She uses one of those big buttoned 'thick' phones for oldies. She (thankfully) has no access to the internet. I handle all her online accounts for her.</P><P>&nbsp;</P><P>I've now moved my number to a new provider, so only her SIM and number are associated with my O2 account now. The problem is that when I want to do anything with her account e.g. see if a cheaper tariff is available, the system insists on sending a security text message to the number on file i.e. hers, or it points me towards the O2 app but that isn't useful and not relevant to her 'thick' phone anyway.</P><P>&nbsp;</P><P>Is there any way I can ensure that all security prompts come to me on my own non-O2 number? It's pointless sending anything to her phone as she doesn't even understand what a text message is!</P><P>&nbsp;</P><P>On the face of it, I'm thinking the simplest option would be to move her to my new provider as well so that I can again have both numbers in one account for me to manage.</P><P>&nbsp;</P><P>Ideas?</P> Thu, 08 May 2025 11:16:26 GMT https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793009#M31068 Moggyman63 2025-05-08T11:16:26Z https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793010#M31069 <P>You say her SIM and number are associated with your O2 account. Can you still get into My O2? If so you can change the phone number in Contact Details to yours. Text will then be sent to you&nbsp;</P><P>&nbsp;</P> Thu, 08 May 2025 11:22:46 GMT https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793010#M31069 Enlli 2025-05-08T11:22:46Z https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793011#M31070 <P>I can still get into the O2 account OK.</P><P>I tried to change the number in Contact Details, but there is no option I can see that would route the security texts to my number.</P> Thu, 08 May 2025 11:27:29 GMT https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793011#M31070 Moggyman63 2025-05-08T11:27:29Z https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793013#M31071 <P>If your number is now the one in contact details. When a response is required it should give an option regarding which number the security text needs sending to.</P> Thu, 08 May 2025 11:44:42 GMT https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793013#M31071 Enlli 2025-05-08T11:44:42Z https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793014#M31072 <P>Best to use the web version of My O2</P><P>Hit the down arrow in the top left next to the mobile number</P><P>Scroll down to personal details then manage details</P><P>It will let you add your own number there</P> Thu, 08 May 2025 11:48:14 GMT https://community.o2.co.uk/t5/My-O2/Managing-a-number-belonging-to-someone-else/m-p/1793014#M31072 jonsie 2025-05-08T11:48:14Z
