Cingular coverage is absolutely terrible. I just switched from Nextel with an i730 to Cingular with a RAZR. I went from average coverage in my house and good coverage in the neighborhood to no reception in my house and poor reception in the neighborhood. Walking around the neighborhood yields similar results with a many block radius. Beware.

I hate this Cingular phone and their add about 5 bars, I have cinglular and they are worst, can hear or some time I can not go thru, the call does not go thru from my home. I hardly get more than 2 and I wonder around all in my home close to window or doors.

No bars at: N 42 16 57.17 W 89 00 57.14 N 42 17 40.36 W 89 01 59.31

No recemption within building. On a good day, one bar once you are 100 ft away. located at the bottom of a hill. T-Mobile phones still get reception even within the building.

Inside any building around here (Rosalind Franklin University), you can FORGET about obtaining reception. My phone simply hibernates, as an effort to preserve battery power. Outside, you might manage to get 1 / 6 bars. When I called Verizon, they sent a technician out to investigate. Their conclusion: "you're located on the edge of a KNOWN trouble zone; there's not much we can do for you!" What blew my mind is that they KNOW about the problems in this area Well, there is something I could do--I dropped Verizon and now I am obtaining WONDERFUL reception with Cingular and my quad-band Motorola V551! :)

No reception in my apartment, and one or two bars on the street outside. My reception only returns after walking several blocks away.

Area of international parkway and woodward ave in woodridge with virgin mobile and Sprint use to get good reception for past 2 yrs but now no reception. People with verizon, Nextel I know can make calls.

I tried All The upper end phones Nextel makes and there is NO RECEPTION at that place, In addition all the phones that Nextel makes are the same software or very close, problem with error codes in the middle of the conversation.and mostly when switching between two calls and If you thinking about the I605 bluetooth tecnology to go with the Lexus blue system. Think twice

t-mobile in and around the lake sucks

My cell phone always cuts out when my Metra train goes under McCormick place. I also lose it going underground into Randolph St. Station. The loss is not gradual as the train goes under. It simply shuts down. I have no idea if non-cingular phones also cut out.
