Why is my first bill more than the monthly charge I signed up for?
Your first bill might be a tad higher than your usual monthly plan. That’s because if you join part way through a month, those days may get added on to your first full month’s bill, depending on your billing date. This is called pro-rata. Don’t worry, this is a one-off charge and on all your future bills, you’ll only see your monthly plan plus any extra services you buy.
