I no longer have access to that number but cannot change / update to my new number as when I try the required security code is automatically sent to the old but registered number - any ideas I am sure it's an easy fix <span class="lia-unicode-emoji" title=":thumbs_up:">👍</span><span class="lia-unicode-emoji" title=":thumbs_up:">👍</span></P> Sat, 15 Aug 2020 07:50:36 GMT https://community.o2.co.uk/t5/My-O2/Registered-number-used-for-security-checks/m-p/1381620#M9270 makepeace1975 2020-08-15T07:50:36Z Re: Registered number used for security checks https://community.o2.co.uk/t5/My-O2/Registered-number-used-for-security-checks/m-p/1381621#M9271 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/4108730">@makepeace1975</a>&nbsp;</P><P>I guess the only way is to call customer service <LI-PRODUCT title="Guide: Coronavirus Community Help and Support" id="Guide069"></LI-PRODUCT>&nbsp;</P> Sat, 15 Aug 2020 08:04:34 GMT https://community.o2.co.uk/t5/My-O2/Registered-number-used-for-security-checks/m-p/1381621#M9271 MI5 2020-08-15T08:04:34Z Re: Registered number used for security checks https://community.o2.co.uk/t5/My-O2/Registered-number-used-for-security-checks/m-p/1384162#M9406 <P>Hey there&nbsp;<a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/4108730">@makepeace1975</a>&nbsp;, hope you got everything sorted ok with customer service after you last posted about your account.
