Will: Hi, welcome to Optus chat, may I start with your name please?
You: G'day. I'm trying to make sense of your web pages.
You: I'm Greg.
You: "The first ever mobile broadband cap".
You: $30 - $240.
You: Is there any explanation of what that means?
Will: Hi Greg.  Yes there is.  Those plans are a bit confusing
You: You can say that again.
Will: The times you use the internet, there is a cost involved.  If
      you use it between 7am and 12 pm, you get charged 8 cents per
      mb.  If you use it between 12 midnight and 7am, it's charged at
      4 cents per mb
You: Mb or MB?
You: It says MB on the page.
You: In any case, if I pay for all data, is the $30 in addition?
You: And what's the $240?
Will: No, the $30 is the cost you pay every month.  If you go over,
      the internet stops
Will: The $240 is how much value you get for paying $30
You: OK, so I pay $30 and get 240/0.08 MB?
Will: How it works out is if you use all the internet during the
      "peak" time, you can get up to 3 gigs of usage
You: Yes, that's what it seems.
You: OK, that's what I wanted to know.
You: You should get your web people to put up an intelligible
     description.
You: Thanks.
Will: Great.  It's a bit to get the head around but once you know, it
      makes sense
You: Without documentation, you can't work it out.
You: The web pages need fixing.
Will: No Problems
Will: Thanks for the feedback, I'll pass that one to the manager
You: One other thing: does an unlocked Telstra modem work?
You: I was looking at the NetComm 3G9WB.
Will: Yes, if it's unlocked it will work
You: Thanks.
