When you change your plan or upgrade, your bill might look a little different. Here’s why:
How is my bill calculated after I change plan or upgrade?
As with most networks, we bill your monthly line rental in advance. If you change your plan or upgrade, you’ll have paid for a whole month on your old plan, but only used it for part of the month. The cost for both your old and new plan is calculated on a pro-rata basis (so you’ll only pay for the days you used each plan).
You’ll keep the total allowances (like data, minutes, and texts) from your old plan and also get the pro-rated allowances from your new plan starting immediately.
Example.

Let’s say your billing month runs from the 18th of October and ends on the 17th of November. On the 31st October, you decide to change your plan or upgrade.
- We’ll bill you for the number of days (18th October to 31st October) on your current plan.
- We’ll credit you for the number of unused days (31st October to 17th November) on your old plan.
- We’ll charge you for the number of days on your new plan and your next month in advance (31st October to 17th December).
Any out of plan charges will also show on your bill. This could mean the bill following your upgrade might be a little higher than usual.
