This is a #dcfilter question - for people in/around DC. How is T-Mobile? I'm seriously thinking about switching on over from AT&T - I've been experiencing a lot of dropped connections, slowness, sluggishness, etc. with AT&T on my 6s. I understand T-Mobile got an improved band for TMO, so can anyone who has TMO and is in the DC area (and preferably, recently switched), say if TMO is better/good in the DC area? Thanks!
