help the computer illiterate...cell phone as modem?

[Skipbidder]

Hello.
I'm old and don't understand how these newfangled computer things work.
It's end-of-cellphone-contract-time.
One of my new phone options includes being able to use the phone as a modem.
Can I play poker this way via laptop?
Are there security issues?
Help a n00b out.
(Yes I did try to search for this and didn't find anything...although I likely screwed that up too.)
