IPs on Sprint/Verizon/ATT

Does anyone know how many IP's are rotated from a wireless card? I currently have a sprint card that I use for different things. Any help would be appreciated.

In my experience with that particular card, you get maybe 2-3 local ranges if you're lucky that are all in the same general block. So it's like 1.2.xx.xx and 1.3.xx.xx and maybe 2.2.xx.xx, all in your general geographical area.

Other cards may act differently.

Do you by chance how an estimate of how many numbers are in a local range?

Thanks for your help
