It is so frustrating to have to go outside to make a phone call. Switched to Verizon when they were the only ones that worked on the metro. Sprint worked better in my home.

Sprint's coverage is horrible. I drop calls, data is slow, and I cant' hear anyone! This phone is going back and I am getting Verizon. I heard they are great here. Coming from AT&T, I will be VERY happy!

AT&T is lucky they had the iphone for so long. I am switching the first chance I can to either Sprint or Verizon. Never thought I would change, but 3G service is so unreliable that it has become a liability to have my phone due to dropped calls and no calls coming in. Terrible, do not get AT&T if you are looking for new service

On the 4th floor of a newer bldg, home to big law firm and many wealthy people reside on upper floors. The ONLY place I can get a consistent signal is next to a wall of glass at the outside edge of the building. Of course, I work about 30-40 feet away from that wall, so I get virtually no signal all day. I know, I know, the building needs to install repeaters or passive antennas to bring the signal in. But I never had that problem with my Verizon phone in 2007-2008, except when I worked in the basement of a building.

I work on the 7th floor on 12th st. in downtown DC and I get no bars. My Blackberry doesn't even pull my email. I have never had this happen anywhere else in DC with Verizon, but if I can't even get my email in an office building two blocks off Pennsylvania avenue, that's a problem.

Whenever I come out of the South Exit of the Dupont Circle Metro Station and keep doing down 19th St, I get no reception at all from T Mobile.

No reception inside office building. BUT! Just switch to roaming only (free!), which accesses Verizon. Full bars. No problemo.

No reception inside work building (roams all day and wears out battery). Also no reception in L'Enfant Plaza unless go into atrium area with skylight above. Great service outside building and in outside downtown DC.

I can get NO reception in any metro station under ground.

Awful Sprint reception. Sprint roams for free, but at this location there's half a bar of reception, meaning that the phone doesn't transition to roam and the calls won't go through either...
