I'm really new to this and I've installed Trello on my computer, but I also would like to be able to access it from my cell phone. Do I have to pay for another license?

No, you don't need another licence.
Trello counts the different users of the workspaces, not devices. If you log into it on nine different devices (like I do), but use the same account, you're still just consuming one licence.
