I've had Cingular, and its prior CellularOne since 1996 and had no problems but, it works for me as a single plan with a certain amount of minutes included, etc etc. I dont have rollover but, could upgrade to that, lots of gotchas there. I have black holes as well, but it seems most of this citys coverage does so, I dont think Id be getting anything better to change it.
You've really gotta do your homework with cellular plans. You have to go over all the available in the area, what you get, what you dont get, what the carges will be if such and such, etc etc.
This is one of those you better take a while figuring it out or itll burn ya in the end.
To consider--the phone you get is this going to be garbage within a year? How much does an upgraded phone cost/how much can you get a better phone for now when you sign up?
Can you get a one year contract with no hidden items like early termination, termination due to late payment, termination due to other reasons, does this type of thing lead to hidden costs of early termination?
Billing-Prepaid or not? Deposit or not? Itemized billing?
Local calling area, Long Distance calling area....get this spelled out in detail. If there is an area you frequesnt, ask if that is local or local roaming? Is local roaming added fee? Is long distance roaming additional?
Anyone who sells these plans gets about 50-80 bucks a sale so, yeah...make mr minimum wage at the Kiosk give you full details...its worth it for him--dont let him/her fool ya.
Look for extras but, dont let that be a deciding factor. Rollover, nights/weekends, long distance, phone included.
Good Luck
