It's a bit pricey at 50 per month and byte charges over some GB but yes its faster than dialup.
Ask your Cellular company for details.
I have a home computer (not laptop) running Windows XP home Ed. I have At&t dial-up and unable to get cable or DSL where I live. Satellite is too expensive. Can I use a USB Broadband connection on my home Computer, which will increase my Internet speed? How does this work? Will I need a separate modem?..
