since Alltel merged with Verizon my coverage has been drastically worse.

The phone will not ring into the apartment. I understand the cell band is from sprint.

Att service in my area is horrible. Even had to buy their Microcell but that is not compatible with the iPhone 4S yet, they say they are still working on software compatibility issue. I am switching carriers today.

Consistent lack of service anywhere on North Island. Frequent dropped calls. If there is service, chances are it won't be 3G. I suspect the terrible service is due to a lack of cell phone towers and ineptitude by AT&T.

I've been an ATT customer for several years with no coverage issues. For the last yr I have experienced dropped calls or can't even make a call or send texts in the North Park area and in my home in North Park. ATT told us that the attenea on my 3gs phone was not functioning because it is common with the phone after 2 years. So we got 2 NEW iphone 4s 3 weeks ago and STILL are having problems. They said that according to "their" coverage maps we are getting good reception.The rip off is that they are trying to sell us a mircotower for $199 to use in our home! I'd rather pay a $2 convienience fee on line fee at Verizon if it meant that I could use my iphone in my neighborhood.

Terrible

We have a condo at the Electra on the 41st fllor facing NW, over 50% of our calls are dropped.

AT&T has had horrible reception for the four years I have had my iPhone. Switched to Verizon las week and couldn't be happier. If you live / work in Kensington, don't go near AT&T. I love Verizon so far.

I have dropped calls in and outside my house almost daily. I am so fed up with AT&T. I have called countless times and used their app to submit poor reception reports over a hundred time and no response except that they will update when changes are made. It has been over a year with no improvement. There coverage map shows "best" service in this area. What a crock of lies.

I barely had cell service until I got a Working MicroCell. Without the MicroCell I have constant dropped calls and failed data transfers. I bought the MicroCell from AT&T 18 months ago. The first one was a complete failure. They finally exchanged it after wasting my time for 17 weeks at the end of 2010 / beginning of 2011 (multiple service calls over 45 minutes long). I will say they did not seem to mind talking on the phone but nothing improved until I got a replacement MicroCell with a firmware update. Now service is more reliable but range is only about 30 feet. I will switch when my contract ends. Good Luck

Bars range from 1 to 4 in my house whether I move or not. Calls to family on the weekends are ALWAYS dropped. So much for free weekends. I'm going to try to get out of my contract!

I have bad service since July 27 2011, AT&T are unable to help, apple says no problem with the device. AT&T suggested that I survey people around me to see if its just my phone or others are having the same issue. They also recommended that I turn off my wi-fi and only turn it on when I need it. AT&T sucks it is time to change!

AT&T Users here, 5 of 5 bars, perfect signal and excellent call quality overlooking I-15 and Hwy. 56. Trying to find cell site locations because the signal strength is so perfect here (96%)

zero to poor reception

I live at the north end of Westwood, Rancho Bernardo. We've never had a problem here. Great reception. No drops. My cell phone works better than the VOIP phone we have.

I usually have 1 or two bars. The last two days I've had no signal at all and the phone barely picks up the wifi signal from my own house. I'm on my laptop right now where the laptop says 5 bars and the phone shows 1 just for the wifi signal. Weak. False advertising on AT&T's part. They should take down their bill boards claiming to be #1.

We usually see neighbors standing on the sidewalk or in the street talking on cellphones trying to get reception; our phones (AT&T) get no reception in our house or yard, so we must go into street in front of the house; often even then it drops the call. We were advised we could buy a tower from AT&T for $150 to ensure that we would always have "five bars" on our cell phone. This device would be attached to our computer. Great, except in the event of a power outage, and why should we have to pay out-of-pocket anyway?

Have over 5,000 unusable rollover minutes on my iPhone. It just doesn't work at home in Kensington. Horrible service and AT&T doesn't care. They call all the time re U-Verse but I'm terrified to switch to that! Can't wait for iPhone to come out with a Verizon model - it COULDN'T be any worse than AT&T!

Drop calls all day long! Everytime the coast guard has its hellicopter in the air, the calls are dropped! I think the military interferes with cell reception.

AT&T is weak to non-existent in this area. There are 2 dead spots on Mountain View that *guaranteed* you will lose a call. It is bad all along Adams Avenue, including from the entrance ramp to 805 until you get almost past where 805 goes over the 8. (AT&T always says the same thing when we call "oh there is a tower down today in your area". Liars!) Used to have Verizon and they were not a whole lot better. Not sure why this area has such bad coverage!
