I can tell you my mom and sisters' experience with Cingular. They had them for 4 years when it was known as Cellular One. All of their problems started under the Cingular name. Customer Service always turned off their service, even after paying the bill on time at a Cingular Wireless owned store. My mom and sister wereon the phone every month trying to get their service turned back on. Cingular treated long time customer like this this that they eventually decided to the $300 early termination fee ($150 per phone) to try someone else. Cingular hadn't coverted to GSM at that time and rollover wasn't offered yet. While the offer is nice, and they offer nights and weekends starting at 7pm, and unlimited mobile to mobile, Most people I talk to in my area complain the most about customer service. Signal strength is fine. Another problem I found out from a Cingular customer that might be plaguing Cingular customers in markets where AT&T have towers at. Unless you have nationwide service to where you can use your mobile to mobile minutes, this guy who picked up a shipment where I work couldn't use his mobile to mobile minutes because AT&T towers kept picking up his calls in Cingular's coverage area. I could understand if he were in AT&T's area that Cingular doesn't cover, but in an area that both services overlap, AT&T shouldn't pickup the Cingular call. That should be resolved when the services merge toward the end of the year. But Cingular needs to improve their customer service if they expect to keep the large customer service they're going to acquire. My one friend on AT&T already has plans to drop AT&T before the merger is complete since he doesn't want to be on Cingular Wireless, simply because of the customer service problems. That's why I think if it doesn't improve, Verizon Wireless will likely acquire a lot of those customers since Verizon Wireless has a low turnover in customers because of customer service satisfaction, better coverage, and usually fewer dropped calls (unless you own a Motorola, then you'll get lots of dropped calls). Cingular has lots of perks, but most people I know don't like customer service, but usually don't have problems with coverage though, at least in NW Indiana and in Chicago. Verizon Wireless has fewer perks, but that's because they're a premium service, but Verizon Wireless has spent lots of money building their network in new areas, as well as fixing coverage issues in existing areas, whether from a previous merger, or from where there are more users than circuits to handle the calls. It's nice that Verizon Wireless made mobile to mobile unlimited, but the IN-Networking name needs to go. At least from my experience, Verizon Wireless covers their areas well, both in northern Indiana around South Bend, Michigan City, Valparaiso, Gary, and in the Chicago metropolitan area, and up in Milwaukee. Verizon's roaming partners are another story, especially Alltel in Michigan, where portions of their network is still analog, though Alltel did add more digital coverage, but cover I-94 so poorly. That's where you need to get a tri-mode phone with them since it's Verizon's roaming partners that haven't completely made the transition to digital like Verizon has.
