Just in case Sprint doesn't offer coverage in your locale, here are some
other U.S. carriers and their list prices for unlimited Internet access
from a PC or Mac:

T-Mobile: $49.99 per month
Verizon Wireless: $59.99 per month (slower 1xRTT service), $79.99 per month
(EV-DO service)
AT&T/Cingular: $59.99 per month with voice plan, $79.99 alone
U.S. Cellular: $60 per month

Verizon, AT&T, and Sprint have the higher speed services right now (on
parts of their networks), but any of these services will be more than
adequate for 3270 connections if that's all you need.  One of my colleagues
demonstrates WebSphere Developer for System z over one of the 3 higher
speed services, and it works quite well.

There are some potential reception advantages to the new USB-connected
cellular wireless modems versus the card-based ones, so that might be a
consideration if you're less concerned about ultimate portability. Plus you
can move the USB-connected modem to any particular machine quite easily, so
if you only need it for demonstrations you can share one (or a smaller
number) among several people, even with desktops.  Another possible option
is to add the data service (above) to your existing mobile telephone, then
buy a USB cable or (in some cases) use a Bluetooth wireless connection
between your laptop and the mobile telephone.  In the case of AT&T you
won't even block incoming voice calls when you're connected that way.
You'll save a buck or two by avoiding the extra line charge, and you won't
have to pay for the modem hardware or sign another contract.  (Most
carriers call this "tethering," and it is considered a feature added to
your existing line and your existing contract if you use the same phone.
Thus, if you're working on a big project involving, say, 3 months of demos,
you can add the feature for 3 months then take it off again.)

Your mileage may vary, but generally this is all how it works.
