can somebody please tell me what a 'WiFi' minute is?

Answer 1

Can't say that I've ever heard that term. Where did you see it?

Answer 2

very strange term indeed. I'm gonna take a few wild guesses here:

1. A break (as in a coffee break) where u go log on to a wireless internet network to check ur email or some other quick task.

2. U are using somebody else's wireless network, and they count the minutes to charge u afterwards.
