I don't think you have a accurate usage model for this product.
The point is not to make a call while you are mobile, it is to
*receive* calls while you are mobile.

There may be payphones handy while I am out, but how is anyone
going to reach me without a cellular phone?

I would also say a substantial number of calls are aimed at a
specific person. Many business calls may be "office" oriented
(although business again has a need to access mobile personnel)
but almost all personal calls are person specific.

Note that there are a large number of businesses where the
personnel are mobile as much as possible like field service,
sales, building contractors, etc.
