My E train was stopped for a while at 14th St. last Friday and lo and behold, I received a text from a friend! And what's more, I was able to text him back and tell him I was running a bit late! And... the signal was actually really strong.
Little did I know that 14th St. is the first subway station in the city to have cell phone service. The City is gradually rolling it out to more and more stations... It's about time!
