When I first joined, I called customer service about roaming. They informed me that if my phone said "ROAM", then I was roaming, otherwise I was not.Recently I had large roaming charges, although my phone never said "ROAM". Cingular refused to remove any of the charges for the following reason (in an email):"We see that all the charges applied to your account are valid charges. The actual rates charged will be determined by the information contained in our billing system, not based on the phone's display. Hence, we would not be able to apply any credits against the roaming charges. "We went back and forth several times, but Cingular stuck by their reasoning. All they did was thank me for my loyalty and wrote a half page marketing blurb about how they are a top service provider and how I can upgrade my phone and service. Unbelievable.Do not go with Cingular. In the event you love them or one of the phones they offer, then first ask yourself several questions.1. How will you exactly know when you are roaming?2. How will you know if information provided by Cingular is accurate?3. Do you want to buy Cingular phones that Cingular will not stand by?4. Are you ready to understand billing software and systems?5. Are you ready to deal with a company who can't take responsibility for products, services and information it provides?Don't waste your time with Cingular.
