T-Mobile US and Crown Castle International have signed a 12-year agreement to support the build-out of T-Mobile’s 5G network with increased access to Crown Castle’s towers and small cell locations.

The agreement helps Crown Castle generate long-term tower and small cell revenue growth.

“T-Mobile’s alliance with Crown Castle will fuel acceleration of our network build and provide synergies that we can further invest into that build – all in support of our Un-carrier mission to truly deliver 5G for all,” said Neville Ray, president of Technology at T-Mobile.

“T-Mobile’s significant long-term commitment to utilize our comprehensive infrastructure consisting of towers, small cells and fiber will enable our collective teams to quickly meet future network demands,” Jay Brown, Crown Castle’s chief executive officer, said.

T-Mobile is the leader in 5G with the country’s largest, fastest, and most reliable 5G network, including nationwide Ultra Capacity 5G that delivers blazing-fast speeds to more people than any other provider. For more information on T-Mobile’s network, visit T-Mobile.com/coverage
