Cingular, $40 a month, no roaming, free LD, etc. I don't use it all that much so I signed up for 400 rollover minutes. I now have about 1,000 minutes rolled over, so they will be free. Phone was free too.
Lots of times if you go thru your local phone company you can get a good deal but make sure you ask about ALL the plans with lots of companies before deciding. Like the saying goes,"Let The Buyer Beware".
DE, my eldest lives in Pasadena, travels a lot, uses AT&T wireless and it's fine there in that area. Right now she is in AZ, called today, and everything was great.
