriers simply do not have the spectrum resources, cell site density, or capital investment to lead the world in 5G. The merger of T-Mobile and Sprint will allow the U.S. to rapidly lead with a world-class nationwide 5G network that has the breadth and depth needed to fuel innovation and competition on a global stage.
