I only get one bar at my office here. It's worse since the condos went up across the street.

2 Out of 5 (2 stars) | Seaport Dr. | Penobscot, Redwood City, CA 94063 |

Very limited reception, in most buildings in RWC there is at best 2 but mostly 1 bar. Many dropped calls and very very slow data connection

Verizon's service is horrible to non-existent at Stanford. Occasionally, I will get 1-2 bars of 3G, but most of the time it's 1X. And sometimes even when it's on 3G, the phone just sits there and spins when its trying to load anything from the internet. It's hard to believe it's 2015 when you can't even get service in one of the most populated areas of the country from the biggest carrier.

You would think that a cell service would pick up better the top of a hill. In fact, the hayward hills have horrible service. T Mobile should get this taken care of.

I get great coverage in Pacifica. Home is the manor district. Hikes in the parks, mori point etc. No coverage at Nicks! I'd like to switch to Sprint because it's much cheaper but there are no recent reviews. Please help!

Frequent dropped calls, poor reception. I'm home and a lot of the time I have zero bars. Unlimited internet is a joke, can't even use it. Can browse the Internet and check emails ok, but streaming videos rarely works; Netflix works sometimes when I turn airplane mode on and off.

1 Out of 5 (1 star) | DALY CITY SPRINT STORE SERRAMONT AREA, San Francisco, CA 94112 |

Went there to buy phone,and these jerks added a home phone service on my plan,i tried to return phone and they charged me 35$ restocking fee plus 35$ fee on the hm phone service..well these jerks told me that the refund that was suppose to be returned to me on my card cannot be accepted for restock fee,so I had to pay out of pocket,and with all said and dont I could not even return the phone.anyone who goes with Sprint better rethink there network sucks,there are alot better ones out there.ALSO TO ADD<<<< THERE CUSTOMER SERVICE FROM A SCALE OF 0 TO 10 I WOULD RATE THEM A 0 BECAUSE CUSTOMERS ALWAYS COMES FIRST NOT THEM.

I've had AT&T for 15 years without issues until last year. Dropped calls and no reception at home. Have been dealing with AT&T for several months without resolution. Received micro cell free of charge. Continue with poor service. Will be switching carriers soon. There CS I poor. Will not provide credit ether.

The cellular reception I receive in my area is okay. Sometimes I have 5 bars, sometimes I have 1. But I always have at least one. Everywhere in my house there is some sort of signal. Don't know why some people said they had bad connection.
