T-Mobile #1 in Customer Satisfaction Throughout 2017

January 04, 2018

Two independent studies show Un-carrier customers are happiest all year long, as LTE speed and coverage increased

Bellevue, Washington — January 3, 2018 — T-Mobile (NASDAQ: TMUS) is schooling the competition … again! The Un-carrier scored top marks in customer satisfaction – ALL YEAR LONG in 2017, according to two major independent studies. T-Mobile consistently ranked #1 in Overall Customer Satisfaction and Likelihood to Recommend1 in 2017 according to the latest national survey from the leading consumer opinion tracker, which surveys more than 360,000 mobile phone customers annually. And, if one source isn’t enough for ya, the leading global polling and research firm YouGov BrandIndex just reported that T-Mobile customers were consistently more satisfied than carrier customers throughout 2017.

And, it’s no wonder. The news comes as T-Mobile announced today that the Un-carrier has significantly expanded its LTE network to cover 322 million people, up from 315 last year, bringing coverage to entirely new places. In fact, T-Mobile has lit up its new 600 MHz spectrum at breakneck speed, and it’s already live in 586 cities and towns. In 2018, T-Mobile will launch more than a dozen new 600 MHz capable smartphones, ranging from budget-friendly phones to superphones.

"The secret for having the happiest customers isn’t a secret at all. I’ve been yelling about it for years! Listen to customers, fix their pain points, give them a great deal and awesome coverage. You’d think even Dumb and Dumber would get it by now,” said John Legere, president and CEO of T-Mobile. “Our customers may be happy – but I won’t be until we’ve completely changed this broken industry for good! There’s still so much to fix!”







T-Mobile surpassed its aggressive commitment to reach 321 million people with LTE in 2017. The Un-carrier has nearly tripled its LTE coverage since 2015 and now covers 99% as many people as Verizon. In addition to broad coverage, T-Mobile’s LTE network consistently delivers the fastest actual customer download and upload speeds in the industry, with speeds only continuing to increase. In fact, T-Mobile’s LTE network just ranked fastest for the 16th quarter in a row – four straight years –according to Speedtest by Ookla.

“The LTE coverage gap between T-Mobile and Verizon is a thing of history,” said Neville Ray, Chief Technology Officer for T-Mobile. “Any small difference that exists will rapidly disappear as we accelerate expansion into rural America. We’re just getting started with the 600 MHz low-band spectrum we’re rolling out now, and it’s a wide-open highway for customers, increasing coverage, capacity and in-building reach.”

T-Mobile expanded its LTE network in 2017 by completing several major 700 MHz deployments and aggressively deploying its newly acquired 600 MHz spectrum. T-Mobile completed in just six months a task that is typically a two-year process from spectrum auction close to customer availability, and continues to roll out 600 MHz LTE coverage at a record-setting pace.

600 MHz spectrum will expand T-Mobile’s LTE footprint even further while laying the foundation for the country’s first nationwide 5G network. T-Mobile owns a staggering 31 MHz on average of 600 MHz spectrum licenses that can cover every single American with low-band spectrum, which travels twice as far and is four times better in buildings than mid-band spectrum.

T-Mobile also closed on its agreement to purchase the remaining interest of Iowa Wireless from Aureon on January 2. This agreement enables T-Mobile to further broaden its LTE footprint in Iowa and western Illinois and will eventually give Iowa Wireless customers access to Un-carrier benefits and America’s Best Unlimited Network.
