I've tried looking for the answer to this question both here and Telecom's site.
Telecom says that if you get the prepaid broadband for $29.95, you can top up online and it gives you the link to do that. So to renew it each month costs $30, but they only have top up options of $10, $20, $40 and $60.
So assuming you start at $0 and don't go over the allowance, does this mean that for example one month you'll have to pay $40 (leaving you with $22 after the $12 bonus top up minus the $30 for the broadband), then next month pay $10 to be left with $2 once the broadband is paid for, then back to $40 again in the third month and so on?
Is it possible to top up $30 through other methods?
Also, when you top up when does the countdown to the end of the month begin, as soon as you top up or as soon as you start using it?
