I'm currently on the 40GB per month plan, and wish to upgrade to 60GB a month. I'm just wondering, when is the best time to do so? If I did it a day before the 40gb reset, would I be charged for both the 40gb and the 60gb? Or if I did it after the 40gb reset, would I still be able to use the 40 gigs I was charged for, or would it instantly change over to the 60gb plan? I hope this isn't too foolish a question, but I was unable to find out on the Telstraclear website.
Cheers.
