How to get Wireless Access in Homeless Shelter?

Hello. I live in the basement of a homeless shelter. I am not allowed to have a phone line or cable line installed in my room. I'd like very much to have internet access for my desktop. I'm disabled and live in a bad neighborhood, so going out to the library isn't always easy. Can anyone suggest to me how I can get online? I really don't understand wifi, but am wondering how to set up or subscribe to such a service.

Not sure if this info comes in handy, but my cell phone does work in my room. It's a T-mobile pre-paid. My old verizon didn't work in my room. Is it possible to use my cell phone as a modem?

My computer is about 2 years old- e-machine.

Thanks in advance,

JoAnn

It will work on a desktop computer, but you need to add a PCMCIA (also called PC Card) adapter, like this one.

Don't expect Verizon cell phone sales people to know anything about computers.
