San Francisco, CA — August 4, 2016

What:

The Un-carrier™ today confirmed its Extended Range LTE, or 700 MHz low band spectrum, which now carries T-Mobile’s LTE signals both farther and deeper indoors than before, is now live throughout the Bay Area.

With a crazy fast deployment of a nationwide LTE footprint and coverage that reaches over 311 million Americans, the Bay Area is the latest area to benefit from T-Mobile’s best in-building coverage offering.

Extended Range LTE Coverage

T-Mobile has been furiously rolling out new spectrum that carries the LTE signal twice as far from towers than other types of spectrum, for a massive coverage expansion – plus it’s four times better in buildings than before.

In the past year, T-Mobile has deployed airwaves known as 700 MHz nationwide including cities such as Los Angeles, Seattle, and Denver so you can use your compatible phone to get great 700 MHz coverage while visiting friends and family in those cities.

Extended Range LTE also enhances coverage in other areas already served by our strong 4G LTE network, so T-Mobile LTE customers there can experience better coverage in suburban and rural areas because the signal reaches further and penetrates deeper than before.

So whether you are enjoying a night out along the Embarcadero or spending the day relaxing at Half Moon Bay -- your coverage doesn’t have to be sacrificed.

Customers with 700 MHz-compatible devices can already see the benefits. Check your device compatibility or upgrade through T-Mobile Equipment Installment Plan by visiting http://www.t-mobile.com/cell-phones.lte-band-twelve.html.
