Are you on an older Bill Pay plan, either on your phone or broadband? Have you recently changed your plan or are you thinking of upgrading to one of our newest plans Three Essentials 5G or Three Freedom 5G? If so, here's what you need to know about what to expect on your first bill after you change.
There are two ways that our legacy plans were billed:
- In advance
- In arrears
- If your old plan was billed in advance, nothing will change on your next bill, and your new plan will continue to be billed the same way. Billed in advance simply means that you pay for your plan before you use it.
- If your old plan was billed in arrears, this means you paid for your plan after you used it. Your first bill may seem higher than you were expecting. This is because you will be charged for your first month’s line rental on your new plan in advance and the cost of your old plan, up until the date you moved onto your new plan. This is reflected on your bill as ‘Total Monthly Charges’.
If you have changed your plan in the middle of your billing cycle, this will also mean your bill may be higher than expected.
Plan changed Mid Cycle: Arrears to Advance Billing
Let’s say your billing period starts on the 27th of the month and you changed plan on the 13th.
This means that you will be charged in advance for your new plan. You are also charged for the days used on your new plan. So, you are charged for using the plan from the 13th until the 27th, when your billing cycle starts again. As your old plan was billed in arrears, you are also charged for the days used on the old plan. These all appear on your bill in “Total Monthly Charges”.

Plan changed Mid Cycle: Advance Billing
So, you have changed bill mid-cycle, but your new and old plan both are paid before you use it (billed in advance)
Again, let’s say your billing period starts on the 9th of the month and your plan was changed on the 2nd. This means that is there is a charge on your bill for your new price plan. You are also charged for using the old plan from the 9th until the 2nd, when your billing cycle starts again. As your old plan was billed in advance, you will see a monthly service credit for €X on your next bill. This credit is given to you for the days not used on your old plan. The below image is what you will see... (Please note that the plan name might be different.)
