1 Out of 5 (1 star) | Hwy. 1 | 92, Half Moon Bay, CA 94019 |

I live 1 mi N of Half Moon Bay and the ATT service has dropped to barely manageable to mostly nonexistent. In the backyard, signal is -105 dB. Missed important calls and receive texts 45 min late.

ATT is very non supportive for cell phone reception problems. Can't even get a service tek to come and assess the problem. Very bad

I have constantly 1 to 2 bars at my home with what supposedly says lte coverage. Drops calls frequently and 1mbps download. We live in huge tech community for Verizon to not do anything about this. Complete bs.

Constant 3 bars of "LTE" displayed on phone, speedtest barely breaches 2.5 mbps, streaming 240p youtube video during off peak times and getting the video 5 seconds at a time before buffering is needed. Inside / outside doesn't matter. Call quality is terrible and I catch about every 3rd word of the conversation because the signal cuts out, sometimes I get missed calls when my phone didn't even ring. Fix this T-mobile, I switched because I was getting shafted on prices by verizon, now I'm not getting shafted on prices but I sure am getting shafted on data coverage.

No service when you enter the center of town. Probably some misguided not in my backyard thing regarding cell towers. Twenty words is a silly requirement to say "cell service doesn't work here".

Service has been spotty here in Redwood City (never more than two bars, usually just one) since I arrived on Saturday evening 4 / 22 / 17. Now (4 / 24, 9:30 a.m.) there is barely half a bar, alternating with no bars at all. I just got a "missed call" message without the phone ever ringing.

Been with Sprint for over a year now and the service is so poor that I often want to get a hammer and just pound on my phone out of pure frustration and Sprint denies that I even have a problem even though I want to provide video proof how bad the service is they keep lying to me saying that there's no problem, it takes hours and hours and hours just for them to tell you that they understand but there's nothing we can do about it. but you will still get charge the full bill even though they're not providing the full service
