Each time it says the request cannot be completed and if I have this problem repeatedly I should use a different card. I don't want to use a credit card and this debit card has been activated and is accepted elsewhere. My £10 rolling plan renews on the 11th of each month and I am concerned it will stop working if I can't register the new card. What am I doing wrong?</P> Mon, 02 Jun 2025 15:49:22 GMT https://community.o2.co.uk/t5/Tech-Support/update-card-details/m-p/1796268#M56946 LynneRR 2025-06-02T15:49:22Z https://community.o2.co.uk/t5/Tech-Support/update-card-details/m-p/1796275#M56947 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/5811744">@LynneRR</a>&nbsp;</P><P class="">You can get in touch with Payment Management team on 0800 902 0217</P><P class="">Payment Management opening hours:</P><P class="">Monday to Friday – 8am to 8pm</P><P class="">Saturday – 8am to 6pm</P><P class="">Sunday – 9am to 6pm</P> Mon, 02 Jun 2025 16:16:23 GMT https://community.o2.co.uk/t5/Tech-Support/update-card-details/m-p/1796275#M56947 MI5 2025-06-02T16:16:23Z
