4 Out of 5 (4 stars) | CERAS, Stanford, CA 94305 |

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!

Really terrible service in this area, might find one bar in a few spots. Even worse the bad network confuses this phone which keeps switching into restricted mode requiring a power off to reset.

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.

I get good reception where I live in downtown Palo Alto area. Reception on Stanford campus is terrible, however. Slightly better reception on med school campus, but still pretty darn bad.
