Your MyO2 will give you the last few months in the tariff details section.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues. Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
Depends which billing system you are on. For me if I click on the circle for data in my O2 I can scroll down to "Data Previous Usage" Opening that and scolling to the bottom shows a graph of the past 6 months and a summary of average data usage
This is not O2 and we are all customers here similar to yourself and cannot answer account type queries.
