It is still showing&nbsp;my wifes&nbsp;designated email address and there appears no way of chaninging this, also the software does not appear to have been updated.</P><P>I can send/receive phone calls and texts although my wife's old texts are still showing.</P><P>Please advise how to move forward.</P> Sun, 20 Nov 2016 11:54:32 GMT https://community.o2.co.uk/t5/Android/Moving-sim-card-to-a-new-phone/m-p/1018595#M59540 Anonymous 2016-11-20T11:54:32Z https://community.o2.co.uk/t5/Android/Moving-sim-card-to-a-new-phone/m-p/1018600#M59541 <P>Best option is a factory reset and set up as new.</P> Sun, 20 Nov 2016 11:59:30 GMT https://community.o2.co.uk/t5/Android/Moving-sim-card-to-a-new-phone/m-p/1018600#M59541 jonsie 2016-11-20T11:59:30Z https://community.o2.co.uk/t5/Android/Moving-sim-card-to-a-new-phone/m-p/1018606#M59542 If you do a factory reset from Settings &gt;Security it will wipe everything from the phone and allow you to enter your own gmail and other personal details.
