Im currently on the telcom pro plan thinking of changing to the big time plan due to the excessive 2c/mb overage,
Is the cost worked out by the number of days you are on the plan? (eg, $51ish dollars for 20days on pro plan) Is it best to use up all your current data cap before switching? does the data cap reset to 0 after the change?
You have basicly got it, as Tcom charges a month in advance, the day you change you would be credited the part month you have paid in advance and BT would be charged part month plus a full month to get you ahead of yourself again. I.e Pro $79.95 per month, 15 days left in your billing cycle would be 79.95 / 31 * 15 = $38.68 as a credit, for BT $59.95 / 31 * 15 = $29.00 as a part month debit then the full $59.95 to the month in advance. Doesnt really matter when you make the change as it would just effect how big or small the part month credits and debits will be.
