Signal strength at 2 bars on a good day if I stand outside and do not turn or move. Inside 1 bar if I stand at a window in the front or the rear of the building. 2 1 / 2 blocks away on Geary Blvd.I get 5 bars.

We spent a week in SF in January, 2017. The vast majority of time, we were getting 4 or 5 bars for LTE reception. The only exceptions were in Lands End Park and in some small pockets.

In two years, I had maybe 3 dropped calls. LTE connection I suppose sometimes slows, but it's almost never noticeable. This is true on the street, at 18th and Castro, and deep inside the apt building. I'm afraid to switch to any other carrier.

As of December 2016. Sprint coverage within San Francisco and the Peninsula area has becoming measurably worse than the prior year. And even then it was not great, but now is terrible. The number of time I receive no data errors and not connected has rusen to dozens per day. The low rate is no worth the frustration. I am counting down the months to when I can switch without penalty.

Phone calls from house or backyard get dropped after 1 or 2 minutes at the most. This is a single family home in a wide open area.

ATT has the worst coverage in the Sunset. Dropped calls all day!

Terrible reception, most of my calls goes straight to voicemail without the phone ringing or vibrating and as a result I have missed some very important calls.

I call people and they cannot hear me but I can hear them. I can't get over to bars in my own home. Are used to have four or five bars. This is ridiculous. I wish I could switch carriers. This is a total joke. why can't Verizon fix the coverage in the seventh and Lawton / Clarendon Oak Park area. why are we paying for something that we cannot use?
