Understanding your first bill

View your bills and payments, and analyse your spend, with MyO2 Business.

Download, analyse, and email your invoices and itemised data.

If your first bill isn't quite what you expected, don't worry. It includes line rental for the days you've been with us so far. Plus next month's line rental in advance.

Say you joined us on the twentieth of the month. Your first bill will cover line rental from the twentieth to the end of the month. Plus any calls you've made or data you've used in that time. Along with line rental for the whole of next month.

This is a one-off. It'll settle down next month. But if anything's unclear, get in touch.
