Every once in awhile I get good reception, but it is inconsistent. I often have to go outside to get a call. I often get the ringing and will answer, but the other person cannot hear me, or gets every other word. It's tough living in the back of a valley for cell phone users.

Although Verizon has recently revised their website coverage map to show no dead spots in SE Pacifica (back of the valley) that is pure BS. Their coverage has NOT improved and I STILL have "No Service" at my house (and that's when I'm standing outside in my driveway, NOT inside the home). Verizon's cell towers are all located "over the hill" someplace in San Bruno and their coverage for those of us in the "shadows" of the hills in Pacifica is extremely limited. My phone only works at the top of hills (like Fassler) or when I'm on Linda Mar Blvd.or Hwy. 1. If you want service "back in the valley," find a carrier other than Verizon... their coverage sucks here.

Great reception everywhere I have went so far. Even when the phone shows one bar, the quality is great, and even at zero bars, EVDO holds up. Quite surprised. Works well in arillaga gym, basement of CERAS, and everywhere in EV and Governor's Corner as far as my experience. Have not tested in lower levels of Green yet. With roaming (free on many plans) verizons network is available if needed. Very useful!

Zero bars inside my house, no connection. If I walk out to the street, I get 2-3 bars.

Calls are practically impossible inside, and there's a lot of interference making calls outside.

I have to stand by window to get 1-2 bars. Otherwise, no reception in apartment. I appreciate T-Mobile's signal strength map on their site and it helps to know where I can make calls.
