Cell phone service and free Wi-Fi have arrived at another 30 New York City subway stations.

The Metropolitan Transportation Authority announced the expansion Thursday of a program that started with six stations in 2011.

Busy Manhattan stations including Times Square, Columbus Circle and Rockefeller Center are now wired.

Officials say all the system’s underground stations will be wired in the next four years.

While cell phones may be used in the stations, there are no plans for service on the moving trains.

The cost of the project is an estimated $200 million, covered by the carriers.
