Poor reception and often no reception at all. When a call is actually recieved it will often cut out in midsentence.

HORRIBLE. Technical support has been abysmal. This company is awful to work with. They're crooks.

About 2 bars in the plane when taxiing and 1 bar in the terminal, with reception cutting in and out. How can AT&T claim global coverage when they cannot provide service at a major airport?

Have had 4 replacement phones because I drop calls consistently. I can't believe a phone can be that crappy so it must be the provider! Yes T-Mobile has great customer service but why in the hell do I end up calling them so much anyways, I'm over it! Thinking about Sprint but all in all Pacifica just has awful reception in parts due to the hills and fog... .I don't think any provider will have perfect service out here. And why is that... i dunno? Every time I look or hike up to the top of these beautiful crests and peaks out here all I find is cell phone towers, so whats the deal?!

In my home usually reception is fine, but sometimes the signal fades away and the quality is very poor or the call disconnected... unreliable...

Reception used to be great, but when the roaming agreement with T-Mobile expired last year, reception became lousy. If I do get a signal in the house, it's very weak. Going outside helps a little, but not a lot. Calls are still garbled. I've called Customer Service twice about this problem. They say it looks like the nearest AT&T tower is 2 miles away. Because of the dramatic shift in service, they're willing to let us out of our contract with no ETF, but we're reluctant to jump ship to another carrier.

AT&T has so many dead spots. Im wondering if its the network or the phone. More bars in more places? lol yea right. I was looking thru the list and I see Sprint has more good comments than any carrier. Just afraid about their customer service. I think reception is more important to me. I will try Sprint.

When I step inside, the signal goes completely out. Outside, up to 2 bars. Friend has ATT and it works fine inside and out.
