$1.xx Monthly Plan Charge (generally date of activation until next day)

All this put together, will add up to aprox $69 tax in.
Fido uses prorated billing system, so your plan payment is always a month ahead, and your bill would reflect usage from the current period (which is why your first bill is already available). It's kind of hard to understand, but look at your bill when you can, you'll understand what I'm saying better with it in front of you.
