Your line rental is invoiced a month in advance, but your calls are invoiced at the end of the month. So for your first bill, 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 O2 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, and line rental for the whole of next month.
If anything’s unclear with your bill, please get in touch. If you have any queries regarding your O2 billing, please call 0800 0646464 to speak to our Customer Care team or email CustomerCare@welcomm.co.uk.
