I know several people who use the Afghan cell networks, primarily Roshan. I think at least three are using their own personal cell phones, including an iPhone and a Blackberry. I don't remember the rates exactly, but it's reasonable considering the circumstances.

I use Skype to video chat every night on a commercial satellite ISP sponsored here on base by AAFES. I pay $100 a month for the top tier upload and download speed, and I think it's barely adequate to push the video upstream. Again, it's worth it to me.

Good luck, and stay safe.
