If you make a call when you're showing less than 4 or 5 bars, you can plan on it being dropped. As an uneducated customer, I purchased a Cingular Nation plan (GSM phone) only to find out that the coverage map is so limited that it is worthless.

Cingular service on the north side of Wichita is a joke. The digital network doen't cover all of Wichita. Half of the north side of town is on the analog network. Almost impossible to make a phone call in my house becuase the signal is so poor. Had T-Moblie previous, with no issues like this. Have also tested signal from Wichita to Kansas City via the Turnpike, and reception is horrible. Can't stay on the digital side of Cingular, keeps kicking you to the analog network, and the signal strentgh there is practically un-useable.

Used T-Mobile for 3 years. Finally switched to Cingular and never had any dropped calls.
