This sounds like exactly what I want, except I cannot find any reference to a $9 plan. The cheapest thing on their site seems to be $17. Where does the $9 come from?
I don't see the value of an Internet-enabled phone. As I explained, my ISP is a WISP and in any emergency I would just dial 111.
Click the left arrow on screen next to the $17 plan and you'll see the $9 plan.
