Just got my 64GB 5S in Grey/Black
So far this thing kicks the pants off of VZ. I'm in the Boston area, typically a stronghold for VZ coverage, have never had any other carrier than VZ...going back to 1998. I can tell you that the north shore of Boston in particular, where VZ barely gets you 3 bars of LTE in places and often switches to 3G, T-Mobile is lit up 4 bars of 4G and sometimes 3 bars...even in my building, which is full of steel and reinforced walls where VZ drops my calls on a daily basis, T-Mobile has no such problems at all! I am streaming from Netflix over 4G (3 bars) while sitting in my office where again, VZ can't even keep a phone call active. I can tell you what I'm thinking, just 12 hours into my 'test drive'....
This is insane, I'm paying about 130 bucks/month for unlimited data/calls/texts with VZ (grandfathered into the unlimited data plan from the first time VZ got iPhone). I may have to make the move when the 6 comes out.
