Almost always great.

Reception and transmission both lousy from my new home in Denver Highlands area. This contrasts with the excellent Verizon service everywhere in Boulder.

Even with my old Cingular phone I had no reception problems. Great reception around here. If you cross under / into the TREX construction, the reception gets iffy.

Perfect reception throughout the metro area with my Sprint service. No issues with it any where. Great functionable service!

I drop calls constantly in my home. My family is starting to think I just don't like talking to them. Going outside sometimes works, and sometimes it doesn't. For fun I can watch the little bars do a dance as I walk around my living room, or even stand perfectly still. I will either need to get a land line or look for a better provider soon.

No reception inside the building in a major city building in the middle of downtown.

0-1 bars, 2 very occasionally for a few seconds. Complained to T-Mobile multiple times, they always say "we see excellent reception in that area" which isn't even true in the street, the yard or the house.

I get fabulous service with Sprint throughout the metro area - I even used to get several bars in my basement office, although that hasn't been so good in the past couple of months. The problem with Sprint is how quickly you lose service once you get outside the metro area (or really, any metro area - I got no reception almost the entire way across Nebraska, for example.)

From inside buildings. Seriously annoying!

Absolutely no problems with reception. 4 Bars solid inside home; Main Floor
