AT&T does not work unless you are on Hwy. 1. At 1, you can only get 1 bar of coverage. Tomorrow, I am going with Verizon. AT&T provides absolutely ridiculous service.

Very poor reception. Under 80kbps and dropped signals. Unbelievable in 2018 in such an urban / tech savvy area.

10 years ago, it was far better, now I have to stand in the street to find a good spot to have a call without it dropping. I'm waiting for the first carrier to improve the coverage and then I will switch.

Full bar but working with edge all the time. Connection speed varying from 0 to 200 kbps. I paid for unlimited data (4g) and it is really annoying. Even in the city center it is not great, even though it goes around 4 Mbps in that part of the city.

My wife and I used to get good reception a year ago, now we can't even get an app to work. We get calls most of the time but if we move around the house while on the call it gets choppy.

Learned that Verizon and AT&T vie for cell tower locations. One would think that in the midst of Silicon Valley someone would be able to negotiate functional reception for subscribers. Expensive booster(s) are useless. Calls continually 'drop' and / or have abysmal reception.

1 Out of 5 (1 star) | 5guys Burger , a Few Doors Down From the ATT Store, South San Francisco, CA 94080 |

I'm sending this review from inside the 5 guys restaurant in westborugh square shopping area, right by the ATT store.! Reception for AT&T in this area is very poor. Inside our house which is up the street off rowntree way is spotty at best. We're paying all this ridiculous amount of $$$$ on AT&T wireless and U-verse and they still can't fix the problem in this area. I remember telling one of the AT&T reps at the store about it a few years ago and all he can say was "we know, we know.."jeebuz..!

Used to have service with Cingular; worked fine. When they were bought out by AT&T service was spotty at best. Since April 2016, I have had NO reception at all. Called AT&T for a refund, DENIED. Asked for a mini-tower, DENIED. I will try T-Mobile next, Verizon after that.

No signal for 2 weeks and A&TT service claims that they will need a month to fix the problem. I reported the problem Oct 2 2017
