New York Gov. Andrew Cuomo has made it a priority to revamp the archaic NYC subway infrastructure. Part of his plan for "embracing the digital future" includes adding Wi-Fi service to all 277 underground stations by the end of 2016 and cellular service in 2017. This is excellent news for the straphangers of the future, but what about today's riders? Turns out that with the right timing, you could make that emergency "I'm running late" call—but only if you know which of the underground stations have reception.
