One Million Illinois Fiber Locations — Built for the Speed of Life Today

Some things we do online may feel small in the moment—helping a child with homework, jumping on a work call, checking in with family, streaming a show at the end of the day. But if your internet is slow or unreliable, those everyday moments can get stressful quickly — or you can miss them completely. Not good.

That’s why I’m excited to share some great news.

AT&T Fiber is now available to more than 1,000,000 customer locations across Illinois. That’s one million more homes and small businesses that can tap into fast, steady internet built for how we live today—lots of devices, lots of video, and lots of people doing different things online at the same time.

Why is this important?

We like to say that fiber is the foundation of modern connectivity – delivering not only blazing fast internet but also enabling next-gen technologies like smart homes. It’s the key to building a brighter, more connected future.

We’re building this network so it can keep up as Illinois families and businesses do more online—without having to compromise on speed or reliability. AT&T Fiber is available in parts of more than 260 cities in our state.

Milestones like this don’t happen overnight. Between 2020 and 2024, AT&T invested nearly $4.8 billion in our network across Illinois—expanding fiber and 5G and bringing faster, more reliable connections to more places.

And we know a great connection only matters if you can count on it—and if it’s affordable.

That’s why our fiber and wireless customers are backed by the AT&T Guarantee. We also offer Access from AT&T, which provides qualifying households low-cost internet options for AT&T Fiber service.

I’m just so proud of what this connectivity means for people and businesses in our state.
AT&T is the nation’s largest fiber internet provider¹—and AT&T Fiber ranks as the best and fastest home internet². With multi-gig speeds and dependable reliability, your home can handle the big stuff—work meetings, school days, gaming nights, and streaming—without everyone fighting for the connection.

At the end of the day, the connectivity we provide is about making life a little easier—so kids can learn, employees can do their jobs, grandparents can video chat, and small businesses can reach customers without worrying about whether the connection will keep up.

We keep investing in Illinois and showing up for the communities we serve. Because when more people can connect, we can move Illinois forward together.
