Signal mostly oscillates from 0 to 3. Reception is appalling. Have to walk around the house to even get a signal that allows us to call out. Once the signal drops to 1 or 2 the communication become garbled to the point that you can no longer understand. We are so out of AT&T the minute we can get out without penalties.

Low to no reception inside house-- one bar outside. Frequently lose calls (rarely can complete them) signal is poor at best. Phone never rings, voicemail is delivered when leaving the area. AT&T is trying to put a new cell tower in our area, and some of the local NIMBYs are actually fighting it. At least AT&T is trying to fix this service hole that has been here for at least 5 years.

I called AT&T since the reception is pretty poor. The technician said that this area is in between a couple of cells coverage areas. So if you live in this area, I would not recommend AT&T.

Signal is getting poorer on our complex, looks like AT&T is slacking much more... wake up AT&T, when Verizon gets their hand on the iPhone, I'm moving over the fence.

Reception and call quality has been typically poor the last two years for both the BB Bolds we have. Today July 28th, 2010 was specially bad, hardly any 3G signal the entire day, mostly GPRS and Edge.

I only get reception in one room of my house, and usually have to stand next to the window to avoid dropped calls, echo, and other problems. AT&T coverage around the silicon valley area seems terrible in general, particularly in the 3G band. I frequently receive voice mail for calls that never rang my phone, it sometimes takes 30 seconds or more to connect a call, and the call audio quality is absolutely terrible. I have to ask people to repeat themselves all the time due to audio drop outs or noise. Despite the terrible service, AT&T is overpriced when compared with other carriers. I love my iPhone, but have grown to loathe AT&T.

Regularly get voice mails 4 days later, missed calls that never show up on the phone. For example today I woke up to my phone having six frantic voice mails from my work, each one made after 3pm yesterday, between 3pm and 5pm. All of them came through sometime between 2am and 5:30am in the morning. I was out of the house around 8pm so it's not my reception. It's ATT. The techs tell me I have wonderful service and need new phones. Bull! Both phones had this happening over 2 years ago when they were brand new. Contract is up in October. ATT has horrible customer service. They will never let you out of your contract no matter how bad your service really is. Beware of signing with them.

AT&T have worked flawlessly for the past 3+ years. Anywhere, inside outside etc. 3yrs back had T-mobile, had no coverage, had to break contract coz of that. But a lot depends on phone too. I now have two Samsung phone and I don't get any signal at home (unless the phone is perched up on top of a window sill, in the tallest tower in the highest room!)

Pathetic reception outside and inside the house. If I'm lucky I'll get 2 bars. Most of the time calls go to voicemail directly.
