AT&Ts, Verizon and Comcast are all set to announce a joint effort Tuesday to crack down on roaming hotspot abuse by roaming wireless providers.

The companies announced a joint “Mobile Hotspot Solutions” initiative on Tuesday, in which they’ll work together to identify hotspot operators and fix their roaming problems.

It’s a step in the right direction from a company that once made headlines when it tried to sue Verizon over a lack of network capacity in the United States.

Verizon sued AT&ts for $75 million in March, claiming it lacked the capacity to handle the growing number of calls it received from mobile hotspots.AT&Ts is partnering with AT&M Mobility, T-mobile and Verizon to identify the hotspots and fix them, according to a statement from the companies.

“The partnership is a great example of the power of innovation in the mobile industry,” AT&t Chief Executive Officer John Legere said in a statement.

“We are pleased to be working with our customers to help them stay connected and connected to their wireless network, while at the same time ensuring they have the flexibility and choice they need to get where they need it.

This will help us meet the needs of consumers in our most important market.”

The plan is part of an AT&s effort to boost the mobile Internet of Things (IoT) market and improve its reach into the home, which was once dominated by cable and satellite companies.

In the U.S., the wireless market has grown at an annual rate of more than 10 percent over the last five years, according the research firm Gartner.
