Nice. All of those stops should be LTE but it takes longer at some stops than others for the phone to pick it up.Riding the 1 train I was able to listen to pandora from 147st to 14st nonstop.
These are the signals I was getting while riding the train.
14th 4G
18th LTE
23rd LTE
28th LTE
34th NS
42nd LTE
50th LTE
59th E
66th LTE
72nd LTE
79th 4G
86th 4G
96th LTE
At 7 Ave and 59th street on the D train my phone jumps right on LTE. At Rockefeller Center I get 4G then it takes up to 3-5 minutes for my phone to switch to LTE. Very strange.
