AT&T Investments Connect Communities

In Maryland, we invested more than $700 million in our wireless and wireline networks from 2019-2021.

Cities and communities throughout Maryland are impacted by this investment, including nearly $500 million in the Greater Baltimore area.

We know how important it is for our customers to stay connected. That’s why we’re focused on boosting network reliability and capacity as we expand our network nationwide. This helps residents get the best possible experience over the AT&T network where they live, work and play, as well as supporting first responders on FirstNet®.

Committed to expanding connectivity, our investment focuses on all network layers—from 5G to FirstNet.

  • Unlocking the Power of 5G: AT&T is America’s Most Reliable 5G Network1. AT&T currently offers different flavors of 5G*, which helps enable the network to reach its full potential.
    • AT&T 5G using low-band spectrum offers fast speeds and reaches more than 277 million people in more than 18,000 cities and towns in the U.S. including communities in Maryland.
