If you’ve been encountering cell phone signal issues in the New York City subways, a solution might be on the way as Transit Wireless has reached deals with AT&T and T-Mobile to provide cell phone access at subway stations. Both carriers have snagged a 10-year agreement to link their phones to Transit Wireless’ network in a deal that will eventually reach all 277 terminals in the city. Both carriers have the option of renewing the deal in five-year blocks for four times. Perhaps such a move will help AT&T and T-Mobile get one over its rivals Verizon and Sprint, since they will lack an official way of getting cellular coverage below ground.
