The next stop for underground subway cellphone and Wi-Fi service will be Queens.

The MTA announced yesterday it will add the perk in 40 stations in Queens sometime in 2013, part of a seven-year plan to outfit the entire system.

The only stops currently wired for cellphone and computer access are in Manhattan at stations along 14th Street and the C/E station at 23rd Street on Eighth Avenue.

Only T-Mobile and AT&T users will have cellphone service, but the wireless service is free.

Transit Wireless also plans to add service to 30 more stations in Manhattan in 2013, including Times Square, Rockefeller Center and 59th Street-Columbus Circle.

Officials did not reveal where in Queens would be next to get service.
