I’ve just upgraded my phone through&nbsp;mobile phones direct and I’ve been sent a new sim. Should I use this new sim or my current? Do I need to call O2 to get anything switched over?&nbsp;<BR />Thanks in advance!</P> Tue, 09 Jan 2024 18:26:24 GMT https://community.o2.co.uk/t5/Apple/Upgraded-through-mobile-phones-direct/m-p/1684296#M172329 Cjfsmith98 2024-01-09T18:26:24Z https://community.o2.co.uk/t5/Apple/Upgraded-through-mobile-phones-direct/m-p/1684305#M172330 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/5437795">@Cjfsmith98</a>&nbsp;</P><P>If it was an upgrade you can use your old sim.</P><P>Just make sure you don't have two contracts running.</P><P>If you're in a 5g area you may want to do a sim swap to the new sim if your old one isn't 5g already <LI-PRODUCT title="Guide: Sim Swap: a mini guide 2017 update" id="Guide012"></LI-PRODUCT>&nbsp;</P> Tue, 09 Jan 2024 18:52:07 GMT https://community.o2.co.uk/t5/Apple/Upgraded-through-mobile-phones-direct/m-p/1684305#M172330 MI5 2024-01-09T18:52:07Z
