AT&T

I have broken multiple iphones in frustration to dropped / ghost calls. Worst ever.

Never receive calls at home. Need to stand close to the busy street with heavy traffic to use the phone, which makes it useless.

I am amazed at how AT&T is still in business. I am stuck to the phone thanks to their expensive contract cancellation fee but I wonder why people sign up for AT&T in the first place. The place where I live has 1 to no bars from AT&T towers and when I call them, they said everything is great! Their solution was to "buy" a microcell which is itself $199. I asked them to give me one for free which they declined. So I was "forced" to buy one. Two more months and I am done with AT&T.

If I go stand at my back window I can have a conversation. Otherwise people can't hear me.

I have been complaining about dropped calls, calls going directly to voicemail for months. They replaced my expensive phone once. Nothing changed. I get 0-3 bars standing outside my house. Signal jumps up and down constantly. Currently they are checking the towers but I have doubts they are doing anything. Before I switch carriers I will probably invest $300 in a cell signal repeater / amp that "might" improve the signal inside the small house. If I have to swich, Verizon seems to be the carrier of choice around here.

No 3G. Between 0 and 3 bars (out of 4) on 2G. Outbound calls fail or are very noisy and crackly.

reception is only good to make a call but you have to find a good spot indoors, if you go outside you might get 2 bars... .

I live right between Intel and Apple, and I get better reception in Mozambique or Uganda or Kenya!

In Tasman building addresses 3001, 3003, or 3005, my ATT coverage typically shows only 1-2 bars. I'm frequently unable to access the internet, and occasionally drop calls in these locations as well.

The reception is poor. Most of the time I can't hear clearly what the person on the other side is talking about. I get call failed occasionally or just the call just canceled automatically. My phone is showing 5 bars most of the time but would drop to 3 or no bars during call. I do get drop calls occasionally.
