T-Mobile has said it expects to pass between 12 million and 15 million more households with its US fiber network by 2030.

The carrier, which has pushed its fiber ambitions hard this year, made the comments during a T-Mobile investor event earlier this week.

In July, T-Mobile announced plans to set up a joint venture (JV) with investment firm KKR to acquire fiber Internet service provider Metronet.

The telco, like its rivals AT&T and Verizon, has seen the growing opportunity that fiber presents away from their more traditional mobile offering.

As part of that move, T-Mobile will scoop up Metronet's broadband infrastructure, its fiber business operations, and existing customers. At the time, T-Mobile noted that the JV would "complement" its existing 5G Home Internet offering, a fixed wireless solution currently being used in more than five million households and businesses nationwide.

It also referred to its fiber push in recent months, which has seen the company acquire Lumos Networks as part of another JV with EQT Infrastructure.

“We think there are synergies with our 5G fixed wireless customer base in markets where we’re launching fiber,” said Mike Katz, T-Mobile president of marketing strategy and products during the event.

Katz said that the company's push to drive fiber across the country will enable the carrier to "compete in other areas outside our core mobile business."

The company also outlined its roadmap for its 5G Broadband business. According to the carrier, it expects to reach 7 to 8 million by 2027, before hitting 12 million customers by 2028.

It's worth noting that back in 2021, T-Mobile set out to hit 7 to 8 million on its FWA (Fixed Wireless Access) network by 2025. The company currently has 5.6 million customers.
