I want to report a dead zone in the commercial center of Concord, MA. The phone registers a strong LTE signal, but any attempt to use data fails with no connection. This has been a persistent problem for about a year. This has been a problem across multiple phones. I hear others on the train platform complain as well.
This is one of the most central business districts in town. The train station at 80 Thoreau and the grocery store at 211 Sudbury are public places in this area, along with multiple restaurants and coffee shops. The zone has at least a 1/2 mile radius.
(I should also note that connectivity on the train line between Concord and Boston is also very spotty, but that is another issue.)
