I have two GSM cell phones that I tried on the T-Mobile network and one gets terrible service everywhere around here (4G LTE, but only bands 2, 4, and 17 because it was an AT&T unlock) and the other gets fine service everywhere. Sprint is good too, but inside buildings (especially Gropius) actual cell service is pretty bad. It sounds nitpicky to be complaining about LTE bands, but to get the most out of T-Mobile you really need a phone that handles LTE band 12.
Could you elaborate on this? T-mobile looks to be by far the best plan for me but I'm worried about not getting reception in Gropius. According to this http://www.apple.com/iphone/LTE/ if I have an IPhone 6S I should be good to go on T-Mobile?
